http://spaceweather.comERUPTING COMET: Astronomers in Japan and Europe report that Comet
17P/Holmes is undergoing a spectacular eruption. The 17th-magnitude comet
has brightened by a factor of five hundred thousand or more during the
past 24 hours becoming a naked eye object in the evening sky. This may
signify a breakup of the comet's core or a rich vein of ice suddenly
exposed to sunlight--no one knows. Look for a yellow 2.5th-magnitude
fuzzball in the constellation Perseus after sunset. ("2.5th magnitude"
means a little dimmer than the stars of the Big Dipper.) At present the
comet looks more like a star than a comet; it does not have a discernable
tail, but it might grow one as the outburst continues. Visit
