It appears Comet ISON, like Icarus, flew too close to the Sun, and has suffered a similar fate.
Final pic from Lasco C2 leaves more room for Ison still surviving than the second to last pic which was very tiny point-like.

What’s your source? The ESA pix have the comet blocked and only the tail is exposed, it’ll take a while to get photos to show more recent tail material, let alone the nucleus.

Perhaps Bill – but my Mk 1 eyeball suggests it’s trajectory is darned close? I’d be surprised if it comes out the other side!
BBC are saying that the comet has not survived it’s scrape with the sun.

Circumstantial evidence.
1. Nothing appeared in the SDO images, which don’t have an occulting disk and therefore could have followed the comet through perihelion.
2. In the STEREO Ahead images, the comet appears to go “poof” (technical term) just before perihelion. See: http://www.spaceweatherlive.com/en/comet-ison
I could be wrong, but I don’t think so.

That’s a pretty convincing poof. I suppose it could be that just the surface blew off and the cold core needs more time and heat to regenerate a tail, but I fear it’s time for the pity party. Dang comets are harder to predict than the climate.
This is the message on the website Ric, I think we have seen the last of Ison.
“There are reports that Comet ISON has not made it through its close encounter with the sun, however this data will remain here until this is confirmed by the appropriate organisations.”
spaceweather.com is definitely saying ISON has gone, but from my view of LASCO C2 20:36UT (74 minutes ago) a small remnant has survived. Presumably this is going to be fairly faint once it moves away from the Sun’s glare though. I may need to get my 6″ telescope out to find it. Another “I could have been a player, man” comet…

And still there at 21:24UT.

From http://www.isoncampaign.org/karl/schroedingers-comet , a theory agreeing with my suggestion it was still there:
But currently I can’t get any recent LASCO C2/C3 images.
Amazing that there were no new comments since mine at 2:12pm, but I suppose that’s Thanksgiving for you.
Rich.
I’m now finding that http://soho.esac.esa.int/data/realtime/c3/512/latest.html or http://soho.esac.esa.int/data/realtime/c3/1024/latest.html is a better place than http://sohowww.nascom.nasa.gov/data/realtime/c3/512/ from which to download images. The 09:11 one today shows a brightening comet!

The NASA is still (14.09 French time) displaying the “Comet ISON Fizzles as it Rounds the Sun” headline and analysis:

Probably desperately looking for the right words for the incomprehensible (because comprehended) update…

“BBC are saying that the comet has not survived it’s scrape with the sun.”
BBC has a complicated relationship with objective truth.
Well it looks like it did survive, whatever part is seen getting further away from the sun:

DirkH,
Charitable way of putting it.
Others who have a ‘complicated relationship with objective truth’:
Richard Nixon
LBJ
Bill Clinton
Obama
Others come to mind.
