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)

*The time when the Sun reaches the point along the ecliptic where it crosses into the northern celestial hemisphere marking the start of spring in the Northern Hemisphere and autumn in the Southern Hemisphere.

**Reduced to a one sentence definition, Easter Sunday is calculated as the first Sunday after the first full moon which falls on or after the Vernal(March) Equinox. This year the full moon is ON the Vernal(March) equinox so Easter is the 23rd. (The earliest Easter could ever be is March 22 and the latest April 25)

Monthly Messier*

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.

2008 February 21 [ Lunar: Total ]

2008 August 01 [ Solar: Total ]

2008 August 16 [ Lunar: Partial ]

February 07see map, timesanimation

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 3° 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)

Planets for January 2008

• Mercury- visible in evening twilight higher and brighter as the month progresses. Mercury reaches its greatest elongation east on the 22nd (19deg) on the 23 (4UT) Mercury will be .3 deg North of a very dim Neptune -0.9 mag (1st) to -0.7 mag (21st)
• Venus- Venus is the queen of the morning all month, rising 3 hours before the Sun at the beginning of the month but only 2 hours before the sun at the end of the month. Watch Venus and Jupiter throughout the month as they get closer, about 1 deg a day, until the 31st when they are only 1 deg apart. -3.9 mag (1st) to -3.9 mag (21st)
• Mars- Just past its December opposition Mars is visible almost all night. Officially in Taurus it appears to be closer to the leg of Castor of Gemini the twins. Mars moves into a nice orange/red triangle with Betelgeuse and Aldebaran before becoming stationary on the 20th and returning to direct (eastward) motion for the rest of the month. -1.5 (1st) to -0.9 mag (21st)
• Ceres-
• Jupiter- Jupiter has been hiding behind the sun now reappears in the morning sky climbing higher in the sky. By mid-month Jupiter rises 9 deg above the horizon before sunrise, by the end of the month Jupiter and Venus are 1 deg apart. -1.8 mag (1st) to -1.8 mag (21st)
• Saturn- In Leo all year Saturn rises mid-evening at the beginning of January. 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. 0.7 mag (1st) to 0.6 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)

Planets for December 2007

• Mercury- very difficult to observe this month as it reaches superior conjunction on the 17th -0.8 mag (1st) to -1.2 mag (21st)
• Venus- In Virgo Venus is brilliant in the morning sky for both hemispheres all month. Sliding closer to the sun by months end it will be rising just a little over an hour before astronomical twilight. -4.1 mag (1st) to - 4.0 mag (21st)
• Mars- In Gemini Mars and Earth reach their closest approach on Dec 19th, is occulted by the Moon on the 23/24, on the 24th is at opposition rising near sunset, transits about midnight and sets near sunrise...how convenient! Earth and Mars will not be this close again until 2016 so it is worth your while to get out and see the 'Red Planet' as often as possible. By the end of the month Mars will have retrograded into Taurus. -1.3 Ultimate Mars list of links (1st) to -1.6 mag (21st)
• Ceres- reaches opposition on Nov. 9th brightening to magnitude 7.2 (see the finder chart below)
• Jupiter- In Sagittarius sets in the west-southwest at the end of twilight and by the second week is lost in the glare of the Sun. -1.8 mag (1st) to -1.8 mag (21st)
• Saturn- In Leo Saturn is at quadrature,when the planet's shadow on the rings is most prominent making the planet look 3D, on Dec 1st. On the 15th the rings are the least tilted from edgewise (6.6 deg) than they have been in a decade. On the 20th it begins its retrograde loop moving back towards Regulus. 0.7 mag (1st) to 0.6 mag (21st)
• Uranus-In Aquarius 5.7 mag (1st) to 5.8 mag (21st)
• Neptune-In Capricorn 7.9 mag (1st) to 7.8 mag (21st)

Eclipses for 2007

March 19 - partial solar eclipse (see map, times, and animation!): The first solar eclipse of 2007 occurs at the Moon's ascending node in Pisces and is visible from eastern Asia and parts of northern Alaska

September 11 - partial solar eclipse (see map, times, and animation): The last eclipse of 2007 is a partial solar eclipse at the Moon's descending node in southern Leo. Its visibility is confined to parts of South America, Antarctica and the South Atlantic

March 3-4 - total lunar eclipse (see map): The beginning of the umbral phase visible in the Arctic region, Africa, Europe, Asia except for extreme eastern region, most of Indonesia, western Australia, Queen Maud Land of Antarctica, extreme eastern South America, Greenland, the Indian Ocean, the South Atlantic Ocean, and the eastern North Atlantic Ocean; the end visible in Africa, Europe, western Asia, Queen Maud Land of Antarctica and Antarctic Peninsula, South America, eastern North America, Greenland, the Arctic region, the Atlantic Ocean, the western Indian Ocean, and the extreme eastern South Pacific Ocean.

August 28 - total lunar eclipse (see map): The beginning of the umbral phase visible in North America, South America except extreme east, Antarctica except for Enderby Land, New Zealand, eastern Australia, extreme northeastern Asia, the Pacific Ocean, and the western Atlantic Ocean; the end visible in New Zealand, Australia, most of Antarctica except Queen Maud Land, Indonesia, eastern Asia, western North America, the Pacific Ocean, and the southeastern Indian Ocean.

Meteor Showers for 2007

As luck would have it, all the major meteor showers reach their peaks in 2007 with the Moon out of the sky. Any of these showers can produce dozens of shooting stars each dark hour leading up to dawn.

• Perseids on August 13th
• Orionids on October 21st
• Leonids on November 18th
• Geminids on the night of December 13-14 (Meteor enthusiasts are keenly awaiting the Geminids in 2007 because their progenitor, the defunct comet Phaethon, precedes them in a flyby of Earth on December 10th.)

Planets for November 2007

• Mercury- In Virgo Mercury reaches greatest elongation west on Nov. 8th. This morning showing favors northern observers and at the beginning of the month will show as a thick crescent. Look low in the east-southeast through the end of November. Poor viewing for Southern viewers 0.8 mag (1st) to -0.7 mag (21st)
• Venus- Starts in Leo but after the first weekend crosses into Virgo with Mercury. Venus is brilliant in the morning sky and will be all month. On Nov.5th use the moon to find Venus during the day. -4.0 mag (1st) to - 4.1 mag (21st)
• Mars- In Gemini. Earth is slowly catching up to Mars so the red planet will continue to look larger through December when Earth and Mars are their closest approach. Nov. 15th Mars begins its retrograde loop within Gemini. -0.6 (1st) to -0.8 mag (21st)
• Ceres- reaches opposition on Nov. 9th brightening to magnitude 7.2 (see the finder chart below)
• Jupiter- In Ophiuchus sets in the west-southwest at the end of twilight for mid-Northern viewers by mid-month. Viewing is better as you move South. -1.9 mag (1st) to -1.8 mag (21st)
• Saturn- In Leo Saturn rises several hours before sunrise with Venus and Regulus in a nice little trio. Saturn is at quadrature,when the planet's shadow on the rings is most prominent making the planet look 3D, on Dec 1st 0.7 mag (1st) to 0.8 mag (21st)
• Uranus-In Aquarius 5.7 mag (1st) to 5.8 mag (21st)
• Neptune-In Capricorn 7.9 mag (1st) to 7.8 mag (21st)
