Astronomical Highlights
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. 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 starlike through binoculars than the other globulars. These are all easily seen in telescopes, though not easily resolvable.

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...
