Download this month's sky map!

Kym Thalassoudis does a wonderful job creating accurate and easy to use star maps every month! Visit his site at www.skymaps.com for skymaps and links to other useful astronomical sites. Also a great portal for astronomical gifts!

Northern hemisphere sky map
Southern hemisphere sky map

Those in the Southern Hemisphere should also visit James Barclay's site for a great tour of the Southern Hemisphere December sky.

Another great site for Southern Hemisphere viewers is the Royal Astronomical Society of New Zealand's Southern Hemisphere Calendar can be found at the RASNZ site
Ian Musgrave has a very handy Southern Hemisphere site called Southern Sky Watch.

Download "What's up 2007: 365 days of Skywatching" by Tammy Plotner, published by Universe Today (Faser Cain) it is a fantastic and it is free!

Planets for February 2007

Mercury The first week of February marks it's greatest elongation and better viewing. Mercury continues to creep closer to Venus until the 13th before heading back towards the sun from which it rarely strays. -0.9 mag (1st) to 4.4 mag (21st)

Venus Easy target at sunset and until half an hour after astronomical twilight. On the 7th at 13h UT use Venus to find Uranus 0.7 degrees S. -3.8 mag (1st) to - 3.8 mag (21st)

Mars Mars has moved into Sagitarrius and rising about 1.5 hours before the Sun towards the end of the month Mars moves into Capricorn with Neptune. 1.4 mag (1st) to 1.3 mag (21st)

Jupiter At the beginning of the month Jupiter is rising a few hours after midnight and by mid-month closer to midnight. Jupiter at -1.8 mag, spends the first 11 months of the year in Ophiuchus! -1.9 mag (1st) to -2.0 mag (21st)

Saturn spends the entire year in Leo and is the showpiece of the night time sky. Saturn is at opposition on the 10th rising at sunset opposite Venus and Mercury and transiting around midnight as Jupiter rises. 0.0 mag (1st) to 0.0 mag (21st)

Uranus Starts the month it is 1 deg E of Lambda on the 7th use Venus to find Uranus just 0.7 degrees N of Venus. 8.0 mag (1st) to 8.0 mag (21st)

Neptune will camp out in Capricorn all year long. Invisible as the Sun creeps into Capricorn Neptune is in conjunction with the sun on the 8th.

Key Dates for February 2007

Days and Times in UT (help with time)

Observations are for 8pm for the mid-northern latitudes and for 10pm for the mid-southern latitudes.

Monthly Messier*

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 Ã�¢ï¿½ï¿½ These are 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.
*Monthly Messier information gleaned from the Royal Astronomical Society of Canada, Moncton Centre Quebec and from the Astronomy Connection website.

Eclipse information from: NASA Eclipse Homepage, Eclipses Online (HM Nautical Almanac Office, UK in coordination with the U.S. Naval Observatory)

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.

Mark your calendar to look for...
  • Lyrids on April 23rd
  • 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.)
