DENVER FIREBALL: A spectacular fireball streaked over Denver, Colorado, this morning. Observers described it as "brilliant, slow, twinkling, sparkly and full of rainbow colors." Contrary to some reports, it was not a Quadrantid meteor. It was the decaying body of a Russian rocket that launched the French COROT space telescope on Dec. 27th.

HOT COMET: Comet McNaught (C/2006 P1) is plunging toward the Sun. It won't hit, but at closest approach on Jan. 13th it will be much closer to the Sun than the planet Mercury. The comet will experience fierce heating and it could brighten considerably, emerging from the encounter brighter than a 1st magnitude star.
For the next few mornings, northerners can see Comet McNaught before it disappears into the Sun's glare. It's an easy target for binoculars hanging low in the eastern sky at sunrise. After Jan. 11th, only SOHO (the Solar and Heliospheric Observatory) will be able to track the comet as it angles toward the bright Sun. SOHO images are posted in near-real time on the Internet, so you can watch the comet-sun encounter and see what happens.
