Comparative lengths of
day and night
This month on the tour we will be attempting several of the most difficult
objects in the Catalog, a small faint planetary nebula, and a pair of face on
spiral galaxies. Also featured this month is a small, but fairly bright galaxy
and three open clusters. You will need binoculars and a telescope to fully enjoy
the January tour.
- M33 - This is a
very large (about the size of the full moon) face on spiral galaxy in the
constellation Triangulum. The total light from M33 is about magnitude 5.3, but
when spread out over its large area it yields a very low surface brightness. The
best and easiest views of M33 can be found with a pair of binoculars. Look for a
large, round hazy patch of light with little detail at first glance. M33 can be
glimpsed with the naked eye in dark clear skies. Finding M33 in a telescope can
be a challenge because of its size. Use the widest field eyepiece you have and
look for a change in light level to identify the galaxy.
- M103 - This is a
fairly small, sparse open cluster in Cassiopeia. Look for a tight group of stars
in binoculars, being careful not to mistake it for several other clusters in the
same area. Through a telescope the cluster is very sparse, four bright stars
amidst the slight glow of much fainter companions.
- M52 - This rich
open cluster in Cassiopeia is fairly easy to see in binoculars as a faint smudge
of light. A small to mid telescope will begin to resolve this cluster. Look for
a triangular patch of light with some stars clearly resolved, but most of the
cluster members provide only a hint of graininess.
- M76 - Known as the
little dumbbell, this planetary nebula in Perseus is one of the dimmest objects
in the Catalog. Look for a small, faint, oblong patch of light. Not a very
obvious object, if you don't see it at first try varying magnifications in an
attempt to bring it out. Fortunately M76 is located near a bright star which
aids in locating the correct field to search.
- M34 - This is a
large and bright, but sparse open cluster located in Perseus. Visible as a faint
patch of light to the naked eye, it is very obvious and easy to resolve in
binoculars. In fact, binoculars provide a better view of this cluster than most
telescopes.
- M74 - This galaxy
in Pisces is a smaller and fainter version of M33, a face on spiral galaxy with
low surface brightness. M74 is arguably the most difficult object to find in the
Catalog. You will need very dark, clear skies to easily see it, anything less
than perfect conditions will make M74 nearly impossible to find. Look for a very
faint fuzzy star, which is the bright central condensation, surrounded by a very
faint glow. Try all of your tricks on this one; star hop to the correct field,
try varying magnification, tap the scope to detect the galaxy through its
motion. If all of the above fail, try again another night or seek darker skies.
- M77 - This is a
small faint galaxy in Cetus. Possible to see in binoculars, but very difficult,
look for a faint fuzzy star. Through a telescope look for a fuzzy, oval shaped
patch of light, bright in the center, fading towards the edges.

For those in Northern Hemisphere, Capella, the "She Goat" in Aurigae, is
circumpolar. At my 47 deg North, Capella disappears behind the tree line, and
into the light polluted horizon, but she pops up in a few hours and is easy to
find. Also easy to find are epsilon Aurigae (al Maaz the Billy Goat) and "The
Kids" which make a small, long, triangle of stars just to the Southwest of
Capella.
For the next 21 months Epsilon Aurigae, usually the brightest of the trio,
will start behaving quite differently than it has for the past 27 years. Epsilon
Aurigae is a type of variable star called an eclipsing binary. Epsilon Aurigae
and some unknown dark partner, rotate around a common center of mass and every
27 years that dark companion eclipses the giant F-type star. August marks the
anticipated beginning for that eclipse which will last for 714 days, dimming
from 3.0 mag to about half of its brightness.
So why am I calling this a great astronomy activity? Epsilon Aurigae has some
definite quirks and more eyes are needed to help scientist figure out what
Epsilon Aurigae's invisible partner really is! We need help...WE NEED YOU!!
Anyone can participate; we need people to observe epsilon Aurigae, folks to look
at the data for quirks, patterns, or voids, artist to help present the data to
the public, friends willing to get the word out to others! To find out more

Comparative lengths of
day and night
This will be a fairly easy month on the tour. We will view two small, but
bright globular clusters, two open star clusters, and the grandest galaxy in the
sky along with it's two companions. All of these objects are possible to find in
binoculars, most are fairly easy.
- M2
- This is a small, bright globular cluster in Aquarius. To find it in
binoculars look for a fuzzy star in a star poor field. A low power telescope
field will show a round fuzzy patch, brighter in the center and fading to the
edge, in a field with no other bright objects.
- M15
- This globular cluster in Pegasus is very similar to M2 in size and
brightness, except it is surrounded by several bright stars. Fairly easy to find
in binoculars but the best view is through a telescope at medium to high power.
- M29
- This galactic cluster is a small, sparse group of stars in Cygnus. It
appears as a small fuzzy patch amongst a rich star field in binoculars. A
telescope will easily resolve the members of this cluster. The shape of the
cluster reminds me of the Pleiades as viewed through binoculars.
- M39
- Dark skies will allow this large, bright cluster in Cygnus to be seen with
the naked eye as a hazy patch of light. Binoculars easily resolve this cluster
into it's bright and widely scattered members, and provide a better view than
can be seen with most telescopes.
- M31
- This is the famous Andromeda Galaxy, our closest galactic neighbor, and the
largest, brightest galaxy to be seen in the northern sky. The ability to see M31
with the naked eye provides a good test of the darkness of your skies. M31 is so
large that binoculars provide the best view, allowing the entire galaxy to be
seen in one field of view. Look for an elongated patch of light, with a bright,
round central core.
- M32
- This is an elliptical companion galaxy to M31. Through a telescope look for
a slightly oval ball of fuzz in the same low power field as the core of M31. M32
is very possible to find in binoculars as a star like point of light.
- M110
- Another elliptical companion galaxy to M31, lying on the opposite side of
the core as M32. Through a telescope look for a large, oval patch of light.
Although M110 is as bright as M32 it is much larger and thus has a lower surface
brightness making it a difficult object in light polluted skies. M110 is a very
difficult binocular object requiring dark transparent skies, and trained eyes to
have a chance at finding it.

Interesting Planet Pairing for 2009
- December 31, 2008 - Jupiter and Mercury - After sunset a
little more than one degree apart in Sagittarius. Pull out the binos and
telescopes because Mercury will be a mere 15 arcminutes from the globular
cluster M75. All three will be together in one field of view in most home
binoculars.
- January 22nd - Venus and Uranus - After sunset 1.3 degrees
apart a few days later on the 29th they are joined by a waxing crescent moon.
- February 23rd - Jupiter, Mars and Mercury - In the early
morning sky just before sunrise the trio are in a space about 2 degrees wide.
Binoculars will be helpful but beware the quickly rising Sun. The Moon, almost
invisible, will be between Mars and the Sun.
- March 23rd - Mars, Moon, Neptune, and Jupiter - Makes a nice
line-up in the morning sky with Neptune just off the tip of the waning crescent
moon.
- April 21st - Venus, Mars, Uranus, waning crescent Moon, Neptune
and Jupiter - all in the pre-dawn sky together. First the right triangle of
Venus, Mars, and Uranus followed by the waning crescent Moon and then finally by
Neptune and Jupiter. Mars will be a faint 1.41 mag so binoculars will be
helpful. The next day, possible occultation of Venus by the Moon. Check the IOTA
website for occultations in your area.
- May 25th - Jupiter and Neptune - Jupiter is less than 1/2
degree South of Neptune in the morning sky. If you have ever had problems
finding Neptune this would be a good time to try, between now and June.
- June 19th - Venus and Mars - In the pre-dawn sky just south of
a waning crescent Moon. Closer to the Sun is Mercury and the Pleiades.
- August 17th - Saturn and Mercury - Very close to the Sun low
in the evening sky. Much better view for Southern viewers.
- September 3rd UT 4:43 - Jupiter hides its Galilean moons. Not
until 2019 will all of Jupiter's Galilean moons orbit in such a way.
- September 4th - Saturn - Not exactly a pairing but the Earth
will cross the plane of the rings from south to north making the rings invisible
- October 16th - Mercury, Venus, and Saturn - All lined up in
the pre-dawn sky close to the horizon. A faint waning crescent is just south of
the trio.
- December 24th - Jupiter and Neptune - Just after sunset
Jupiter and Neptune sit side-by-side just north of delta Capricornus and east of
the "42,44,45 Cap Wall"

Eclipses for 2009
January 26 - Annular Solar Eclipse ( see map,
times, and animation!): The first
solar eclipse of 2009 occurs at the Moon's ascending node in western
Capricornus. An annular eclipse will be visible from a wide track that traverses
the Indian Ocean and western Indonesia. A partial eclipse will be seen within
the much larger path of the Moon's penumbral shadow, which includes the southern
third of Africa, Madagascar, Australia except Tasmania, southeast India,
Southeast Asia and Indonesia.
February 09 - Penumbral Lunar Eclipse ( see map,
times): The first lunar eclipse of 2009 is one of four such events during
the year. The first three eclipses are penumbral while the last (on Dec. 31) is
partial. The Feb 09 event is the deepest penumbral eclipse of the year with a
penumbral magnitude of 0.899. It will be easily visible to the naked eye as a
dusky shading in the northern half of the Moon. The times of the major phases
are listed below.
July 07 - Penumbral Lunar Eclipse ( see map,
times.): July's penumbral eclipse is only of academic interest since the
magnitude is just 0.156. Although the Moon will be above the horizon from most
of Canada, the eclipse is so minor as to be completely invisible to the naked
eye.
July 21-22 - Total Solar Eclipse ( see map,
times, and animation!): To make up
for the anemic lunar eclipse earlier in the month, a major total eclipse of the
Sun occurs two weeks later. The path of the Moon's umbral shadow extends across
India, China, a handful of Japanese islands and the South Pacific Ocean (Espenak
and Anderson, 2008). A partial eclipse is seen within the much broader path of
the Moon's penumbral shadow, which includes most of eastern Asia, Indonesia, and
the Pacific Ocean.
August 05-06 - Penumbral Lunar Eclipse ( see map,
times): A shallow penumbral eclipse occurs 15 days after the total solar
eclipse. Since its magnitude is only 0.402, it will not be visible to the naked
eye.
December 31 - Penumbral Lunar Eclipse ( see map,
times): The last eclipse of 2009 occurs on New Year's Eve. This minor
partial lunar eclipse takes place in Gemini, and is visible primarily from the
Eastern Hemisphere (Figure 8). Greatest eclipse takes place at 19:23 UT when the
eclipse magnitude will reach 0.0763.

Information and Table Template Courtesy The American Meteor Society, International Meteor Organization, and Meteors Online.
Shower: named for the constellation or closest star within a
constellation where the radiant is located at maximum activity.
Activity Period: the dates when the ZHR (Zenith Hourly Rates) are
equal to or greater than one.
Maximum: the date on which the maximum activity is expected to occur.
S.L.: the equivalent solar longitude of the date of maximum
activity. Solar longitude is measured in degrees (0-359) with 0 occurring at the
exact moment of the spring equinox, 90 at the summer solstice, 180 at the
autumnal equinox, and 270 at the winter solstice.
Radiant: the area in the sky where shower meteors seem to appear from.
This position is given in right ascension (celestial longitude) and
declination (celestial latitude).
Velocity: the velocity at which shower meteors strike the Earth's
atmosphere. The velocity depends on the angle meteoroids (meteors in space)
intersect the Earth. Meteoroids orbiting in the opposite direction of the Earth
and striking the atmosphere head-on are much faster than those orbiting in the
same direction as the Earth. This velocity is measured in kilometers per second.
r: The Population Index, An estimate of the ratio of the number
of meteors in subsequent magnitude classes. Simply stated: the lower the "r"
value, the resulting overall mean magnitude of each shower will be brighter. "r"
usually ranges from 2.0 (bright) to 3.5 (faint).
ZHR: Zenith Hourly Rate, the average maximum number of shower
meteors visible per hour if the radiant is located exactly overhead and the
limiting magnitude equals +6.5. Actual counts rarely reach this figure as the
zenith angle of the radiant is usually less and the limiting magnitude is
usually lower. ZHR is a useful tool when comparing the actual observed rates
between individual observers as it sets observing conditions for all to the same
standards.
Class: A scale developed by Robert Lunsford to group meteor showers by
their intensity:
Class I: the strongest annual showers with ZHR's normally ten or
better.
Class II: reliable minor showers with ZHR's normally three or better.
Class III: showers with widely variable rates. They may be strong one
year and totally inactive the next.
Class IV: weak minor showers with ZHR's rarely exceeding three. The
study of these showers is best left to experienced observers who use plotting
and angular velocity estimates to determine shower association. Observers with
less experience are urged to limit their shower associations to showers with a
rating of I to III. These showers are also good targets for video and
photographic work.
Moon: the age of the moon in days where 0 is new, 7 is first quarter,
14 is full, and 21 is last quarter. Meteor activity is best seen in the absence
of moonlight so showers reaching maximum activity when the moon is less than 10
days old or more than 25 are much more favorably observed than those situated
closer to the full moon.

For those in Northern Hemisphere, Capella, the "She Goat" in Aurigae, is
circumpolar. At my 47 deg North, Capella disappears behind the tree line, and
into the light polluted horizon, but she pops up in a few hours and is easy to
find. Also easy to find are epsilon Aurigae (al Maaz the Billy Goat) and "The
Kids" which make a small, long, triangle of stars just to the Southwest of
Capella.
For the next 21 months Epsilon Aurigae, usually the brightest of the trio,
will start behaving quite differently than it has for the past 27 years. Epsilon
Aurigae is a type of variable star called an eclipsing binary. Epsilon Aurigae
and some unknown dark partner, rotate around a common center of mass and every
27 years that dark companion eclipses the giant F-type star. August marks the
anticipated beginning for that eclipse which will last for 714 days, dimming
from 3.0 mag to about half of its brightness.
So why am I calling this a great astronomy activity? Epsilon Aurigae has some
definite quirks and more eyes are needed to help scientist figure out what
Epsilon Aurigae's invisible partner really is! We need help...WE NEED YOU!!
Anyone can participate; we need people to observe epsilon Aurigae, folks to look
at the data for quirks, patterns, or voids, artist to help present the data to
the public, friends willing to get the word out to others! To find out more

NASA's MicroObservatories
Another fantastic project, that AAGG is supporting all through the month of
September, it the "Capture the Colorful Cosmos" project using the NASA
MicroObservatories. This project gives you the opportunity to direct a robotic
telescope and then manipulate the resulting images!
I had the opportunity to help school age kids, and some kid-like adults,
through the project at the Tacoma Astronomical Society's annual Astronomy Fair
in August and we had a wonderful time! They were using filter, shifting and
stacking images, and turning out images like the pros!

LCROSS ImpactAstronomers, amateur and professional a like, who
have access to dark skies and large aperture scopes are encouraged to
participate in imaging and video taping the impact of the Centaur impactor and
the LCROSS satellite with the Moon. The primary objective of the Lunar Crater
Observation and Sensing Satellite (LCROSS) is to confirm the presence or absence
of water ice in the Moon's polar region. But the amazing bit will be the five
body choreography between the Moon, the Centaur rocket/impactor, the Shepherding
craft/research vessel/impactor, and LRO (who was launched with LCROSS) who will
also observe the action, and YOU, on Earth!
I mean... what other impactor mission has its own music
video!

