Lovejoy Lives!

December 16, 2011

Barely.

The Solar Dynamics Observer (SDO) detected Comet Lovejoy (C/2011W3) leaving the sun, but thousands of times fainter than it went in.  the LASCO C3 and C2 images that I’ve seen for 9:30 UT show the ghost of Lovejoy’s tail.  See Below:

Ghost of Comet Not So Past

Sorry, couldn’t help it.  It’s the season I guess.  However reports of Lovejoy’s death may have been exaggerated.  Sorry Mr. Twain.

Update 8:38 a.m.

I dashed off the above as soon as I got up this morning.  It wasn’t until later looking at spaceweather.com’s animation of the LASCO C3 images that I found that the over bright star to the lower left of the sun was what’s left of Comet Lovejoy.  I took a quick look at Stellarium and saw no planets in that position, so I thought it may have been an artifact.  So it appears Lovejoy lost all its volatile components and is probably a bare nucleus like the progenitor of the Geminid meteor shower 3200 Phaethon.   I wonder if the brightness of it will change its size estimates?

    Well I need to eat my words on that one. It does look a bit smaller in the soho images..well at least dimmer. Also where is the tail!
