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.

A most amazing eruption is occuring on comet 17P/Holmes which was at 17 mag. at best but on October 24
suddenly began to brighten like crazy: Now (afternoon UTC) it has already reached 3rd magnitude and is
easily visible to the naked eye, as reports from Japan indicate: "Perseus does not look 'Perseus'
familiar to us due to the bright stellar object now."</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.astro.uni-bonn.de/%7Edfischer/mirror/306.html">The comet looks like a bright, yellow
star, and only magnification reveals a fuzzy coma around the dusty core. Holmes was discovered in 1892
thanks to a similar outburst, and hope is that the further development will be similar now: the coma
should expand over time but stay bright for a week or more.</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/142386DD-AA29-4034-A1BA-285B574DC382/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