This month our monthly Messier hits some big easy targets, eight more
globular clusters, all are possible in binoculars, and two of these are the
finest globulars which can be seen from northern locations.
Sagittarius is the home of many globular clusters which surround the center
of the Milky Way Galaxy. Seven of the these globulars appear in the Messier
catalog, we will be visiting five of them this month. When you complete the
search for these objects be sure to spend some time scanning this region with
binoculars or a telescope and see what other sights you can discover. I
guarantee you will not be disappointed.
- M13 - The great
globular cluster in Hercules is bright enough to be seen with naked eye and
typically the first GC found by amateur astronomers in the NH. Binoculars easily
show this cluster as a bright fuzzy ball. M13 is partially resolvable in small
aperture telescopes and becomes a fantastic swarm of tightly packed individual
stars through large scopes.
- M92 - Another
globular cluster in Hercules, M92 is easy to find in binoculars appearing
slightly dimmer and smaller than M13. As with M13 it is partially resolvable in
small scopes and is a fine sight in large instruments.
- M14 - A small,
bright globular cluster in Ophiuchus. It is a difficult binocular object, look
for a small fuzzy patch of light. Through a telescope M14 is an even patch of
light, the stars not resolvable except through large scopes.
- M22 - This is
the other great globular in our tour this month. Located just above the teapot
asterism in Sagittarius, M22 can be seen with no optical aid. M22 is easy to
find in binoculars, and easy to resolve in telescopes, with about the same
impressiveness as M13.
- M28 - Located
near M22 in Sagittarius, this is a small bright globular. A tough binocular
object, look for a small fuzzy patch. Easily seen in a telescope, but requires
large aperture to resolve individual stars.
- M69, M70, M54 All of these are small
bright globular clusters laying along the bottom of the teapot in Sagittarius.
Very similar in appearance to M28, these are all tough binocular objects
requiring dark skies and possibly averted vision to see. M54 is slightly
brighter and appears more star like through binoculars than the other globulars.
These are all easily seen in telescopes, though not easily resolvable.

Interesting Planet Pairing for 2009
- December 31, 2008 - Jupiter and Mercury - After sunset a
little more than one degree apart in Sagittarius. Pull out the binos and
telescopes because Mercury will be a mere 15 arcminutes from the globular
cluster M75. All three will be together in one field of view in most home
binoculars.
- January 22nd - Venus and Uranus - After sunset 1.3 degrees
apart a few days later on the 29th they are joined by a waxing crescent moon.
- February 23rd - Jupiter, Mars and Mercury - In the early
morning sky just before sunrise the trio are in a space about 2 degrees wide.
Binoculars will be helpful but beware the quickly rising Sun. The Moon, almost
invisible, will be between Mars and the Sun.
- March 23rd - Mars, Moon, Neptune, and Jupiter - Makes a nice
line-up in the morning sky with Neptune just off the tip of the waning crescent
moon.
- April 21st - Venus, Mars, Uranus, waning crescent Moon, Neptune
and Jupiter - all in the pre-dawn sky together. First the right triangle of
Venus, Mars, and Uranus followed by the waning crescent Moon and then finally by
Neptune and Jupiter. Mars will be a faint 1.41 mag so binoculars will be
helpful. The next day, possible occultation of Venus by the Moon. Check the IOTA
website for occultations in your area.
- May 25th - Jupiter and Neptune - Jupiter is less than 1/2
degree South of Neptune in the morning sky. If you have ever had problems
finding Neptune this would be a good time to try, between now and June.
- June 19th - Venus and Mars - In the pre-dawn sky just south of
a waning crescent Moon. Closer to the Sun is Mercury and the Pleiades.
- August 17th - Saturn and Mercury - Very close to the Sun low
in the evening sky. Much better view for Southern viewers.
- September 3rd UT 4:43 - Jupiter hides its Galilean moons. Not
until 2019 will all of Jupiter's Galilean moons orbit in such a way.
- September 4th - Saturn - Not exactly a pairing but the Earth
will cross the plane of the rings from south to north making the rings invisible
- October 16th - Mercury, Venus, and Saturn - All lined up in
the pre-dawn sky close to the horizon. A faint waning crescent is just south of
the trio.
- December 24th - Jupiter and Neptune - Just after sunset
Jupiter and Neptune sit side-by-side just north of delta Capricornus and east of
the "42,44,45 Cap Wall"

Eclipses for 2009
January 26 - Annular Solar Eclipse ( see map,
times, and animation!): The first
solar eclipse of 2009 occurs at the Moon's ascending node in western
Capricornus. An annular eclipse will be visible from a wide track that traverses
the Indian Ocean and western Indonesia. A partial eclipse will be seen within
the much larger path of the Moon's penumbral shadow, which includes the southern
third of Africa, Madagascar, Australia except Tasmania, southeast India,
Southeast Asia and Indonesia.
February 09 - Penumbral Lunar Eclipse ( see map,
times): The first lunar eclipse of 2009 is one of four such events during
the year. The first three eclipses are penumbral while the last (on Dec. 31) is
partial. The Feb 09 event is the deepest penumbral eclipse of the year with a
penumbral magnitude of 0.899. It will be easily visible to the naked eye as a
dusky shading in the northern half of the Moon. The times of the major phases
are listed below.
July 07 - Penumbral Lunar Eclipse ( see map,
times.): July's penumbral eclipse is only of academic interest since the
magnitude is just 0.156. Although the Moon will be above the horizon from most
of Canada, the eclipse is so minor as to be completely invisible to the naked
eye.
July 21-22 - Total Solar Eclipse ( see map,
times, and animation!): To make up
for the anemic lunar eclipse earlier in the month, a major total eclipse of the
Sun occurs two weeks later. The path of the Moon's umbral shadow extends across
India, China, a handful of Japanese islands and the South Pacific Ocean (Espenak
and Anderson, 2008). A partial eclipse is seen within the much broader path of
the Moon's penumbral shadow, which includes most of eastern Asia, Indonesia, and
the Pacific Ocean.
August 05-06 - Penumbral Lunar Eclipse ( see map,
times): A shallow penumbral eclipse occurs 15 days after the total solar
eclipse. Since its magnitude is only 0.402, it will not be visible to the naked
eye.
December 31 - Penumbral Lunar Eclipse ( see map,
times): The last eclipse of 2009 occurs on New Year's Eve. This minor
partial lunar eclipse takes place in Gemini, and is visible primarily from the
Eastern Hemisphere (Figure 8). Greatest eclipse takes place at 19:23 UT when the
eclipse magnitude will reach 0.0763.

Information and Table Template Courtesy The American Meteor Society, International Meteor Organization, and Meteors Online.
Shower: named for the constellation or closest star within a
constellation where the radiant is located at maximum activity.
Activity Period: the dates when the ZHR (Zenith Hourly Rates) are
equal to or greater than one.
Maximum: the date on which the maximum activity is expected to occur.
S.L.: the equivalent solar longitude of the date of maximum
activity. Solar longitude is measured in degrees (0-359) with 0 occurring at the
exact moment of the spring equinox, 90 at the summer solstice, 180 at the
autumnal equinox, and 270 at the winter solstice.
Radiant: the area in the sky where shower meteors seem to appear from.
This position is given in right ascension (celestial longitude) and
declination (celestial latitude).
Velocity: the velocity at which shower meteors strike the Earth's
atmosphere. The velocity depends on the angle meteoroids (meteors in space)
intersect the Earth. Meteoroids orbiting in the opposite direction of the Earth
and striking the atmosphere head-on are much faster than those orbiting in the
same direction as the Earth. This velocity is measured in kilometers per second.
r: The Population Index, An estimate of the ratio of the number
of meteors in subsequent magnitude classes. Simply stated: the lower the "r"
value, the resulting overall mean magnitude of each shower will be brighter. "r"
usually ranges from 2.0 (bright) to 3.5 (faint).
ZHR: Zenith Hourly Rate, the average maximum number of shower
meteors visible per hour if the radiant is located exactly overhead and the
limiting magnitude equals +6.5. Actual counts rarely reach this figure as the
zenith angle of the radiant is usually less and the limiting magnitude is
usually lower. ZHR is a useful tool when comparing the actual observed rates
between individual observers as it sets observing conditions for all to the same
standards.
Class: A scale developed by Robert Lunsford to group meteor showers by
their intensity:
Class I: the strongest annual showers with ZHR's normally ten or
better.
Class II: reliable minor showers with ZHR's normally three or better.
Class III: showers with widely variable rates. They may be strong one
year and totally inactive the next.
Class IV: weak minor showers with ZHR's rarely exceeding three. The
study of these showers is best left to experienced observers who use plotting
and angular velocity estimates to determine shower association. Observers with
less experience are urged to limit their shower associations to showers with a
rating of I to III. These showers are also good targets for video and
photographic work.
Moon: the age of the moon in days where 0 is new, 7 is first quarter,
14 is full, and 21 is last quarter. Meteor activity is best seen in the absence
of moonlight so showers reaching maximum activity when the moon is less than 10
days old or more than 25 are much more favorably observed than those situated
closer to the full moon.

Planets for July 2009
July Morning Planets
(click images to enlarge)
Beginning of the month
Pre-dawn, July 18th
- Mercury-in superior conjunction on the 14th. If you are on the path
of the Total Solar Eclipse then look for Mercury 9 degrees NE of the Sun. At the
end of the month, Southern viewers can catch Mercury in the early evening. -0.9
mag (1st) to -1.3 mag (21st)
- Venus- still fantastic in the morning pre-dawn sky. Since Venus is
moving towards the North, as the Sun heads South, her placement it spectacular
for N. Hemisphere viewers. On the 14th she will be just 3 degrees from Aldebaran
and the Hyades -4.0 mag (1st) to -3.9 mag (21st)
- Mars- moves into Taurus on the 2nd. Mars, Venus, the waning crescent
Moon, and the Hyades make a lovely cluster on the 18th. Compare Mars, and its
color, to that of Aldebaran. 1.1 (1st) to 1.1 mag (21st)
- Jupiter- will be ~ .5 degree from Neptune on the 13th! Jupiter will
be at opposition on August 14th. -2.7 mag (1st) to -2.7 mag (21st)
- Saturn- strangely faint low in the west after sunset! The combination
of the rings near edge on and the receding gas giant decrease the apparent
magnitude. 1.0 mag (1st) to 1.0 mag (21st)
- Uranus- In Aquarius 5.9 mag (1st) to 5.9 mag (21st)
- Neptune- In Capricorn 8.0 mag (1st) to 7.9 mag (21st)

Great Amateur Activity
For those in the high Northern Hemisphere, Capella, the "she goat" in
Aurigae, is circumpolar. At my 47 deg North, Capella disappears behind the
treeline, and into the light polluted horizon, but she pops up in a few hours
and is easy to find. Also easy to find are "The Kids" the small, long, triangle
of stars just to the Southwest of Capella. However, this summer one of those
kids, Epsilon Aurigae, usually the brightest of the trio, will drop in
brightness....for about two years. Epsilon Aurigae, or Almaaz, is an eclipsing
binary and beginning in Aug it will be eclipsed by its invisible companion for
714 days! Brightest of the three "Kids" Epsilon Aurigae will dim from 3.0 mag to
about half of its brightness, a little trick it performs every 27.1 years.
Epsilon Aurigae has some definite quirks and more eyes are needed to help
scientist figure out what Epsilon Aurigae's invisible partner really is! To find
out more visit:
Not as many
objects as wait for the summer Milkyway to rise into better view later this
summer, but much of what there is to see can be accomplished with binoculars.
(This is, in fact, my favorite time of the year for bino viewing.) Our quarry
will consist of six globular clusters and one very bright galaxy. Small scope
and bino heaven.
- M3
- This globular cluster in Canes Venatici is one of the brightest objects in
the sky. In binoculars this object is definitely not star like, but more of a
bright, small snowball easy to see. Small telescopes will begin to resolve M3
into individual stars. The hardest part of this object is locating it in a
portion of sky that contains few bright landmarks.
- M53
- Another globular cluster in Canes Venatici. While not quite as big or bright
as M3 it is still an obvious binocular object. Resolvable in small telescopes,
it as easy object to find sharing the same low power telescope field as fifth
magnitude Alpha Coma Berenices.
- M5
- A big, bright globular cluster located in Serpens Caput. M5 is as nice as M3
but lies near a fifth magnitude naked eye star (5 Serpentis) making it an easy
object to find.
- M68
- An eighth magnitude globular cluster in Hydra, M68 is a difficult binocular
object for Northern observers. It appears as a faint fuzz spot in binoculars,
you may need to use averted vision or large binoculars to find this one.
Appearing as a round fuzzy patch in a 8" telescope, you will need a much larger
aperature to really resolve it.
- M83
- A face on spiral in Hydra. M83 is fairly easy in binoculars as a faint,
fuzzy patch of light. In a telescope look for a large patch of light with a
bright center.
- M4
- A big bright globular in Scorpius, easily located near Antares. This is an
easy binocular object appearing as a round snowball. Partially resolvable in a
telescope, the trade mark of this globular is a line of bright stars crossing
the center.
- M80
- This is the smallest and faintest globular cluster this month. Located in
Scopius, M80 is a very tough binocular object appearing as a faint star with
slight fuzziness around the edges. This is confirmed with a telescope, M80 has a
bright central condensation in the middle of faint fuzz. It is one of the
Messier objects that even through a medium telescope still looks like a comet.

Interesting Planet Pairing for 2009
- December 31, 2008 - Jupiter and Mercury - After sunset a
little more than one degree apart in Sagittarius. Pull out the binos and
telescopes because Mercury will be a mere 15 arcminutes from the globular
cluster M75. All three will be together in one field of view in most home
binoculars.
- January 22nd - Venus and Uranus - After sunset 1.3 degrees
apart a few days later on the 29th they are joined by a waxing crescent moon.
- February 23rd - Jupiter, Mars and Mercury - In the early
morning sky just before sunrise the trio are in a space about 2 degrees wide.
Binoculars will be helpful but beware the quickly rising Sun. The Moon, almost
invisible, will be between Mars and the Sun.
- March 23rd - Mars, Moon, Neptune, and Jupiter - Makes a nice
line-up in the morning sky with Neptune just off the tip of the waning crescent
moon.
- April 21st - Venus, Mars, Uranus, waning crescent Moon, Neptune
and Jupiter - all in the pre-dawn sky together. First the right triangle of
Venus, Mars, and Uranus followed by the waning crescent Moon and then finally by
Neptune and Jupiter. Mars will be a faint 1.41 mag so binoculars will be
helpful. The next day, possible occultation of Venus by the Moon. Check the IOTA
website for occultations in your area.
- May 25th - Jupiter and Neptune - Jupiter is less than 1/2
degree South of Neptune in the morning sky. If you have ever had problems
finding Neptune this would be a good time to try, between now and June.
- June 19th - Venus and Mars - In the pre-dawn sky just south of
a waning crescent Moon. Closer to the Sun is Mercury and the Pleiades.
- August 17th - Saturn and Mercury - Very close to the Sun low
in the evening sky. Much better view for Southern viewers.
- September 3rd UT 4:43 - Jupiter hides its Galilean moons. Not
until 2019 will all of Jupiter's Galilean moons orbit in such a way.
- September 4th - Saturn - Not exactly a pairing but the Earth
will cross the plane of the rings from south to north making the rings invisible
- October 16th - Mercury, Venus, and Saturn - All lined up in
the pre-dawn sky close to the horizon. A faint waning crescent is just south of
the trio.
- December 24th - Jupiter and Neptune - Just after sunset
Jupiter and Neptune sit side-by-side just north of delta Capricornus and east of
the "42,44,45 Cap Wall"

Eclipses for 2009
January 26 - Annular Solar Eclipse ( see map,
times, and animation!): The first
solar eclipse of 2009 occurs at the Moon's ascending node in western
Capricornus. An annular eclipse will be visible from a wide track that traverses
the Indian Ocean and western Indonesia. A partial eclipse will be seen within
the much larger path of the Moon's penumbral shadow, which includes the southern
third of Africa, Madagascar, Australia except Tasmania, southeast India,
Southeast Asia and Indonesia.
February 09 - Penumbral Lunar Eclipse ( see map,
times): The first lunar eclipse of 2009 is one of four such events during
the year. The first three eclipses are penumbral while the last (on Dec. 31) is
partial. The Feb 09 event is the deepest penumbral eclipse of the year with a
penumbral magnitude of 0.899. It will be easily visible to the naked eye as a
dusky shading in the northern half of the Moon. The times of the major phases
are listed below.
July 07 - Penumbral Lunar Eclipse ( see map,
times.): July's penumbral eclipse is only of academic interest since the
magnitude is just 0.156. Although the Moon will be above the horizon from most
of Canada, the eclipse is so minor as to be completely invisible to the naked
eye.
July 21-22 - Total Solar Eclipse ( see map,
times, and animation!): To make up
for the anemic lunar eclipse earlier in the month, a major total eclipse of the
Sun occurs two weeks later. The path of the Moon's umbral shadow extends across
India, China, a handful of Japanese islands and the South Pacific Ocean (Espenak
and Anderson, 2008). A partial eclipse is seen within the much broader path of
the Moon's penumbral shadow, which includes most of eastern Asia, Indonesia, and
the Pacific Ocean.
August 05-06 - Penumbral Lunar Eclipse ( see map,
times): A shallow penumbral eclipse occurs 15 days after the total solar
eclipse. Since its magnitude is only 0.402, it will not be visible to the naked
eye.
December 31 - Penumbral Lunar Eclipse ( see map,
times): The last eclipse of 2009 occurs on New Year's Eve. This minor
partial lunar eclipse takes place in Gemini, and is visible primarily from the
Eastern Hemisphere (Figure 8). Greatest eclipse takes place at 19:23 UT when the
eclipse magnitude will reach 0.0763.

Information and Table Template Courtesy The American Meteor Society, International Meteor Organization, and Meteors Online.
Shower: named for the constellation or closest star within a
constellation where the radiant is located at maximum activity.
Activity Period: the dates when the ZHR (Zenith Hourly Rates) are
equal to or greater than one.
Maximum: the date on which the maximum activity is expected to occur.
S.L.: the equivalent solar longitude of the date of maximum
activity. Solar longitude is measured in degrees (0-359) with 0 occurring at the
exact moment of the spring equinox, 90 at the summer solstice, 180 at the
autumnal equinox, and 270 at the winter solstice.
Radiant: the area in the sky where shower meteors seem to appear from.
This position is given in right ascension (celestial longitude) and
declination (celestial latitude).
Velocity: the velocity at which shower meteors strike the Earth's
atmosphere. The velocity depends on the angle meteoroids (meteors in space)
intersect the Earth. Meteoroids orbiting in the opposite direction of the Earth
and striking the atmosphere head-on are much faster than those orbiting in the
same direction as the Earth. This velocity is measured in kilometers per second.
r: The Population Index, An estimate of the ratio of the number
of meteors in subsequent magnitude classes. Simply stated: the lower the "r"
value, the resulting overall mean magnitude of each shower will be brighter. "r"
usually ranges from 2.0 (bright) to 3.5 (faint).
ZHR: Zenith Hourly Rate, the average maximum number of shower
meteors visible per hour if the radiant is located exactly overhead and the
limiting magnitude equals +6.5. Actual counts rarely reach this figure as the
zenith angle of the radiant is usually less and the limiting magnitude is
usually lower. ZHR is a useful tool when comparing the actual observed rates
between individual observers as it sets observing conditions for all to the same
standards.
Class: A scale developed by Robert Lunsford to group meteor showers by
their intensity:
Class I: the strongest annual showers with ZHR's normally ten or
better.
Class II: reliable minor showers with ZHR's normally three or better.
Class III: showers with widely variable rates. They may be strong one
year and totally inactive the next.
Class IV: weak minor showers with ZHR's rarely exceeding three. The
study of these showers is best left to experienced observers who use plotting
and angular velocity estimates to determine shower association. Observers with
less experience are urged to limit their shower associations to showers with a
rating of I to III. These showers are also good targets for video and
photographic work.
Moon: the age of the moon in days where 0 is new, 7 is first quarter,
14 is full, and 21 is last quarter. Meteor activity is best seen in the absence
of moonlight so showers reaching maximum activity when the moon is less than 10
days old or more than 25 are much more favorably observed than those situated
closer to the full moon.

This month we
continue our tour of our nearby neighbors outside the Milky May galaxy. Our
observing will take in 10 more galaxies. Be ready to look for very faint and
small objects. Most are possible to see in binoculars, but you will need a
telescope and dark skies to really enjoy the sights. This is the final warm up
to prepare us for next month's challenge, navigating the Virgo Cluster of
galaxies. When you are done with these objects and give yourself a treat, skip
ahead to the summer globular clusters of M3 or M13. While they are not an
official part of this month's tour they should never be missed whenever they are
available. Besides these bright and spectacular objects are a treat to tired
eyes after a night of galaxy hunting. Be careful, these are so bright after the
other objects that you might want to wear shades.
 M51
- The famous Whirlpool galaxy in Canes Venatici is a bright face on spiral
with a smaller elliptical companion, NGC 5195. Look for a pair of fuzzy patches
of light. The slightly larger and brighter one is M51. Make sure to spend some
time here as there is almost always some spiral structure to be seen, on good
nights the detail possible is unbelievable. This is a difficult but very
possible object in binoculars appearing as a hazy patch of light.
 M63
- Another spiral galaxy in Canes Venatici smaller and fainter than M51, but
seen more edge on so the galaxy appears as an elongated patch of light with a
bright star at one end. Further inspection will show a faint halo around this
patch. A difficult object in binoculars.
 M94
- Just past M63 is another galaxy in Canes Vanitici. Look for a bright fuzzy
star to find the core of M94, surrounded by a faint haze. A tough binocular
object.
 M101
- I consider this face on spiral galaxy in Ursa Major one of the most
difficult Messier objects to find in a telescope. This is a large faint patch of
light almost as big as the full moon. There are no real condensations so use low
power and look for a brighter part of the sky, more of a change in contrast than
an object at first glance, which is the galaxy. Dark skies really help in the
search of this one and are a to find M101 in binoculars.
 M102
- Not an official Messier object in most references, we will look for the
galaxy NGC 5866
which is a somewhat standard insertion. Look for a small, faint patch light that
looks like a short fuzzy line.
 M64
- In a telescope this galaxy in Coma Berenices is a fairly bright, slightly
oval shaped patch of light. Look for the dark lane which gives this galaxy the
common name Black Eye. The galaxy appears as a faint fuzzy patch in binoculars.
 M85
- This elliptical galaxy lies in Coma Berenices just north of the Virgo
Cluster of galaxies. This appears as a bright, but small, patch of light with a
bright stellar core.
 M49
- This is an elliptical galaxy in Virgo just south of the main cluster of
galaxies. M49 is round patch of light with bright center gradually fading to a
round halo. M49 looks like a faint fuzzy star in binoculars.
 M61
- This is a face on spiral galaxy just south of M49 in Virgo, but much
fainter. Look for a faint, round fuzzy patch of light.
 M104
- This is the well known Sombrero galaxy in Virgo. It is bright edge on spiral
galaxy which looks like a bright, elongated streak. It is very possible to see
in binoculars.

Interesting Planet Pairing for 2009
- December 31, 2008 - Jupiter and Mercury - After sunset a
little more than one degree apart in Sagittarius. Pull out the binos and
telescopes because Mercury will be a mere 15 arcminutes from the globular
cluster M75. All three will be together in one field of view in most home
binoculars.
- January 22nd - Venus and Uranus - After sunset 1.3 degrees
apart a few days later on the 29th they are joined by a waxing crescent moon.
- February 23rd - Jupiter, Mars and Mercury - In the early
morning sky just before sunrise the trio are in a space about 2 degrees wide.
Binoculars will be helpful but beware the quickly rising Sun. The Moon, almost
invisible, will be between Mars and the Sun.
- March 23rd - Mars, Moon, Neptune, and Jupiter - Makes a nice
line-up in the morning sky with Neptune just off the tip of the waning crescent
moon.
- April 21st - Venus, Mars, Uranus, waning crescent Moon, Neptune
and Jupiter - all in the pre-dawn sky together. First the right triangle of
Venus, Mars, and Uranus followed by the waning crescent Moon and then finally by
Neptune and Jupiter. Mars will be a faint 1.41 mag so binoculars will be
helpful. The next day, possible occultation of Venus by the Moon. Check the IOTA
website for occultations in your area.
- May 25th - Jupiter and Neptune - Jupiter is less than 1/2
degree South of Neptune in the morning sky. If you have ever had problems
finding Neptune this would be a good time to try, between now and June.
- June 19th - Venus and Mars - In the pre-dawn sky just south of
a waning crescent Moon. Closer to the Sun is Mercury and the Pleiades.
- August 17th - Saturn and Mercury - Very close to the Sun low
in the evening sky. Much better view for Southern viewers.
- September 3rd UT 4:43 - Jupiter hides its Galilean moons. Not
until 2019 will all of Jupiter's Galilean moons orbit in such a way.
- September 4th - Saturn - Not exactly a pairing but the Earth
will cross the plane of the rings from south to north making the rings invisible
- October 16th - Mercury, Venus, and Saturn - All lined up in
the pre-dawn sky close to the horizon. A faint waning crescent is just south of
the trio.
- December 24th - Jupiter and Neptune - Just after sunset

Eclipses for 2009
January 26 - Annular Solar Eclipse ( see map,
times, and animation!): The first
solar eclipse of 2009 occurs at the Moon's ascending node in western
Capricornus. An annular eclipse will be visible from a wide track that traverses
the Indian Ocean and western Indonesia. A partial eclipse will be seen within
the much larger path of the Moon's penumbral shadow, which includes the southern
third of Africa, Madagascar, Australia except Tasmania, southeast India,
Southeast Asia and Indonesia.
February 09 - Penumbral Lunar Eclipse ( see map,
times): The first lunar eclipse of 2009 is one of four such events during
the year. The first three eclipses are penumbral while the last (on Dec. 31) is
partial. The Feb 09 event is the deepest penumbral eclipse of the year with a
penumbral magnitude of 0.899. It will be easily visible to the naked eye as a
dusky shading in the northern half of the Moon. The times of the major phases
are listed below.
July 07 - Penumbral Lunar Eclipse ( see map,
times.): July's penumbral eclipse is only of academic interest since the
magnitude is just 0.156. Although the Moon will be above the horizon from most
of Canada, the eclipse is so minor as to be completely invisible to the naked
eye.
July 21-22 - Total Solar Eclipse ( see map,
times, and animation!): To make up
for the anemic lunar eclipse earlier in the month, a major total eclipse of the
Sun occurs two weeks later. The path of the Moon's umbral shadow extends across
India, China, a handful of Japanese islands and the South Pacific Ocean (Espenak
and Anderson, 2008). A partial eclipse is seen within the much broader path of
the Moon's penumbral shadow, which includes most of eastern Asia, Indonesia, and
the Pacific Ocean.
August 05-06 - Penumbral Lunar Eclipse ( see map,
times): A shallow penumbral eclipse occurs 15 days after the total solar
eclipse. Since its magnitude is only 0.402, it will not be visible to the naked
eye.
December 31 - Penumbral Lunar Eclipse ( see map,
times): The last eclipse of 2009 occurs on New Year's Eve. This minor
partial lunar eclipse takes place in Gemini, and is visible primarily from the
Eastern Hemisphere (Figure 8). Greatest eclipse takes place at 19:23 UT when the
eclipse magnitude will reach 0.0763.

Information and Table Template Courtesy The American Meteor Society, International Meteor Organization, and Meteors Online.
Shower: named for the constellation or closest star within a
constellation where the radiant is located at maximum activity.
Activity Period: the dates when the ZHR (Zenith Hourly Rates) are
equal to or greater than one.
Maximum: the date on which the maximum activity is expected to occur.
S.L.: the equivalent solar longitude of the date of maximum
activity. Solar longitude is measured in degrees (0-359) with 0 occurring at the
exact moment of the spring equinox, 90 at the summer solstice, 180 at the
autumnal equinox, and 270 at the winter solstice.
Radiant: the area in the sky where shower meteors seem to appear from.
This position is given in right ascension (celestial longitude) and
declination (celestial latitude).
Velocity: the velocity at which shower meteors strike the Earth's
atmosphere. The velocity depends on the angle meteoroids (meteors in space)
intersect the Earth. Meteoroids orbiting in the opposite direction of the Earth
and striking the atmosphere head-on are much faster than those orbiting in the
same direction as the Earth. This velocity is measured in kilometers per second.
r: The Population Index, An estimate of the ratio of the number
of meteors in subsequent magnitude classes. Simply stated: the lower the "r"
value, the resulting overall mean magnitude of each shower will be brighter. "r"
usually ranges from 2.0 (bright) to 3.5 (faint).
ZHR: Zenith Hourly Rate, the average maximum number of shower
meteors visible per hour if the radiant is located exactly overhead and the
limiting magnitude equals +6.5. Actual counts rarely reach this figure as the
zenith angle of the radiant is usually less and the limiting magnitude is
usually lower. ZHR is a useful tool when comparing the actual observed rates
between individual observers as it sets observing conditions for all to the same
standards.
Class: A scale developed by Robert Lunsford to group meteor showers by
their intensity:
Class I: the strongest annual showers with ZHR's normally ten or
better.
Class II: reliable minor showers with ZHR's normally three or better.
Class III: showers with widely variable rates. They may be strong one
year and totally inactive the next.
Class IV: weak minor showers with ZHR's rarely exceeding three. The
study of these showers is best left to experienced observers who use plotting
and angular velocity estimates to determine shower association. Observers with
less experience are urged to limit their shower associations to showers with a
rating of I to III. These showers are also good targets for video and
photographic work.
Moon: the age of the moon in days where 0 is new, 7 is first quarter,
14 is full, and 21 is last quarter. Meteor activity is best seen in the absence
of moonlight so showers reaching maximum activity when the moon is less than 10
days old or more than 25 are much more favorably observed than those situated
closer to the full moon.

I"m not sure what happened to March and April kept reverting to February but I think April is now fixed. So very sorry.
The main thing to look for in April is next week so take a look at the calendar.
Sorry....again.

Planets for April 2009April will be a morning viewing month for planets with a lovely lunar meet and greet with Jupiter and Mars and an occultation of Venus. Saturn is available for evening viewers!
April Morning Planets
(click images to enlarge)
Beginning of the month
April 21st
- Mercury- In superior conjunction on March 31st look for Mercury at its greatest elongation east on April 26th. This will be the Northern H. best view all year. Look just between the waxing crescent Moon and the horizon just after sunset -2.1 mag (1st) to -0.4 mag (21st)
April 26th
- Venus- Just stunning in the morning sky growing to -4.7 after mid month. Watch for the lunar occultation starting just around sunrise and ending about an hour later! Large binos and small telescope should catch the action! -3.9 mag (1st) to -4.4 mag (21st)
 
Venus just before sunrise passing behind the Moon....and later, after sunrise, reappearing
- Mars- Finally starts to get brighter and over the next few months Mars will run (almost) a circle around Venus as their positions change in relation to Earth. This little game of tag within the constellations will be fun to watch for the next several months. 1.2 (1st) to 1.2 mag (21st)
- Jupiter- Should be high enough in the morning to be seen. (unless you are in Seattle and we have our perpetual planet zapping cloud banks) Look for Jupiter during the day on the 19th as the Moon passes close by. On the 26th pull out the telescope and see if you can catch the "fake moon" mag 5.9 44 Capricorni -1.9 mag (1st) to -1.9 mag (21st)
- Saturn- In eastern Leo Saturn's rings are inclined 3.8 deg towards Earth. Definitely a dramatic difference from last year! 0.6 mag (1st) to 0.6 mag (21st)
- Uranus- In Aquarius 5.9 mag (1st) to 5.9 mag (21st)
- Neptune- In Capricorn 8.0 mag (1st) to 7.9 mag (21st)
- Ceresand Eta - Finder chart from the New Zealand RAS (RASNZ) great charts! Northern Hemisphere observers this time you get to flip the chart or stand on your head!

Comparative lengths of day and night
This month we will look for 10 objects, 8 open clusters in the southern milky way and a pair of galaxies, all are within reach of binoculars. The open clusters are easy binocular targets and most are visible with the naked eye. M81 and M82 are difficult binocular targets that offer a stunning telescopic view. (I'm trying to find out what has happened to the NGC/IC Project homepage. It has been a standard AAGG reference for 3 years but seems to have disappeared! If you have any information on this great site please let me know....until then the images will be from: "Messier45.com" )
- M41
- This cluster in Canis Major is visible as a hazy patch to the naked eye just below Sirius. M41 is resolvable in binoculars and appears fairly loose in telescopes at low power.
- M93
- This is a small fuzzy patch of light in Puppis, partially resolvable in binoculars. The hardest part of finding this cluster in binoculars is picking it out of a fairly rich region of the milky way. Use low power to examine this cluster and the surrounding richness in a telescope. Medium power provides a nice view of the cluster itself.
- M47
- A bright cluster in Puppis, easily visible as a hazy patch to the naked eye. Binoculars will show a large hazy patch with many stars resolvable. Telescopes show a fairly loose cluster with stars of wide variety of magnitudes.
- M46
- This cluster is right next to M47 and is also visible to the naked eye. In binoculars M46 appears as a large hazy patch with no stars resolvable, giving a nice contrast to M47. In telescopes at low powers this cluster evenly fills the eyepiece. While you are here go to medium or high power and look for the planetary nebula NGC2438. It will appear as a faint uneven ring, with a blue/green color.
- M50
- An open cluster in Monoceros. This is a small hazy patch in binoculars, partially resolvable. Like M93, the richness of the surrounding field is the only difficulty in finding this object. This is a fairly tight cluster at low power in a telescope.
- M48
- Moving on to Hydra, we find another naked eye cluster. M48 is a large fuzzy patch in binoculars, partially resolvable. Use low to medium power in your telescope for a spectacular view.
- M67
- In the southeast portion of Cancer is another open cluster, barely visible as a fuzzy patch to the naked eye. Binoculars show M67 as a large hazy patch of light, similar to M46. Use low power to resolve this large, rich cluster in a telescope.
- M44
- Known as the Praesepe or Beehive Cluster, this open cluster is easily visible to the naked eye as a large, fuzzy patch bigger than the moon. Binoculars or rich field telescopes provide the best view of M44.
- M81, M82
- This pair of galaxies in Ursa Major are very possible to see in binoculars, they look like a pair of fuzzy stars. Both galaxies will fit into the same low power telescope field. M81 will appear as a large oval gray patch of light. M82 is a pencil like streak of light next to and perpendicular to the long axis of M81.

Interesting Planet Pairing for 2009- December 31, 2008 - Jupiter and Mercury - After sunset a little more than one degree apart in Sagittarius. Pull out the binos and telescopes because Mercury will be a mere 15 arcminutes from the globular cluster M75. All three will be together in one field of view in most home binoculars.
- January 22nd - Venus and Uranus - After sunset 1.3 degrees apart a few days later on the 29th they are joined by a waxing crescent moon.
- February 23rd - Jupiter, Mars and Mercury - In the early morning sky just before sunrise the trio are in a space about 2 degrees wide. Binoculars will be helpful but beware the quickly rising Sun. The Moon, almost invisible, will be between Mars and the Sun.
- March 23rd - Mars, Moon, Neptune, and Jupiter - Makes a nice line-up in the morning sky with Neptune just off the tip of the waning crescent moon.
- April 21st - Venus, Mars, Uranus, waning crescent Moon, Neptune and Jupiter - all in the pre-dawn sky together. First the right triangle of Venus, Mars, and Uranus followed by the waning crescent Moon and then finally by Neptune and Jupiter. Mars will be a faint 1.41 mag so binoculars will be helpful. The next day, possible occultation of Venus by the Moon. Check the IOTA website for occultations in your area.
- May 25th - Jupiter and Neptune - Jupiter is less than 1/2 degree South of Neptune in the morning sky. If you have ever had problems finding Neptune this would be a good time to try, between now and June.
- June 19th - Venus and Mars - In the pre-dawn sky just south of a waning crescent Moon. Closer to the Sun is Mercury and the Pleiades.
- August 17th - Saturn and Mercury - Very close to the Sun low in the evening sky. Much better view for Southern viewers.
- September 3rd UT 4:43 - Jupiter hides its Galilean moons. Not until 2019 will all of Jupiter's Galilean moons orbit in such a way.
- September 4th - Saturn - Not exactly a pairing but the Earth will cross the plane of the rings from south to north making the rings invisible
- October 16th - Mercury, Venus, and Saturn - All lined up in the pre-dawn sky close to the horizon. A faint waning crescent is just south of the trio.
- December 24th - Jupiter and Neptune - Just after sunset Jupiter and Neptune sit side-by-side just north of delta Capricornus and east of the "42,44,45 Cap Wall"

Eclipses for 2009
January 26 - Annular Solar Eclipse ( see map, times, and animation!): The first solar eclipse of 2009 occurs at the Moon's ascending node in western Capricornus. An annular eclipse will be visible from a wide track that traverses the Indian Ocean and western Indonesia. A partial eclipse will be seen within the much larger path of the Moon's penumbral shadow, which includes the southern third of Africa, Madagascar, Australia except Tasmania, southeast India, Southeast Asia and Indonesia.
February 09 - Penumbral Lunar Eclipse ( see map, times): The first lunar eclipse of 2009 is one of four such events during the year. The first three eclipses are penumbral while the last (on Dec. 31) is partial. The Feb 09 event is the deepest penumbral eclipse of the year with a penumbral magnitude of 0.899. It will be easily visible to the naked eye as a dusky shading in the northern half of the Moon. The times of the major phases are listed below.
July 07 - Penumbral Lunar Eclipse ( see map, times.): July's penumbral eclipse is only of academic interest since the magnitude is just 0.156. Although the Moon will be above the horizon from most of Canada, the eclipse is so minor as to be completely invisible to the naked eye.
July 21-22 - Total Solar Eclipse ( see map, times, and animation!): To make up for the anemic lunar eclipse earlier in the month, a major total eclipse of the Sun occurs two weeks later. The path of the Moon's umbral shadow extends across India, China, a handful of Japanese islands and the South Pacific Ocean (Espenak and Anderson, 2008). A partial eclipse is seen within the much broader path of the Moon's penumbral shadow, which includes most of eastern Asia, Indonesia, and the Pacific Ocean.
August 05-06 - Penumbral Lunar Eclipse ( see map, times): A shallow penumbral eclipse occurs 15 days after the total solar eclipse. Since its magnitude is only 0.402, it will not be visible to the naked eye.
December 31 - Penumbral Lunar Eclipse ( see map, times): The last eclipse of 2009 occurs on New Year's Eve. This minor partial lunar eclipse takes place in Gemini, and is visible primarily from the Eastern Hemisphere (Figure 8). Greatest eclipse takes place at 19:23 UT when the eclipse magnitude will reach 0.0763.

Shower: named for the constellation or closest star within a constellation where the radiant is located at maximum activity.
Activity Period: the dates when the ZHR (Zenith Hourly Rates) are equal to or greater than one.
Maximum: the date on which the maximum activity is expected to occur.
S.L.: the equivalent solar longitude of the date of maximum activity. Solar longitude is measured in degrees (0-359) with 0 occurring at the exact moment of the spring equinox, 90 at the summer solstice, 180 at the autumnal equinox, and 270 at the winter solstice.
Radiant: the area in the sky where shower meteors seem to appear from. This position is given in right ascension (celestial longitude) and declination (celestial latitude).
Velocity: the velocity at which shower meteors strike the Earth's atmosphere. The velocity depends on the angle meteoroids (meteors in space) intersect the Earth. Meteoroids orbiting in the opposite direction of the Earth and striking the atmosphere head-on are much faster than those orbiting in the same direction as the Earth. This velocity is measured in kilometers per second.
r: The Population Index, An estimate of the ratio of the number of meteors in subsequent magnitude classes. Simply stated: the lower the "r" value, the resulting overall mean magnitude of each shower will be brighter. "r" usually ranges from 2.0 (bright) to 3.5 (faint).
ZHR: Zenith Hourly Rate, the average maximum number of shower meteors visible per hour if the radiant is located exactly overhead and the limiting magnitude equals +6.5. Actual counts rarely reach this figure as the zenith angle of the radiant is usually less and the limiting magnitude is usually lower. ZHR is a useful tool when comparing the actual observed rates between individual observers as it sets observing conditions for all to the same standards.
Class: A scale developed by Robert Lunsford to group meteor showers by their intensity:
Class I: the strongest annual showers with ZHR's normally ten or better.
Class II: reliable minor showers with ZHR's normally three or better.
Class III: showers with widely variable rates. They may be strong one year and totally inactive the next.
Class IV: weak minor showers with ZHR's rarely exceeding three. The study of these showers is best left to experienced observers who use plotting and angular velocity estimates to determine shower association. Observers with less experience are urged to limit their shower associations to showers with a rating of I to III. These showers are also good targets for video and photographic work.
Moon: the age of the moon in days where 0 is new, 7 is first quarter, 14 is full, and 21 is last quarter. Meteor activity is best seen in the absence of moonlight so showers reaching maximum activity when the moon is less than 10 days old or more than 25 are much more favorably observed than those situated closer to the full moon.

Comparative lengths of
day and night
This month we
will look for 10 objects, 8 open clusters in the southern milky way and a pair
of galaxies, all are within reach of binoculars. The open clusters are easy
binocular targets and most are visible with the naked eye. M81 and M82 are
difficult binocular targets that offer a stunning telescopic view.
(I'm trying to find out what has happened to the NGC/IC Project homepage. It
has been a standard AAGG reference for 3 years but seems to have disappeared! If
you have any information on this great site please let me know....until then the
images will be from: "Messier45.com" )
- M41
- This cluster in Canis Major is visible as a hazy patch to the naked eye just
below Sirius. M41 is resolvable in binoculars and appears fairly loose in
telescopes at low power.
- M93
- This is a small fuzzy patch of light in Puppis, partially resolvable in
binoculars. The hardest part of finding this cluster in binoculars is picking it
out of a fairly rich region of the milky way. Use low power to examine this
cluster and the surrounding richness in a telescope. Medium power provides a
nice view of the cluster itself.
- M47
- A bright cluster in Puppis, easily visible as a hazy patch to the naked eye.
Binoculars will show a large hazy patch with many stars resolvable. Telescopes
show a fairly loose cluster with stars of wide variety of magnitudes.
- M46
- This cluster is right next to M47 and is also visible to the naked eye. In
binoculars M46 appears as a large hazy patch with no stars resolvable, giving a
nice contrast to M47. In telescopes at low powers this cluster evenly fills the
eyepiece. While you are here go to medium or high power and look for the
planetary nebula NGC2438. It will appear as a faint uneven ring, with a
blue/green color.
- M50
- An open cluster in Monoceros. This is a small hazy patch in binoculars,
partially resolvable. Like M93, the richness of the surrounding field is the
only difficulty in finding this object. This is a fairly tight cluster at low
power in a telescope.
- M48
- Moving on to Hydra, we find another naked eye cluster. M48 is a large fuzzy
patch in binoculars, partially resolvable. Use low to medium power in your
telescope for a spectacular view.
- M67
- In the southeast portion of Cancer is another open cluster, barely visible
as a fuzzy patch to the naked eye. Binoculars show M67 as a large hazy patch of
light, similar to M46. Use low power to resolve this large, rich cluster in a
telescope.
- M44
- Known as the Praesepe or Beehive Cluster, this open cluster is easily
visible to the naked eye as a large, fuzzy patch bigger than the moon.
Binoculars or rich field telescopes provide the best view of M44.
- M81, M82
- This pair of galaxies in Ursa Major are very possible to see in binoculars,
they look like a pair of fuzzy stars. Both galaxies will fit into the same low
power telescope field. M81 will appear as a large oval gray patch of light. M82
is a pencil like streak of light next to and perpendicular to the long axis of
M81.

Space Weather News for Feb. 23, 2009
http://spaceweather.com
COSMIC COINCIDENCE: What are the odds? On Tuesday, Feb. 24th, Saturn and Comet Lulin will converge in the constellation Leo only 2 degrees apart. At the same time, Comet Lulin
will be making its closest approach to Earth--the comet at its best!--
while four of Saturn's moons transit the disk of the ringed planet in
view of backyard telescopes. Oh, and the Moon will be New, providing dark skies for anyone who wishes to see the show.
The best time to look is around 1 a.m. Tuesday morning
(your local time) when the planet-comet combo ascend high in the
southern sky. To the unaided eye, Comet Lulin looks like a faint patch
of gas floating next to golden Saturn. Point your backyard telescope at
that patch and you will see a lovely green comet with a double tail.
Visit http://spaceweather.com for full coverage including photos, sky maps, and a live webcast.
Geographic
Notes: Comet Lulin is visible from all parts of the globe--all
longitudes and both hemispheres. Directions are reversed in the southern hemisphere; there the comet is located in the northern sky
around 1 am. Saturn is globally visible, too, but the special
quadruple transit of Saturn's moons starting around 3 a.m. PST on Feb.
24th is visible only to observers around the Pacific Rim. Details may
be found here: http://science.nasa.gov/headlines/y2009/19feb_quadrupletransit.htm - Astronomy a Go Go! February Sky Tour

Planets for February 2009
This year will be a morning viewing year but we still have bright Venus in
the early evening and Saturn for late night viewers!
Feb Morning
Planets (Feb 22nd) (click image to enlarge)
- Mercury- Now a morning planet, Mercury starts the month further away
from the Sun that the other two morning planets, Jupiter and Mars, and its angle
favors the S.hemisphere. Look for greatest elongation on the 13th. Mercury has
several close pairing this month with Jupiter on the 20th and Mars on the 24th.
By the 1st of March Mercury will neck-and-neck with Mars. 0.6 mag (1st) to 0.0
mag (21st)
- Venus- Venus has been distancing herself from the Sun for months, a
sparkling beacon in the early evening sky, even shining through the clouds from
time to time. Having reached greatest elongation on the Jan 14, a full 47 deg
east of the Sun, Venus begins her descent back towards the Sun. She was paired
nicely with the moon at the beginning of the month and will be again at the end
of the month with the next waxing crescent. RASC Observing guides recommend
watching for rare green and blue flashes as Venus sets through strong inversion
layers (possibly the only good thing about inversion layers!) Make sure you
share Venus with your friends and let them see the wonderful 'phases' she shares
with our Moon. -4.4 mag (1st) to -4.5 mag (21st)
- Mars- Has moved into the morning sky this month and will slowly crawl
away from the Sun all month. Start looking later in the month when on the 24th
it is paired with Mercury. 1.3 (1st) to 1.3 mag (21st)
- Jupiter- Still too close to the Sun at the beginning of the month. By
mid-month Jupiter will start to stand out in the pre-dawn sky on a flat horizon
growing stronger towards the end of the month and into March -1.9 mag (1st) to
-1.9 mag (21st)
- Saturn- In eastern Leo Saturn's rings are inclined 1.74 beg towards
Earth and will be at opposition on March 8th 0.9 mag (1st) to 0.9 mag (21st)
- Uranus- In Aquarius 5.9 mag (1st) to 5.9 mag (21st)

** "A descriptive parameter dubbed "illuminated extent" is proposed, defined
as the total solid angle subtended, from an astronomer's view, by the
illuminated portion of an object. A celestial body exhibiting wide variance in
both phase and angular size - an inferior planet primarily - is well
characterized by this parameter, for its peak value denotes when the luminous
image maximally covers a telescope's focal surface, a prime viewing
circumstance. " Gingrich, M Strolling Astron., Vol. 42, No. 1, p. 18 - 22

Wahoo! This
month has objects which are big, bright and easy to find!
(I'm trying to find out what has happened to the NGC/IC Project homepage. It
has been a standard AAGG reference for 3 years but seems to have disappeared! If
you have any information on this great site please let me know....until then the
images will be from: "Messier45.com" )
- M1
- The Crab nebula is a supernova remnant in Taurus. It is a hazy patch in small
telescopes, large scopes can resolve some detail. It is difficult but possible
to see in binoculars.
- M45 -
The Pleiades are a large open cluster in Taurus. Easy to resolve six stars naked
eye. Binoculars provide the best view. Large telescopes can show some
nebulosity.
- M35,
M37, M36,
M38
- A series of open clusters in the winter milky way. M35 is in Gemini, the
others are in Auriga. All can be seen naked eye as faint fuzzy stars, binoculars
reveal fuzzy patches, low power telescopes can resolve these rich clusters.
- M42 (seen here
with M43), M43
- M42 is the great Orion Nebula. It can be seen as small fuzzy patch naked eye.
Binoculars show some detail, and the view is superb in most any scope. M43 is a
small region of nebulosity next to M42, and probably requires the use of a
telescope to view. Use low to moderate powers for the best view of this pair.
- M78 - A small emission
nebula in Orion, a tough binocular object. Best viewed in a telescope at
moderate powers.
- M79 - One of the
smallest and dimmest globular clusters in the catalog. A tough binocular object
in Lepus, best viewed in a telescope at moderate powers.

