COMET TAIL: Exploding Comet 17P/Holmes continues to amaze onlookers. On Nov. 8th and 9th part of the comet’s blue tail broke away in view of many backyard telescopes. Visit http://spaceweather.com to see photos of the “disconnection event” and speculation about what might have caused it.

TAURID METEOR SHOWER: The annual Northern Taurid meteor shower caused by Comet Encke peaks on Nov. 12th. Although Taurid rates are normally low, only about five meteors per hour, those five can be doozies. The shower is a well-known producer of slow, bright fireballs visible at all hours of the night. If you’re outside after dark this weekend, be alert for Taurids.
