Astronomical Highlights
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 (in image of 110) - 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 (in image of 110) - 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.

Astronomical Highlights for 2007Earth's major motions for 2007 Planet Positions for 2007 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. Eclipse information from: NASA Eclipse Homepage, Eclipses Online (HM Nautical Almanac Office, UK in coordination with the U.S. Naval Observatory)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...