Interesting Planet Pairing for 2009
- December 31, 2008 - Jupiter and Mercury - After sunset a
little more than one degree apart in Sagittarius. Pull out the binos and
telescopes because Mercury will be a mere 15 arcminutes from the globular
cluster M75. All three will be together in one field of view in most home
binoculars.
- January 22nd - Venus and Uranus - After sunset 1.3 degrees
apart a few days later on the 29th they are joined by a waxing crescent moon.
- February 23rd - Jupiter, Mars and Mercury - In the early
morning sky just before sunrise the trio are in a space about 2 degrees wide.
Binoculars will be helpful but beware the quickly rising Sun. The Moon, almost
invisible, will be between Mars and the Sun.
- March 23rd - Mars, Moon, Neptune, and Jupiter - Makes a nice
line-up in the morning sky with Neptune just off the tip of the waning crescent
moon.
- April 21st - Venus, Mars, Uranus, waning crescent Moon, Neptune
and Jupiter - all in the pre-dawn sky together. First the right triangle of
Venus, Mars, and Uranus followed by the waning crescent Moon and then finally by
Neptune and Jupiter. Mars will be a faint 1.41 mag so binoculars will be
helpful. The next day, possible occultation of Venus by the Moon. Check the IOTA
website for occultations in your area.
- May 25th - Jupiter and Neptune - Jupiter is less than 1/2
degree South of Neptune in the morning sky. If you have ever had problems
finding Neptune this would be a good time to try, between now and June.
- June 19th - Venus and Mars - In the pre-dawn sky just south of
a waning crescent Moon. Closer to the Sun is Mercury and the Pleiades.
- August 17th - Saturn and Mercury - Very close to the Sun low
in the evening sky. Much better view for Southern viewers.
- September 3rd UT 4:43 - Jupiter hides its Galilean moons. Not
until 2019 will all of Jupiter's Galilean moons orbit in such a way.
- September 4th - Saturn - Not exactly a pairing but the Earth
will cross the plane of the rings from south to north making the rings invisible
- October 16th - Mercury, Venus, and Saturn - All lined up in
the pre-dawn sky close to the horizon. A faint waning crescent is just south of
the trio.
- December 24th - Jupiter and Neptune - Just after sunset
Jupiter and Neptune sit side-by-side just north of delta Capricornus and east of
the "42,44,45 Cap Wall"

Eclipses for 2009
January 26 - Annular Solar Eclipse ( see map,
times, and animation!): The first
solar eclipse of 2009 occurs at the Moon's ascending node in western
Capricornus. An annular eclipse will be visible from a wide track that traverses
the Indian Ocean and western Indonesia. A partial eclipse will be seen within
the much larger path of the Moon's penumbral shadow, which includes the southern
third of Africa, Madagascar, Australia except Tasmania, southeast India,
Southeast Asia and Indonesia.
February 09 - Penumbral Lunar Eclipse ( see map,
times): The first lunar eclipse of 2009 is one of four such events during
the year. The first three eclipses are penumbral while the last (on Dec. 31) is
partial. The Feb 09 event is the deepest penumbral eclipse of the year with a
penumbral magnitude of 0.899. It will be easily visible to the naked eye as a
dusky shading in the northern half of the Moon. The times of the major phases
are listed below.
July 07 - Penumbral Lunar Eclipse ( see map,
times.): July's penumbral eclipse is only of academic interest since the
magnitude is just 0.156. Although the Moon will be above the horizon from most
of Canada, the eclipse is so minor as to be completely invisible to the naked
eye.
July 21-22 - Total Solar Eclipse ( see map,
times, and animation!): To make up
for the anemic lunar eclipse earlier in the month, a major total eclipse of the
Sun occurs two weeks later. The path of the Moon's umbral shadow extends across
India, China, a handful of Japanese islands and the South Pacific Ocean (Espenak
and Anderson, 2008). A partial eclipse is seen within the much broader path of
the Moon's penumbral shadow, which includes most of eastern Asia, Indonesia, and
the Pacific Ocean.
August 05-06 - Penumbral Lunar Eclipse ( see map,
times): A shallow penumbral eclipse occurs 15 days after the total solar
eclipse. Since its magnitude is only 0.402, it will not be visible to the naked
eye.
December 31 - Penumbral Lunar Eclipse ( see map,
times): The last eclipse of 2009 occurs on New Year's Eve. This minor
partial lunar eclipse takes place in Gemini, and is visible primarily from the
Eastern Hemisphere (Figure 8). Greatest eclipse takes place at 19:23 UT when the
eclipse magnitude will reach 0.0763.

Information and Table Template Courtesy The American Meteor Society, International Meteor Organization, and Meteors Online.
Shower: named for the constellation or closest star within a
constellation where the radiant is located at maximum activity.
Activity Period: the dates when the ZHR (Zenith Hourly Rates) are
equal to or greater than one.
Maximum: the date on which the maximum activity is expected to occur.
S.L.: the equivalent solar longitude of the date of maximum
activity. Solar longitude is measured in degrees (0-359) with 0 occurring at the
exact moment of the spring equinox, 90 at the summer solstice, 180 at the
autumnal equinox, and 270 at the winter solstice.
Radiant: the area in the sky where shower meteors seem to appear from.
This position is given in right ascension (celestial longitude) and
declination (celestial latitude).
Velocity: the velocity at which shower meteors strike the Earth's
atmosphere. The velocity depends on the angle meteoroids (meteors in space)
intersect the Earth. Meteoroids orbiting in the opposite direction of the Earth
and striking the atmosphere head-on are much faster than those orbiting in the
same direction as the Earth. This velocity is measured in kilometers per second.
r: The Population Index, An estimate of the ratio of the number
of meteors in subsequent magnitude classes. Simply stated: the lower the "r"
value, the resulting overall mean magnitude of each shower will be brighter. "r"
usually ranges from 2.0 (bright) to 3.5 (faint).
ZHR: Zenith Hourly Rate, the average maximum number of shower
meteors visible per hour if the radiant is located exactly overhead and the
limiting magnitude equals +6.5. Actual counts rarely reach this figure as the
zenith angle of the radiant is usually less and the limiting magnitude is
usually lower. ZHR is a useful tool when comparing the actual observed rates
between individual observers as it sets observing conditions for all to the same
standards.
Class: A scale developed by Robert Lunsford to group meteor showers by
their intensity:
Class I: the strongest annual showers with ZHR's normally ten or
better.
Class II: reliable minor showers with ZHR's normally three or better.
Class III: showers with widely variable rates. They may be strong one
year and totally inactive the next.
Class IV: weak minor showers with ZHR's rarely exceeding three. The
study of these showers is best left to experienced observers who use plotting
and angular velocity estimates to determine shower association. Observers with
less experience are urged to limit their shower associations to showers with a
rating of I to III. These showers are also good targets for video and
photographic work.
Moon: the age of the moon in days where 0 is new, 7 is first quarter,
14 is full, and 21 is last quarter. Meteor activity is best seen in the absence
of moonlight so showers reaching maximum activity when the moon is less than 10
days old or more than 25 are much more favorably observed than those situated
closer to the full moon.

Planets for January 2009
This year will be a morning viewing year but we still have bright Venus in the early evening and Saturn for late night viewers!
Early January Evening Planets (click image to enlarge)
Late January Evening Planets (click image to enlarge)
- Mercury- Starts the year close to Jupiter in the evening twilight. The further south you
are the easier it is to pick up this pair against the glowing horizon. Mercury reaches greatest elongation on the 4th before
racing back towards the sun (passing Jupiter again) reaching inferior conjunction on the 20th. By the end of the
month Mercury is with Mars and Jupiter in the morning, pre-dawn sky. They will all be quite faint, low for northern observers but
better as you go further south. -0.7 mag (1st) to 5.1 mag (21st)
- Venus- Venus has been distancing herself from the Sun for months, a sparkling beacon in the early evening sky, even
shining through the clouds from time to time. She reaches greatest elongation on the 14th, a full 47 deg east of the Sun.
On the 30th look for a pretty pairing with the crescent Moon. -4.2 mag (1st) to -4.3 mag (21st)
- Mars- Mars reached conjunction with the Sun on Dec 5th, and is slowly drifting into the morning sky. Mars
will play hide and seek with Mercury and Jupiter later in the month but will really start to become visible later
in February. 1.3 (1st) to 1.3 mag (21st)
- Jupiter- Is paired up nicely with Mercury as the year starts but quickly slides into the
glare of the Sun reaching conjunction on the 24th. Look for the return of the King to the pre-dawn sky in February. -1.9 mag (1st) to -1.9 mag (21st)
- Saturn- Saturn has been our "planet of the night" and those rings are continuing to flatten out. Saturn spends most
of the year in Leo before sliding into Virgo in September. With the rings at a close tilt of .81 deg. Although there are those who mourn
the shallow ring angle others will be using the reduction of glare to chase after Saturn's moons. (See the RASC Observing Challenge for 2009)
0.9 mag (1st) to 0.9 mag (21st)
- Uranus- In Aquarius 5.9 mag (1st) to 5.9 mag (21st)
- Neptune- In Capricorn 8.0 mag (1st) to 8.0 mag (21st)

Comparative lengths of day and night
This month has two of my personal Messier thorns; M77 and M74. Those two are offset by a favorite; the Little Dumbell.
You will need binoculars and a telescope to fully enjoy the January Messier objects.
- M33
This is a very large (about the size of the full moon) face on spiral galaxy in the constellation Triangulum. The total light from M33 is about magnitude 5.3, but when spread out over its large area it yields a very low surface brightness. The best and easiest views of M33 can be found with a pair of binoculars. Look for a large, round hazy patch of light with little detail at first glance. M33 can be glimpsed with the naked eye in dark clear skies. Finding M33 in a telescope can be a challenge because of its size. Use the widest field eyepiece you have and look for a change in light level to identify the galaxy.
- M103
This is a fairly small, sparse open cluster in Cassiopeia. Look for a tight group of stars in binoculars, being careful not to mistake it for several other clusters in the same area. Through a telescope the cluster is very sparse, four bright stars amidst the slight glow of much fainter companions.
- M52
This rich open cluster in Cassiopeia is fairly easy to see in binoculars as a faint smudge of light. A small to mid telescope will begin to resolve this cluster. Look for a triangular patch of light with some stars clearly resolved, but most of the cluster members provide only a hint of graininess.
- M76
Known as the little dumbell, this planetary nebula in Perseus is one of the dimmest objects in the Catalog. Look for a small, faint, oblong patch of light. Not a very obvious object, if you don't see it at first try varying magnifications in an attempt to bring it out. Fortunately M76 is located near a bright star which aids in locating the correct field to search.
- M34
This is a large and bright, but sparse open cluster located in Perseus. Visible as a faint patch of light to the naked eye, it is very obvious and easy to resolve in binoculars. In fact, binoculars provide a better view of this cluster than most telescopes.
- M74
This galaxy in Pisces is a smaller and fainter version of M33, a face on spiral galaxy with low surface brightness. M74 is arguably the most difficult object to find in the Catalog. You will need very dark, clear skies to easily see it, anything less than perfect conditions will make M74 nearly impossible to find. Look for a very faint fuzzy star, which is the bright central condensation, surrounded by a very faint glow. Try all of your tricks on this one; star hop to the correct field, try varying magnification, tap the scope to detect the galaxy through its motion. If all of the above fail, try again another night or seek darker skies.
- M77
This is a small faint galaxy in Cetus. Possible to see in binoculars, but very difficult, look for a faint fuzzy star. Through a telescope look for a fuzzy, oval shaped patch of light, bright in the center, fading towards the edges.

