Comet C/2001 A2 (better known as "Comet LINEAR") makes its closest approach to Earth on Saturday, June 30th. Glowing at visual magnitude 4, Comet LINEAR is not spectacular like, e.g., Comet Hale-Bopp of 1997, but it will be easy to spot with the unaided eye. Astronomers have watched this comet intently in recent months as it repeatedly crumbled and brightened. The capricious snowball from the outer solar system could yet hold surprises for observers in the days and weeks ahead.
