Wow, according to the latest photo published by SOHO there may still be a solid core intact.
ISON Update for 22:00 UTC Nov. 28.
[UPDATE 2 (Nov. 29 at 02:30 UTC): This beastie continues to surprise. This SOHO image, from 00:18 UTC on Nov. 29, sure looks like something survived intact. At this point all I can say is the same thing I've been saying all along: predicting comets is like predicting cats. Good luck with that. For those keeping score at home, it got bright, then it faded, then it got all smeared out, then it came around the Sun smeared out, and then it seemed to get its act together again. At this point, I refuse to make any further conclusions about this comet; it seems eager to confuse. I've been hearing from comet specialists who are just as baffled... which is fantastic! If we knew what was going on, there'd be nothing more to learn.]