Interesting Planet Pairing for 2009
- December 31, 2008 - Jupiter and Mercury - After sunset a little more than one degree apart in Sagittarius. Pull out the binos
and telescopes because Mercury will be a mere 15 arcminutes from the globular cluster M75. All three will be together in
one field of view in most home binoculars.
- January 22nd - Venus and Uranus - After sunset 1.3 degrees apart a few days later on the 29th they are joined by a waxing crescent moon.
- February 23rd - Jupiter, Mars and Mercury - In the early morning sky just before sunrise the trio are in a space about 2 degrees wide.
Binoculars will be helpful but beware the quickly rising Sun. The Moon, almost invisible, will be between Mars and the Sun.
- March 23rd - Mars, Moon, Neptune, and Jupiter - Makes a nice line-up in the morning sky with Neptune just off the tip of the waning
crescent moon.
- April 21st - Venus, Mars, Uranus, waning crescent Moon, Neptune and Jupiter - all in the pre-dawn sky together. First the right triangle of
Venus, Mars, and Uranus followed by the waning crescent Moon and then finally by Neptune and Jupiter. Mars will be a faint 1.41 mag so binoculars
will be helpful. The next day, possible occultation of Venus by the Moon. Check the IOTA website for occultations in your area.
- May 25th - Jupiter and Neptune - Jupiter is less than 1/2 degree South of Neptune in the morning sky. If you have ever had
problems finding Neptune this would be a good time to try, between now and June.
- June 19th - Venus and Mars - In the pre-dawn sky just south of a waning crescent Moon. Closer to the Sun is Mercury and the Pleiades.
- August 17th - Saturn and Mercury - Very close to the Sun low in the evening sky. Much better view for Southern viewers.
- September 3rd UT 4:43 - Jupiter hides its Galilean moons. Not until 2019 will all of Jupiter's Galilean moons
orbit in such a way.
- September 4th - Saturn - Not exactly a pairing but the Earth will cross the plane of the rings from south to north making
the rings invisible
- October 16th - Mercury, Venus, and Saturn - All lined up in the pre-dawn sky close to the horizon. A faint waning crescent is
just south of the trio.
- December 24th - Jupiter and Neptune - Just after sunset Jupiter and Neptune sit side-by-side just north of delta Capricornus and east
of the "42,44,45 Cap Wall"

Eclipses for 2009
January 26 - Annular Solar Eclipse (
see map, times, and
animation!): The first solar eclipse of 2009 occurs at the Moon's ascending node in western Capricornus. An annular eclipse will be visible from a wide track that traverses the Indian Ocean and western Indonesia. A partial eclipse will be seen within the much larger path of the Moon's penumbral shadow, which includes the southern third of Africa, Madagascar, Australia except Tasmania, southeast India, Southeast Asia and Indonesia.
February 09 - Penumbral Lunar Eclipse (
see map, times): The first lunar eclipse of 2009 is one of four such events during the year. The first three eclipses are penumbral while the last (on Dec. 31) is partial. The Feb 09 event is the deepest penumbral eclipse of the year with a penumbral magnitude of 0.899. It will be easily visible to the naked eye as a dusky shading in the northern half of the Moon. The times of the major phases are listed below.
July 07 - Penumbral Lunar Eclipse (
see map, times.): July's penumbral eclipse is only of academic interest since the magnitude is just 0.156. Although the Moon will be above the horizon from most of Canada, the eclipse is so minor as to be completely invisible to the naked eye.
July 21-22 - Total Solar Eclipse (
see map, times, and
animation!): To make up for the anemic lunar eclipse earlier in the month, a major total eclipse of the Sun occurs two weeks later. The path of the Moon's umbral shadow extends across India, China, a handful of Japanese islands and the South Pacific Ocean (Espenak and Anderson, 2008). A partial eclipse is seen within the much broader path of the Moon's penumbral shadow, which includes most of eastern Asia, Indonesia, and the Pacific Ocean.
August 05-06 - Penumbral Lunar Eclipse (
see map, times): A shallow penumbral eclipse occurs 15 days after the total solar eclipse. Since its magnitude is only 0.402, it will not be visible to the naked eye.
December 31 - Penumbral Lunar Eclipse (
see map, times): The last eclipse of 2009 occurs on New Year's Eve. This minor partial lunar eclipse takes place in Gemini, and is visible primarily from the Eastern Hemisphere (Figure 8). Greatest eclipse takes place at 19:23 UT when the eclipse magnitude will reach 0.0763.

Information and Table Template Courtesy The American Meteor Society,
International Meteor Organization, and Meteors Online.
Shower: named for the constellation or closest star within a constellation where
the radiant is located at maximum activity.
Activity Period: the dates when the ZHR (Zenith Hourly Rates) are equal to or greater than one.
Maximum: the date on which the maximum activity is expected to occur.
S.L.: the equivalent solar longitude of the date of maximum activity.
Solar longitude is measured in degrees (0-359) with 0 occurring at the exact moment
of the spring equinox, 90 at the summer solstice, 180 at the autumnal equinox, and
270 at the winter solstice.
Radiant: the area in the sky where shower meteors seem to appear from. This position
is given in right ascension (celestial longitude) and declination (celestial latitude).
Velocity: the velocity at which shower meteors strike the Earth's atmosphere.
The velocity depends on the angle meteoroids (meteors in space) intersect the Earth.
Meteoroids orbiting in the opposite direction of the Earth and striking the atmosphere
head-on are much faster than those orbiting in the same direction as the Earth. This
velocity is measured in kilometers per second.
r: The Population Index, An estimate of the ratio of the number of meteors
in subsequent magnitude classes. Simply stated: the lower the "r" value, the resulting
overall mean magnitude of each shower will be brighter. "r" usually ranges from 2.0 (bright)
to 3.5 (faint).
ZHR: Zenith Hourly Rate, the average maximum number of shower meteors visible
per hour if the radiant is located exactly overhead and the limiting magnitude equals +6.5.
Actual counts rarely reach this figure as the zenith angle of the radiant is usually less and
the limiting magnitude is usually lower. ZHR is a useful tool when comparing the actual observed
rates between individual observers as it sets observing conditions for all to the same standards.
Class: A scale developed by Robert Lunsford to group meteor showers by their intensity:
Class I: the strongest annual showers with ZHR's normally ten or better.
Class II: reliable minor showers with ZHR's normally three or better.
Class III: showers with widely variable rates. They may be strong one year and totally
inactive the next.
Class IV: weak minor showers with ZHR's rarely exceeding three. The study of these
showers is best left to experienced observers who use plotting and angular velocity
estimates to determine shower association. Observers with less experience are urged to
limit their shower associations to showers with a rating of I to III. These showers
are also good targets for video and photographic work.
Moon: the age of the moon in days where 0 is new, 7 is first quarter, 14 is full,
and 21 is last quarter. Meteor activity is best seen in the absence of moonlight so
showers reaching maximum activity when the moon is less than 10 days old or more than 25
are much more favorably observed than those situated closer to the full moon.

Eclipses for 2009
January 26 - Annular Solar Eclipse (
see map, times, and
animation!): The first solar eclipse of 2009 occurs at the Moon's ascending node in western Capricornus. An annular eclipse will be visible from a wide track that traverses the Indian Ocean and western Indonesia. A partial eclipse will be seen within the much larger path of the Moon's penumbral shadow, which includes the southern third of Africa, Madagascar, Australia except Tasmania, southeast India, Southeast Asia and Indonesia.
February 09 - Penumbral Lunar Eclipse (
see map, times): The first lunar eclipse of 2009 is one of four such events during the year. The first three eclipses are penumbral while the last (on Dec. 31) is partial. The Feb 09 event is the deepest penumbral eclipse of the year with a penumbral magnitude of 0.899. It will be easily visible to the naked eye as a dusky shading in the northern half of the Moon. The times of the major phases are listed below.
July 07 - Penumbral Lunar Eclipse (
see map, times.): July's penumbral eclipse is only of academic interest since the magnitude is just 0.156. Although the Moon will be above the horizon from most of Canada, the eclipse is so minor as to be completely invisible to the naked eye.
July 21-22 - Total Solar Eclipse (
see map, times, and
animation!): To make up for the anemic lunar eclipse earlier in the month, a major total eclipse of the Sun occurs two weeks later. The path of the Moon's umbral shadow extends across India, China, a handful of Japanese islands and the South Pacific Ocean (Espenak and Anderson, 2008). A partial eclipse is seen within the much broader path of the Moon's penumbral shadow, which includes most of eastern Asia, Indonesia, and the Pacific Ocean.
August 05-06 - Penumbral Lunar Eclipse (
see map, times): A shallow penumbral eclipse occurs 15 days after the total solar eclipse. Since its magnitude is only 0.402, it will not be visible to the naked eye.
December 31 - Penumbral Lunar Eclipse (
see map, times): The last eclipse of 2009 occurs on New Year's Eve. This minor partial lunar eclipse takes place in Gemini, and is visible primarily from the Eastern Hemisphere (Figure 8). Greatest eclipse takes place at 19:23 UT when the eclipse magnitude will reach 0.0763.

Information and Table Template Courtesy The American Meteor Society, International Meteor Organization, and Meteors Online.
Shower: named for the constellation or closest star within a constellation where
the radiant is located at maximum activity.
Activity Period: the dates when the ZHR (Zenith Hourly Rates) are equal to or greater than one.
Maximum: the date on which the maximum activity is expected to occur.
S.L.: the equivalent solar longitude of the date of maximum activity.
Solar longitude is measured in degrees (0-359) with 0 occurring at the exact moment
of the spring equinox, 90 at the summer solstice, 180 at the autumnal equinox, and
270 at the winter solstice.
Radiant: the area in the sky where shower meteors seem to appear from. This position
is given in right ascension (celestial longitude) and declination (celestial latitude).
Velocity: the velocity at which shower meteors strike the Earth's atmosphere.
The velocity depends on the angle meteoroids (meteors in space) intersect the Earth.
Meteoroids orbiting in the opposite direction of the Earth and striking the atmosphere
head-on are much faster than those orbiting in the same direction as the Earth. This
velocity is measured in kilometers per second.
r: The Population Index, An estimate of the ratio of the number of meteors
in subsequent magnitude classes. Simply stated: the lower the "r" value, the resulting
overall mean magnitude of each shower will be brighter. "r" usually ranges from 2.0 (bright)
to 3.5 (faint).
ZHR: Zenith Hourly Rate, the average maximum number of shower meteors visible
per hour if the radiant is located exactly overhead and the limiting magnitude equals +6.5.
Actual counts rarely reach this figure as the zenith angle of the radiant is usually less and
the limiting magnitude is usually lower. ZHR is a useful tool when comparing the actual observed
rates between individual observers as it sets observing conditions for all to the same standards.
Class: A scale developed by Robert Lunsford to group meteor showers by their intensity:
Class I: the strongest annual showers with ZHR's normally ten or better.
Class II: reliable minor showers with ZHR's normally three or better.
Class III: showers with widely variable rates. They may be strong one year and totally
inactive the next.
Class IV: weak minor showers with ZHR's rarely exceeding three. The study of these
showers is best left to experienced observers who use plotting and angular velocity
estimates to determine shower association. Observers with less experience are urged to
limit their shower associations to showers with a rating of I to III. These showers
are also good targets for video and photographic work.
Moon: the age of the moon in days where 0 is new, 7 is first quarter, 14 is full,
and 21 is last quarter. Meteor activity is best seen in the absence of moonlight so
showers reaching maximum activity when the moon is less than 10 days old or more than 25
are much more favorably observed than those situated closer to the full moon.

Saturn rising before midnight and only Mars is missing from the major planet
lineup.
Early December Evening Planets (click image to enlarge)
Late December Evening Planets (click image to enlarge)
- Mercury- Starts the month passing into the evening sky and by
mid-month appears in the evening twilight. By the end of the month look for
Mercury next to Jupiter in the evening twilight. -0.8 mag (1st) to -1.2 mag
(21st)

the end of the month. As 2009 dawns Jupiter sets in evening twilight. -2.1 mag
(1st) to -2.0 mag (21st)
- Saturn- By the middle of the month Saturn rises in before midnight
(in Leo). Look carefully at the rings as the inclination closes to 0.8 deg 1.0
mag (1st) to 1.0 mag (21st)
- Uranus- In Aquarius 5.8 mag (1st) to 5.8 mag (21st)
- Neptune- In Capricorn 7.9 mag (1st) to 7.9 mag (21st)

Comparative lengths of
day and night
This will
be a fairly easy month on the tour. We will view two small, but bright globular
clusters, two open star clusters, and the grandest galaxy in the sky along with
it's two companions. All of these objects are possible to find in binoculars,
most are fairly easy.
- M2 This is a small,
bright globular cluster in Aquarius. To find it in binoculars look for a fuzzy
star in a star poor field. A low power telescope field will show a round fuzzy
patch, brighter in the center and fading to the edge, in a field with no other
bright objects.
- M15 This globular
cluster in Pegasus is very similar to M2 in size and brightness, except it is
surrounded by several bright stars. Fairly easy to find in binoculars but the
best view is through a telescope at medium to high power.
- M29 This galactic
cluster is a small, sparse group of stars in Cygnus. It appears as a small fuzzy
patch amongst a rich star field in binoculars. A telescope will easily resolve
the members of this cluster. The shape of the cluster reminds me of the Pleiades
as viewed through binoculars.
- M39 Dark skies will
allow this large, bright cluster in Cygnus to be seen with the naked eye as a
hazy patch of light. Binoculars easily resolve this cluster into it's bright and
widely scattered members, and provide a better view than can be seen with most
telescopes.
- M31, M32, and M110 M31
is the famous Andromeda Galaxy, our closest galactic neighbor, and the largest,
brightest galaxy to be seen in the northern sky. The ability to see M31 with the
naked eye provides a good, modern day, test of the darkness of your skies. M31
is so large that binoculars provide the best view, allowing the entire galaxy to
be seen in one field of view. Look for an elongated patch of light, with a
bright, round central core. M32 is an elliptical companion galaxy to M31.
Through a telescope look for a slightly oval ball of fuzz in the same low power
field as the core of M31. M32 is very possible to find in binoculars as a star
like point of light. M110, Another elliptical companion galaxy to M31, lying on
the opposite side of the core as M32. Through a telescope look for a large, oval
patch of light. Although M110 is as bright as M32 it is much larger and thus has
a lower surface brightness making it a difficult object in light polluted skies.
M110 is a very difficult binocular object requiring dark transparent skies, and
trained eyes to have a chance at finding it.

Interesting Planet Pairing for 2008
- January (first two week) - Mars, Betelgeuse and Aldebaran -
Mars will be moving westward into this red triangle, pausing at the end of the
month and then returning to regular Eastward motion at the beginning of
February.
- February 1 (start watching in early January) - Jupiter and
Venus - Start this early in January with Jupiter just off the horizon and
watch as they creep closer and closer. On the 1st of Feb early in the morning,
about one hour before sunrise in the east, Jupiter and Venus are less than one
degree apart in the constellation Sagittarius. They will be outstanding and you
could imagine all sorts of symbolism that could be associated with this
conjunction.
- February 27 - Mercury and Venus - Rising just one hour before
the Sun in the East in the constellation Capricornus. Venus and Mercury will be
just over one degree apart and then Venus will speed off, with Mercury in hot
pursuit.
- March 24 - Mercury and Venus...again - Mercury catches up to
Venus again, this time less than one degree apart and in the constellation
Aquarius. They will also be rising above the horizon only a half hour before the
sun, so seeing them will be quite a challenge.
- July 10 - Mars and Saturn - In the constellation Leo
yellowish-white Saturn and reddish Mars will be less than one degree from each
other. The pair is still up two hours after sunset and are bright so it should
be easy to see.
- August 13 - Venus and Saturn - Less than one degree apart in
the constellation Leo. Venus will be the brighter of the two.
- August 14 (watch from 10-16th)- Venus, Mercury, and Saturn -
Just after sunset a triple conjunction! The three planets will be less than
three degrees apart in the constellation Leo and almost in a line. Venus will be
the highest and brightest Saturn the middle object and Mercury will be the
lowest of the three but surprisingly brighter than Saturn. If you want to make
this even more interesting look for Mars 16 degrees to the SW the trio.
- August 19-21 - Venus and Mercury - The two planets will be
about one degree apart for three days. VERY low on the western horizon at
sunset.
- September 11 (watch from 5-18)- Venus and Mars - Venus will
come right next to the Red Planet, with the two less than one degree apart
Mercury lying three and a half degrees away from the pair and shining brighter
than Mars. The whole group will set just one hour after sunset.
- December 1 - Venus and Jupiter - All within Sagittarius, the
two planets will be two degrees apart and they don't set until three hours after
sunset. As a bonus, a 15%-lit moon will lie three degrees away from Venus.
- December 31 - Jupiter and Mercury - After sunset a little more
than one degree apart in Sagittarius. Pull out the binos and telescopes because
Mercury will be a mere 15 arcminutes from the globular cluster M75. All three
will be together in one field of view in most home binoculars.

