Looking for Comet Lulin
Feb. 24, 2009
Comet Lulin There's a weird, double-tailed comet in the night sky this week and it can be spotted with a pair of good binoculars, even through low-level light pollution. And in the beautifully clear, high-altitude atmosphere of the San Juan Mountains, even naked eye viewing is possible. But, you'll have to know exactly where to look. The chart at right should get you there - it shows the starry scene about 9 p.m. - but the viewing will actually get better later, after 10p.m., when the comet and its background rise higher.
The comet, formally known as "C/2007 N3 (Lulin)", was discovered at Lulin Observatory in Taiwan in July 2007. In telescopes and low-light images, it's showing both a dim gas tail and a dust-spike antitail pointing in nearly the opposite direction. Its current brightness is about magnitude 5.2.
How to Find It:
To locate the planet Saturn, watch the eastern horizon at twilight and early evening. Eventually, you will see two distinct points of light shining in the east-southeast sky. Regulus, the "heart star" of the Leo the Lion, rises first, followed shortly thereafter by a larger, brighter Saturn. The comet Lulin can be seen traveling close-by and in front of these two celestial objects. Sometime between midnight or 1:00 a.m., this cosmic trio will reach zenith - the highest point of their ascension - in the southern night sky. For those with telescopes, Saturn rings are just 2º from "edge on." Good luck and happy viewing!
