Observers have not yet recovered ISON after it rounded the Sun. The latest SOHO images do not show it. It is looking increasingly likely that it has not survived and that the "Comet of the Century" is no more.

Phil Plait tweeted that something was observed coming round the other side of the sun but it's not clear exactly what and in what condition.  So much for the hyberbole about it potentially being brighter than a full moon.

I hope not...that would be more than a little disappointing... :unsure2:

The experts have always said it had the potential to be brighter than the full moon IF it survived it's encounter with the Sun.

No hyperbole, just the non-specialist press ignoring some of the facts.

It's par for the course with comets. They are unpredictable by nature.

From what I watched on NASA they're pretty sure it broke up. I'm hoping something survived.

The article linked below includes a picture of the trail ISON left behind as it approached the Sun, and its faint remains emerging out the other side. No nucleus, apparently, merely debris.  http://www.nbcnews.c...-sun-2D11670914

Here's what Phil Plait posted a few minutes ago. He was on the live you tube discussion with NASA, so that's linked again here. The whole discussion is still viewable.

Comet Ison destroyed in Sun passage


www.bbc.co.uk said:

Comet Ison was severely battered in its encounter with the Sun, and largely destroyed.

Telescopes saw the giant ball of ice and dust disappear behind the star, but only a dull streamer emerge.

Astronomers continued to search for the object, but it eventually became clear that the much vaunted "Comet of the Century" had gone out with a whimper.

Opps, I put this also on another thread.

it appears a small fragment could have survived.

Comet ISON Fizzles

These images from NASA's Solar Terrestrial Relations Observatory and the ESA/NASA Solar and Heliospheric Observatory show Comet ISON growing dim as it made the journey around the sun. The comet was not visible at all in NASA's Solar Dynamics Observatory. The comet is believed to have broken up and evaporated.

While this means that Comet ISON will not be visible in the night sky in December, the wealth of observations gathered of the comet over the last year will provide great research opportunities for some time. One important question will simply be to figure out why it is no longer visible.

I was so looking forward to going out an hour before sunrise on December 1 (my birthday) and seeing an amazing sight, but alas, gone it is. If I understood what I've been reading right, most comets come from within the solar system but this one came from the oort cloud and took 50 million years to get where it was today. The data gathered will do much to help scientists understand the composition of comets and will tell a story about the region in space where this comet came from. I will miss my birthday memory but I can wait for the next one.

I had a feeling that ISON would break up upon it's encounter with the sun. When it didn't brighten up a few months ago when expected I was afraid that it would be a let down, sky watching-wise, that is.

There are always more comets and who knows when the next will come!!

R.I.P. ISON. We hardly knew you.

I personally see Ison continuing on. I reserve the right to change that opinion as more information is forthcoming.

Could fragments of ISON survived? Of course. No one said otherwise. It certainly did not survive it's encounter with the sun, however, enough to go on to become the "comet of the century" that it was hailed as.
I hope the nucleus did survive, but it's not likely.