Eclipses for 2008
February 07 - Annular Solar Eclipse ( see
map, times, and animation!): The first
solar eclipse of 2008 occurs at the Moon's ascending node in Capricornus. An
annular eclipse will be visible from a wide track, that traverses Antarctica and
southern regions of the Pacific Ocean. A partial eclipse will be seen within the
much larger path of the Moon's penumbral shadow, which includes the southeastern
third of Australia, all of New Zealand and most of Antarctica.
August 1 - Total Solar Eclipse ( see
map, times, and animation!): On Friday,
2008 August 01, a total eclipse of the Sun is visible from within a narrow
corridor that traverses half the Earth. The path of the Moon's umbral shadow
begins in Canada and extends across northern Greenland, the Arctic, central
Russia, Mongolia, and China. A partial eclipse is seen within the much broader
path of the Moon's penumbral shadow, which includes northeastern North America,
most of Europe and Asia. Special website with extra information and links to
live eclipse webcasts can be found at the NASA
Eclipse Website for the August 1st Eclipse
February 20th - Total Lunar Eclipse ( see
map, times.): The first lunar eclipse of 2008 is perfectly placed for
observers throughout most of the Americas as well as western Europe. The eclipse
occurs at the Moon's descending node, midway between perigee and apogee. During
the eclipse, Saturn lies about 3Â northeast of the Moon and shines brightly (mv
= +0.2) because it is near opposition. Special website with live broadcast can
be found at the NASA
Eclipse Website
August 16 - Partial Lunar Eclipse ( see
map, times): The last eclipse of 2008 is a partial lunar eclipse at the
Moon's ascending node in Capricornus. It is visible primarily from the Eastern
Hemisphere as well as eastern South America

Comparative lengths of day and night
This month we have seven more objects for our Messier list.
These include four globular clusters, the largest and the smallest planetary nebulas in the catalog,
and a small oddity. Two of the objects are fairly easy in binoculars, while four others will require dark skies,
patience, and keen eyes to find.
- M57 - This smallest planetary nebula in the Messier Catalog is the famous Ring nebula
in the constellation Lyra. Low power telescope views show a very small blue/green disk, not much bigger than a star. Medium to high power
will magnify the size of the nebula while leaving the surrounding stars the same size, confirming you have found it. Can be seen in binoculars
as a faint star like point of light.
- M56 - Also in the constellation of Lyra we find our first globular cluster of the night.
In a telescope look for a small round ball of light, slightly brighter in the center. This is a difficult binocular object appearing as a small
fuzzy patch.
- M27 - Also known as the Dumbbell nebula, the largest planetary nebula in the Messier Catalog,
M27 lies in the constellation Vulpecula. Fairly easy to see in binoculars as a small hazy patch. In small to medium scopes it appears as a
rectangular patch of light. In large scopes it may even appear round in shape with a bright rectangular, or dumbbell shaped core.
- M71 - Lying in Sagitta, this globular cluster appears as a faint oval hazy patch of
light in a telescope. This is a very difficult but possible binocular object, requiring dark skies and trained eyes.
- M30 - This globular cluster in Capricornus is tough but very possible to see in
binoculars as a faint fuzzy star. Telescopes show a small fuzzy ball of light, bright in the center fading to the edges.
- M72 - This is a small faint globular cluster in Aquarius. Look for a faint oval
patch of light, gradually brighter towards the middle. A very difficult binocular object.
- M73 - This asterism is located near M72 in Aquarius. In a low power telescope view it
looks like a very small fuzzy patch of light at first glance. When stared at it reveals itself as a small collection of stars. Medium to high
power shows the view best described by Messier "cluster of three or four stars...containing very little nebulosity".

Interesting Planet Pairing for 2008
- January (first two week) - Mars, Betelgeuse and Aldebaran - Mars will be moving westward into this red triangle,
pausing at the end of the month and then returning to regular Eastward motion at the beginning of February.
- February 1 (start watching in early January) - Jupiter and Venus - Start this early in January with
Jupiter just off the horizon and watch as they creep closer and closer. On the 1st of Feb early in the morning, about one hour before
sunrise in the east, Jupiter and Venus are less than one degree apart in the constellation Sagittarius. They will be outstanding and you could imagine all sorts of symbolism that
could be associated with this conjunction.
- February 27 - Mercury and Venus - Rising just one hour before the Sun in the East in the constellation Capricornus.
Venus and Mercury will be just over one degree apart and then Venus will speed off, with Mercury in hot pursuit.
- March 24 - Mercury and Venus...again - Mercury catches up to Venus again, this time less than
one degree apart and in the constellation Aquarius. They will also be rising above the horizon only a half hour before the sun, so seeing
them will be quite a challenge.
- July 10 - Mars and Saturn - In the constellation Leo yellowish-white Saturn and reddish Mars will be less than one degree
from each other. The pair is still up two hours after sunset and are bright so it should be easy to see.
- August 13 - Venus and Saturn - Less than one degree apart in the constellation Leo.
Venus will be the brighter of the two.
- August 14 (watch from 10-16th)- Venus, Mercury, and Saturn - Just after sunset a triple conjunction! The three planets will be less than three
degrees apart in the constellation Leo and almost in a line. Venus will be the highest and brightest Saturn the middle object
and Mercury will be the lowest of the three but surprisingly brighter than Saturn. If you want to make this even more interesting
look for Mars 16 degrees to the SW the trio.
- August 19-21 - Venus and Mercury - The two planets will be about one degree apart for three days. VERY low on the western horizon at sunset.
- September 11 (watch from 5-18)- Venus and Mars - Venus will come right next to the Red Planet, with the two less than one
degree apart Mercury lying three and a half degrees away from the pair and shining brighter than Mars.
The whole group will set just one hour after sunset.
- December 1 - Venus and Jupiter - All within Sagittarius, the two planets will be two degrees apart and they don't set until three hours after sunset.
As a bonus, a 15%-lit moon will lie three degrees away from Venus.
- December 31 - Jupiter and Mercury - After sunset a little more than one degree apart in Sagittarius. Pull out the binos
and telescopes because Mercury will be a mere 15 arcminutes from the globular cluster M75. All three will be together in
one field of view in most home binoculars.

Planets for September 2008
Mercury and Saturn slip into the morning sky, Mars creeps closer to the Sun,
Venus is brilliant in the evening sky and the rest of the gang
- Mercury- Starts in Virgo moves to Leo. By the end of the month look
for little Mercury 4 deg from Spica in Virgo 2.6 mag (1st) to -0.4 mag (21st)
- Venus- In Libra. Much easier to see this month as she rises a little
higher each night. Brighter than Jupiter the two make nice finder 'stars' in the
early evening. On the 31st look for a slender crescent moon together with the
goddess of love and beauty. -3.8 mag (1st) to -3.8 mag (21st)
- Mars- In Virgo. Mars heads off to do battle with the Sun. Very low on
the horizon for southern viewers at the beginning of the month it is lost to
high northern latitudes, not to be seen again until 2009! 1.6 (1st) to 1.6 mag
(21st)
- Jupiter- In Sagittarius. Still a fantastic sight to see Jupiter
transits around sunset for northern viewers. Jupiter reaches its east quadrature
(90 deg east of the Sun) on the 6th. -2.3 mag (1st) to -2.2 mag (21st)
- Saturn- In Leo. Climbing higher in the morning sky northern latitude
views have their best views mid-month. 1.0 mag (1st) to 1.0 mag (21st)
- Uranus- In Aquarius 5.7 mag (1st) to 5.8 mag (21st)
- Neptune- In Capricorn 7.9 mag (1st) to 7.9 mag (21st)

Sliding
into October we complete our tour of the wonders in Sagittarius. Sixteen Messier
objects are found within the constellation of Sagittarius, we will seek the six
that remain to be seen on our tour. We will also search for three others just
north of Sagittarius in the Milky Way.
Our October tour includes two nebulae and the clusters that power them, four
open clusters, a star cloud, and lastly two globular clusters. All of these
objects are possible in binoculars, most are easy in even small binoculars.
Several of these are also possible naked eye objects.
M24 - This "object" is
actually a section of the Milky Way in Sagittarius. It is easily seen with the
naked eye as a fuzzy, oval patch about four times the size of the full moon. The
best views are through binoculars or rich field telescopes.
M25 - Just east of M24 in
Sagittarius we find this open cluster. Visible to the naked eye, M25 lies in the
same binocular field as M24. In binoculars it appears as a partially resolved
star cluster buried in faint nebulosity. A view through a telescope shows the
nebulosity is in fact many faint stars that are not resolved in small
instruments.
M18 - This
is a small open cluster just north of M24 in Sagittarius. In binoculars M18 is
easy to see as a small fuzzy patch of light in the same field of view as M24.
Telescopes reveal this cluster for what it is, a small, sparse collection of
fairly bright stars.
M17 - Just north of M18 and in
the same binocular field as M24 and M18 lies the Omega nebula. Possible to see
with the naked eye and easy with binoculars, this nebula appears as a small
faint patch of fuzz. A telescope will show the unique V shape nebulosity that
gives the cluster its name. The shape reminds me of a swan with two bright stars
that power the cluster embedded in the head and neck of the swan.
M16 - Continuing north of M17
we find another nebula in Serpens. To the naked eye and binoculars, this small
patch of haze is very similar in appearance to M17 which is in the same
binocular field of view. Through a telescope the M16 looks like a sparse open
cluster of stars surrounded by faint wisps of smoke.
M26 - Continuing to head north
through the Milky Way we find this open cluster in the constellation Scutum.
This is a difficult object to find in binoculars, but possible as a faint patch
of fuzz. Telescopes partially resolve this cluster and show several stars buried
in a faint glow from the unresolved stars.
M11 - Just north of M26 in
Scutum lies the Wild Duck Cluster. Possible to see with the naked eye,
binoculars show a small faint patch surrounding a bright star. Telescopes
resolve many of the stars in this very rich cluster.
M55 - Dipping back into
Sagittarius we find two more globular clusters waiting for us. The first is one
of the brightest and largest globulars in the catalogue. Possible to see naked
eye, it is an easy binocular object appearing as a bright fuzzy ball of light.
Telescopes show a round patch of light bright in the center and fading toward
the edges. Large aperatures are needed to resolve this globular.
M75 - The last object of the
month, and the last object to be visited in Sagittarius. In binoculars, M75 is
not too hard to see, look for a small fuzzy star. A telescope will show a small
fuzz ball with a bright center.

- February 27 - Mercury and Venus - Rising just one hour before
the Sun in the East in the constellation Capricornus. Venus and Mercury will be
just over one degree apart and then Venus will speed off, with Mercury in hot
pursuit.
- March 24 - Mercury and Venus...again - Mercury catches up to
Venus again, this time less than one degree apart and in the constellation
Aquarius. They will also be rising above the horizon only a half hour before the
sun, so seeing them will be quite a challenge.
- July 10 - Mars and Saturn - In the constellation Leo
yellowish-white Saturn and reddish Mars will be less than one degree from each
other. The pair is still up two hours after sunset and are bright so it should
be easy to see.
- August 13 - Venus and Saturn - Less than one degree apart in
the constellation Leo. Venus will be the brighter of the two.
- August 14 (watch from 10-16th)- Venus, Mercury, and Saturn -
Just after sunset a triple conjunction! The three planets will be less than
three degrees apart in the constellation Leo and almost in a line. Venus will be
the highest and brightest Saturn the middle object and Mercury will be the
lowest of the three but surprisingly brighter than Saturn. If you want to make
this even more interesting look for Mars 16 degrees to the SW the trio.
- August 19-21 - Venus and Mercury - The two planets will be
about one degree apart for three days. VERY low on the western horizon at
sunset.
- September 11 (watch from 5-18)- Venus and Mars - Venus will
come right next to the Red Planet, with the two less than one degree apart
Mercury lying three and a half degrees away from the pair and shining brighter
than Mars. The whole group will set just one hour after sunset.
- December 1 - Venus and Jupiter - All within Sagittarius, the
two planets will be two degrees apart and they don't set until three hours after
sunset. As a bonus, a 15%-lit moon will lie three degrees away from Venus.
- December 31 - Jupiter and Mercury - After sunset a little more
than one degree apart in Sagittarius. Pull out the binos and telescopes because
Mercury will be a mere 15 arcminutes from the globular cluster M75. All three
will be together in one field of view in most home binoculars.

Eclipses for 2008
February 07 - Annular Solar Eclipse ( see
map, times, and animation!): The first
solar eclipse of 2008 occurs at the Moon's ascending node in Capricornus. An
annular eclipse will be visible from a wide track, that traverses Antarctica and
southern regions of the Pacific Ocean. A partial eclipse will be seen within the
much larger path of the Moon's penumbral shadow, which includes the southeastern
third of Australia, all of New Zealand and most of Antarctica.
August 1 - Total Solar Eclipse ( see
map, times, and animation!): On Friday,
2008 August 01, a total eclipse of the Sun is visible from within a narrow
corridor that traverses half the Earth. The path of the Moon's umbral shadow
begins in Canada and extends across northern Greenland, the Arctic, central
Russia, Mongolia, and China. A partial eclipse is seen within the much broader
path of the Moon's penumbral shadow, which includes northeastern North America,
most of Europe and Asia. Special website with extra information and links to
live eclipse webcasts can be found at the NASA
Eclipse Website for the August 1st Eclipse
February 20th - Total Lunar Eclipse ( see
map, times.): The first lunar eclipse of 2008 is perfectly placed for
observers throughout most of the Americas as well as western Europe. The eclipse
occurs at the Moon's descending node, midway between perigee and apogee. During
the eclipse, Saturn lies about 3Â northeast of the Moon and shines brightly (mv
= +0.2) because it is near opposition. Special website with live broadcast can
be found at the NASA
Eclipse Website
August 16 - Partial Lunar Eclipse ( see
map, times): The last eclipse of 2008 is a partial lunar eclipse at the
Moon's ascending node in Capricornus. It is visible primarily from the Eastern
Hemisphere as well as eastern South America

Planets for September 2008
Southern and Equatorial viewers will have a splendid view of the Venus, Mars,
Mercury trio-triangle early in the month in Virgo SW of Porrima (Virgo's
southern shoulder). Best view of Mercury for the entire year. Those above 30 deg
North will struggle to pick out Venus and Mercury in the bright twilight evening
sky.
- Mercury- In Virgo. Best viewed by those in the South until mid-month.
By early October Mercury will be in inferior conjunction and returning to the
morning sky. 0.0 mag (1st) to 0.5 mag (21st)
- Venus- In Virgo. The brightest member of the Venus, Mars, and Mercury
trio look for outstanding conjunctions on the 11th and 12 as the goddess of love
pairs up with the god of war. Best for viewers south of 30 deg North -3.8 mag
(1st) to -3.8 mag (21st)
- Mars- In Virgo. In addition to the groupings and conjunctions listed
above, from the 15th-20th Spica joins the group for a lovely traveling quartet
1.7 (1st) to 1.7 mag (21st)
- Jupiter- In Sagittarius. Starts the month in retrograde (westward)
motion becoming stationary on the 8th and returns to proper motion. The best
planet show for the northern hemisphere -2.5 mag (1st) to -2.4 mag (21st)
- Saturn- In Leo. Starts the month in conjunction with the Sun but by
month's end early rising viewers will find it rising in the East about two hours
before the Sun. Look for Regulus and find Saturn just under 15 deg East. After
about 4 months without Saturn make sure you look at the rings and see how much
they have 'closed' or moved parallel to our perspective. On the 26th look for a
sliver of a waning crescent Moon near Regulus. 0.8 mag (1st) to 0.9 mag (21st)
- Uranus-In Aquarius all year. Use the finder charts above to help you
find Uranus, it is only a little smaller, optically, than Mars looks now. 5.7
mag (1st) to 5.7 mag (21st)
- Neptune-In Capricorn 7.8 mag (1st) to 7.8 mag (21st)

Comparative lengths of
day and night
This month our monthly Messier hits some big easy targets, eight more
globular clusters, all are possible in binoculars, and two of these are the
finest globulars which can be seen from northern locations.
Sagittarius is the home of many globular clusters which surround the center
of the Milky Way Galaxy. Seven of the these globulars appear in the Messier
catalog, we will be visiting five of them this month. When you complete the
search for these objects be sure to spend some time scanning this region with
binoculars or a telescope and see what other sights you can discover. I
guarantee you will not be disappointed.
- M13 - The great
globular cluster in Hercules is bright enough to be seen with naked eye and
typically the first GC found by amateur astronomers in the NH. Binoculars easily
show this cluster as a bright fuzzy ball. M13 is partially resolvable in small
aperture telescopes and becomes a fantastic swarm of tightly packed individual
stars through large scopes.
- M92 - Another globular
cluster in Hercules, M92 is easy to find in binoculars appearing slightly dimmer
and smaller than M13. As with M13 it is partially resolvable in small scopes and
is a fine sight in large instruments.
- M14 - A small, bright
globular cluster in Ophiuchus. It is a difficult binocular object, look for a
small fuzzy patch of light. Through a telescope M14 is an even patch of light,
the stars not resolvable except through large scopes.
- M22 - This is the other
great globular in our tour this month. Located just above the teapot asterism in
Sagittarius, M22 can be seen with no optical aid. M22 is easy to find in
binoculars, and easy to resolve in telescopes, with about the same
impressiveness as M13.
- M28 - Located near M22
in Sagittarius, this is a small bright globular. A tough binocular object, look
for a small fuzzy patch. Easily seen in a telescope, but requires large aperture
to resolve individual stars.
- M69, M70, M54 All of these are small
bright globular clusters laying along the bottom of the teapot in Sagittarius.
Very similar in appearance to M28, these are all tough binocular objects
requiring dark skies and possibly averted vision to see. M54 is slightly
brighter and appears more star like through binoculars than the other globulars.
These are all easily seen in telescopes, though not easily resolvable.

