Comet C/2012 S1 ISON Brightens, comparison with Lovejoy (28 November 2013)

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.
