Comet C/2012 S1 ISON Brightens, comparison with Lovejoy (28 November 2013)
|Comet C/2012 S1 ISON in the SOHO Lasco C3 imager at 00:30 UT 28 November 2013||Comet C/2011 w3 Lovejoy in the SOHO Lasco C3 imager at 09:30 UT 15 December 2011||Overlay of the two images|
Comet ISON continues to brighten, its head is now brighter than comet Lovejoy at a similar distance from the Sun in the STEREO imager (ISON was at 0.084 AU from the Sun in this image, Lovejoy was closer at 0.079 AU). ISON's tail is a bit wimpier though.
What does this all mean for ISON's chances of survival? Who knows, we just have to keep watching.
What would be better would be overlays of the high resolution COR2 images, but we have to wait for them
Compared to McNaught: http://www.youtube.com/watch?v=EAJgVK-WnHY or other bright comets ISON doesn't look so impressive any more: http://www.youtube.com/watch?v=2Bi6cY53CGw
I have been tracking this comet
since it was discovered this year
and I can't believe it if it survives the perihlion today.