Interesting Planet Pairing for 2008
- January (first two week) - Mars, Betelgeuse and Aldebaran -
Mars will be moving westward into this red triangle, pausing at the end of the
month and then returning to regular Eastward motion at the beginning of
February.
- February 1 (start watching in early January) - Jupiter and
Venus - Start this early in January with Jupiter just off the horizon and
watch as they creep closer and closer. On the 1st of Feb early in the morning,
about one hour before sunrise in the east, Jupiter and Venus are less than one
degree apart in the constellation Sagittarius. They will be outstanding and you
could imagine all sorts of symbolism that could be associated with this
conjunction.
- February 27 - Mercury and Venus - Rising just one hour before
the Sun in the East in the constellation Capricornus. Venus and Mercury will be
just over one degree apart and then Venus will speed off, with Mercury in hot
pursuit.
- March 24 - Mercury and Venus...again - Mercury catches up to
Venus again, this time less than one degree apart and in the constellation
Aquarius. They will also be rising above the horizon only a half hour before the
sun, so seeing them will be quite a challenge.

yellowish-white Saturn and reddish Mars will be less than one degree from each
other. The pair is still up two hours after sunset and are bright so it should
be easy to see.
- August 13 - Venus and Saturn - Less than one degree apart in

- August 14 (watch from 10-16th)- Venus, Mercury, and Saturn -
Just after sunset a triple conjunction! The three planets will be less than
three degrees apart in the constellation Leo and almost in a line. Venus will be
the highest and brightest Saturn the middle object and Mercury will be the
lowest of the three but surprisingly brighter than Saturn. If you want to make
this even more interesting look for Mars 16 degrees to the SW the trio.
- August 19-21 - Venus and Mercury - The two planets will be
about one degree apart for three days. VERY low on the western horizon at
sunset.
- September 11 (watch from 5-18)- Venus and Mars - Venus will
come right next to the Red Planet, with the two less than one degree apart
Mercury lying three and a half degrees away from the pair and shining brighter
than Mars. The whole group will set just one hour after sunset.
- December 1 - Venus and Jupiter - All within Sagittarius, the
two planets will be two degrees apart and they don't set until three hours after

Planets for March 2008
- Mercury- reaches greatest elongation west on the 3rd. For southern
observers Mercury is at it best morning apparition until mid-March. Mercury is
visible all month brightening as it creeps back towards the Sun. Mercury will be
close to Venus for most of the month making it much easier to find than usual.
They are in close conjunction on the 23rd 0.1 mag (1st) to -0.1 mag (21st)
- Venus- in Capricorn is still preceding the Sun but Venus begins to
fade as it creeps into glow of the Sun. Paired up with Mercury for most of the
month those close to the equator will have a nice view of the pair. -3.8 mag
(1st) to -3.8 mag (21st)
- Mars- Crosses over into Gemini this month and continues to shrink
from 9" to 7", too small to show much detail in the average backyard telescope.
Mars will be close to M35 on the 10th and it is appropriate that Mars is visible
all night in the month which bears its name. Mars also shows a gibbous globe for
the next two months. 0.2 (1st) to 0.6 mag (21st)
- Jupiter- For Southern observers will have Jupiter rising after
midnight while those in the mid-northern latitudes. On the 30th use the nearly
last quarter Moon to try and spot Jupiter, sitting to the Moon's NE, during the
day. -2.0 mag (1st) to -2.1 mag (21st)
- Saturn- having reached opposition in February Saturn spend the month
in Leo. The tilt of Saturn's rings increases from 6.7 deg to 9.9 deg in early
May before beginning to close again at the end of 2008. 0.2 mag (1st) to 0.3 mag
(21st)
- Uranus-In Aquarius all year 5.9 mag (1st) to 5.9 mag (21st)
- Neptune-In Capricorn 8.0 mag (1st) to 8.0 mag (21st)

Comparative lengths of
day and night
The weekend of the 7-9th of March is a good 'first try' for a Messier
Marathon. This is a better for those of you further South and, if we get clouded
out then we have the 4-6th of April as a good back up date. The April date will
be the better of the two for mid-to higher Northern latitude views but don't
pass up on the chance in March if the weather is fair.
If you are looking for a good way to conquer the Virgo Cluster go to show #39. There
you will find lots of information on navigating the Virgo Cluster.
This month highlights 10 messier objects, most are within reach of
binoculars, and over half can be seen with the naked eye.
- M41 - This cluster is
visible as a hazy patch to the naked eye just below Sirius in Canis Major. M41
is resolvable in binoculars and appears fairly loose in telescopes at low power.
- M93 - This is a small
fuzzy patch of light in Puppis, partially resolvable in binoculars. The hardest
part of finding this cluster in binoculars is picking it out of a fairly rich
region of the Milky Way. Use low power to examine this cluster and the
surrounding richness in a telescope. Medium power provides a nice view of the
cluster itself.
- M47 - A bright cluster
in Puppis, easily visible as a hazy patch to the naked eye. Binoculars will show
a large hazy patch with many stars resolvable. Telescopes show a fairly loose
cluster with stars of wide variety of magnitudes.
- M46 - This cluster is
right next to M47 and is also visible to the naked eye. In binoculars M46
appears as a large hazy patch with no stars resolvable, giving a nice contrast
to M47. In telescopes at low powers this cluster evenly fills the eyepiece.
While you are here go to medium or high power and look for the planetary nebula
NGC2438. It will appear as a faint uneven ring, with a blue/green color.
- M50 - An open cluster
in Monoceros. This is a small hazy patch in binoculars, partially resolvable.
Like M93, the richness of the surrounding field is the only difficulty in
finding this object. This is a fairly tight cluster at low power in a telescope.
- M48 - Moving on to
Hydra, we find another naked eye cluster. M48 is a large fuzzy patch in
binoculars, partially resolvable. Use low to medium power in your telescope for
a spectacular view.
- M67 - In the southeast
portion of Cancer is another open cluster, barely visible as a fuzzy patch to
the naked eye. Binoculars show M67 as a large hazy patch of light, similar to
M46. Use low power to resolve this large, rich cluster in a telescope.
- M44 - Known as the
Praesepe or Beehive Cluster, this open cluster is easily visible to the naked
eye as a large, fuzzy patch bigger than the moon. Binoculars or rich field
telescopes provide the best view of M44.
- M81, M82 - This pair of galaxies in
Ursa Major are very possible to see in binoculars, they look like a pair of
fuzzy stars. Both galaxies will fit into the same low power telescope field. M81
will appear as a large oval gray patch of light. M82 is a pencil like streak of
light next to and perpendicular to the long axis of M81.

Interesting Planet Pairing for 2008
- January (first two week) - Mars, Betelgeuse and Aldebaran -
Mars will be moving westward into this red triangle, pausing at the end of the
month and then returning to regular Eastward motion at the beginning of
February.
- February 1 (start watching in early January) - Jupiter and
Venus - Start this early in January with Jupiter just off the horizon and
watch as they creep closer and closer. On the 1st of Feb early in the morning,
about one hour before sunrise in the east, Jupiter and Venus are less than one
degree apart in the constellation Sagittarius. They will be outstanding and you
could imagine all sorts of symbolism that could be associated with this
conjunction.
- February 27 - Mercury and Venus - Rising just one hour before
the Sun in the East in the constellation Capricornus. Venus and Mercury will be
just over one degree apart and then Venus will speed off, with Mercury in hot
pursuit.
- March 24 - Mercury and Venus...again - Mercury catches up to
Venus again, this time less than one degree apart and in the constellation
Aquarius. They will also be rising above the horizon only a half hour before the
sun, so seeing them will be quite a challenge.
- July 10 - Mars and Saturn - In the constellation Leo
yellowish-white Saturn and reddish Mars will be less than one degree from each
other. The pair is still up two hours after sunset and are bright so it should
be easy to see.
- August 13 - Venus and Saturn - Less than one degree apart in
the constellation Leo. Venus will be the brighter of the two.
- August 14 (watch from 10-16th)- Venus, Mercury, and Saturn -
Just after sunset a triple conjunction! The three planets will be less than
three degrees apart in the constellation Leo and almost in a line. Venus will be
the highest and brightest Saturn the middle object and Mercury will be the
lowest of the three but surprisingly brighter than Saturn. If you want to make
this even more interesting look for Mars 16 degrees to the SW the trio.
- August 19-21 - Venus and Mercury - The two planets will be
about one degree apart for three days. VERY low on the western horizon at
sunset.
- September 11 (watch from 5-18)- Venus and Mars - Venus will
come right next to the Red Planet, with the two less than one degree apart
Mercury lying three and a half degrees away from the pair and shining brighter
than Mars. The whole group will set just one hour after sunset.
- December 1 - Venus and Jupiter - All within Sagittarius, the
two planets will be two degrees apart and they don't set until three hours after
sunset. As a bonus, a 15%-lit moon will lie three degrees away from Venus.
- December 31 - Jupiter and Mercury - After sunset a little more
than one degree apart in Sagittarius. Pull out the binos and telescopes because
Mercury will be a mere 15 arcminutes from the globular cluster M75. All three
will be together in one field of view in most home binoculars.

Eclipses for 2008
February 07see
map, timesanimationAugust 1 - Total Solar Eclipse ( see
map, times, and animation!): On Friday,
2008 August 01, a total eclipse of the Sun is visible from within a narrow
corridor that traverses half the Earth. The path of the Moon's umbral shadow
begins in Canada and extends across northern Greenland, the Arctic, central
Russia, Mongolia, and China. A partial eclipse is seen within the much broader
path of the Moon's penumbral shadow, which includes northeastern North America,
most of Europe and Asia. Special website with extra information and links to
live eclipse webcasts can be found at the NASA
Eclipse Website for the August 1st Eclipse
February 20th - Total Lunar Eclipse ( see
map, times.): The first lunar eclipse of 2008 is perfectly placed for
observers throughout most of the Americas as well as western Europe. The eclipse
occurs at the Moon's descending node, midway between perigee and apogee. During
the eclipse, Saturn lies about 3Â northeast of the Moon and shines brightly (mv
= +0.2) because it is near opposition. Special website with live broadcast can
be found at the NASA
Eclipse Website
August 16 - Partial Lunar Eclipse ( see
map, times): The last eclipse of 2008 is a partial lunar eclipse at the
Moon's ascending node in Capricornus. It is visible primarily from the Eastern
Hemisphere as well as eastern South America

- Mercury- is at inferior conjunction on the 6th. It becomes visible to
southern observers in the morning twilight by mid-month. Late February to March
will be the best viewing of Mercury for the year for Southern observers. Mercury
climb up to meet Venus and on the 26th Mercury will be 1.3 deg N of Venus 1.9
mag (1st) to 0.6 mag (21st)
- Venus- Hopefully you have been watching Venus and Jupiter creep
closer throughout the end of January. On the 1st of February Venus is 0.6 deg N
of Jupiter. On the 4th the waning crescent moon shares the scene. Watch the rest
of the month as Venus pulls closer to the sun. On the 26th and 27th catch Venus
and Mercury stacked on the horizon just before sunrise. -3.8 mag (1st) to -3.8
mag (21st)
- Mars- Starts off the month still between the horns of Taurus and is
well placed high in the northern sky in early evening. It is heading back
towards the foot of Castor, and M35, but is official still in Taurus at the end
of the month. -0.6 (1st) to 0.0 mag (21st)
- Jupiter- Starts the month buddied up with Venus and by the 13th leads
a line up of Mercury, Venus and Jupiter with Jupiter furthest away from the sun.
-1.8 mag (1st) to -1.8 mag (21st)
- Saturn- In Leo all year Saturn reaches opposition on February 24. On
the 21st at 3:29 UT (convert to your time zone) during the total lunar eclipse
you should be able to pick out Saturn and Regulus once the Moon enters the Earth
umbra. Rises mid-evening at the beginning of February. The tilt of Saturn's
rings increases from 6.7 deg to 9.9 deg in early May before beginning to close
again at the end of 2008. 0.4 mag (1st) to 0.2 mag (21st)
- Uranus-In Aquarius all year 5.9 mag (1st) to 5.9 mag (21st)
- Neptune-In Capricorn 8.0 mag (1st) to 8.0 mag (21st)

Comparative lengths of
day and night
This month highlights 10 messier objects, most are within reach of
binoculars, and over half can be seen with the naked eye.
- M1 - The Crab nebula is
a supernova remnant in Taurus. It is a hazy patch in small telescopes, large
scopes can resolve some detail. It is difficult but possible to see in
binoculars.
- M45 - The Pleiades are
a large open cluster in Taurus. Easy to resolve six stars naked eye. Binoculars
provide the best view. Large telescopes can show some nebulosity.
- M35, M37, M36, M38 A series of open clusters
in the winter milky way. M35 is in Gemini, the others are in Auriga. All can be
seen naked eye as faint fuzzy stars, binoculars reveal fuzzy patches, low power
telescopes can resolve these rich clusters.
- M42 M43 M42 is the
great Orion Nebula. It can be seen as small fuzzy patch naked eye. Binoculars
show some detail, and the view is superb in most any scope. M43 is a small
region of nebulosity next to M42, and probably requires the use of a telescope
to view. Use low to moderate powers for the best view of this pair.
- M78 - A small emission
nebula in Orion, a tough binocular object. Best viewed in a telescope at
moderate powers.
- M79 - One of the
smallest and dimmest globular clusters in the catalog. A tough binocular object
in Lepus, best viewed in a telescope at moderate powers.

Eclipses for 2008
February 07 - Annular Solar Eclipse ( see
map, times, and animation!): The first
solar eclipse of 2008 occurs at the Moon's ascending node in Capricornus. An
annular eclipse will be visible from a wide track, that traverses Antarctica and
southern regions of the Pacific Ocean. A partial eclipse will be seen within the
much larger path of the Moon's penumbral shadow, which includes the southeastern
third of Australia, all of New Zealand and most of Antarctica.
August 1 - Total Solar Eclipse ( see
