NASA tweeting that fate of ISON not yet established.

 

What ? Did it defy Physics pop down to the surface of the sun for a bit, before carrying on it's wonky trajectory.

 

Interesting C3 imagery coming out now.

Skirted a teeny bit above it... Whatever's survived, it's not going to create a spectacular show, sadly. To be fair, the astronomers prefaced every statement with "If if survives". The media were, as ever, the ones hyping it up.

ISON has appeared from behind the sun and it seems to be brightening again. Interesting.

Apparently a sharp pointy edge means the nucleus has exploded, whereas what I'm seeing is a rounder edge, very similar to Hale-Bopp. (Although obviously not on the same scale)

Still looking very bright, not sure what trajectory this should be on , if this is a remnant or if the nucleus has popped and this is a fragment??

Is that it at about 11 o'clock which seems to be a brightish spot with a bit of a tail pointing back towards the sun? but surely on its outward journey the tail would be pointing away from the sun.

Looks like a comet to me.

The tail should be between the sun and comet if its there so it looks fine. Towards the sun and you'd have sun, comet, tail.

TInfoil hat and all that - wonder what the predicted trajectory is ? if part of it sheared off and altered this, it looked like this happened in the earlier C2 Image, ( red one) which shows dust cloud well ahead of the position of what is now potentially the reduced nucleus.

 

Anyone better informed to clarify what was expected?

Something remains of ISON, but what? It's massively fainter than it was at approach, should be very bright now. The nucleus must have disintegrated to some significant extent, are we seeing just a trail of dust, gas and gravel or are there a few larger fragments still left. Time will soon reveal I suppose.

It's possible that the brightness could be explained by the chemical reactions while round the sun or it may look great again soon.

do you not think they maybe just got caught out as they thought it disappeared going past the sun but what you will find is it was probably just the tail getting totally obliterated by the solar wind which means we couldn't actually see the comet till it got far enough away from the sun for its tail to stabilise again and reform.

in the video more so the first one when you see the blow off as it gets close to the sun that could simply be the tail getting being taken away as it hits a certain distance from the sun after all its mostly just steam then after you can still see a streak going round the sun that will be the gases being left but no steam it simply boils off too quick.

 

https://www.youtube.com/watch?v=6j6nkLnHyG0

 

the images you are seeing now is from it getting to that same distance away from the sun that stopped the tail and it is now reforming and brightening and may become brighter due to the energy received from its interaction with the sun and will stay brighter till that energy is released.

 

obviously it will have lost some mass from its encounter and will be smaller but from the images it still very much looks like a living comet.

 

EDIT: sorry not the first bit its at about 28 seconds.

is it not worrying that something made it round the sun and is seen on images above brightening up but everything has gone quiet over twitter and things

also same questions as LORENZO asked above concerning trajectory etc.

An astronomer on the BBC just said that whatever made it around the sun appears to be brightening and didn't mention anything about it being destroyed.

Now the BBC are going with news bulletins saying 'Comet Ison still intact?'

 

Certainly a lot of confusion surrounding this comet.

Hopefully some spectacular sights over the next few weeks.

 

We all thought it was was done. After some new analysis comet experts are feeling confident that there is at least a small nucleus intact. Their initial analysis indicates that it is still behaving like a comet. An extremely exciting turn of events.

Media say not :(

 

Comet Ison Comes To A Fiery End Near Sun
 
Comet Ison has failed to make it around the Sun - meaning stargazers will miss out on a spectacular show next month.

Comet Ison destroyed in Sun passage

 

Comet Ison has been 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 re-emerge.
 
 
Here's a close up, Hi-Res picture of what's left:
