ISON will survive!

They are claiming it's all over the the little comet that could, but I still believe it will make it around. That's my prediction.

I like to side with comets. They are so..... bipolar.....

It may do - as a rubble pile - but with no volatiles left it will be invisible - thats my prediction

Maybe it should have been named ICARUS.

It was just reported that SDO shows no sign of Comet ISON. Sadly, put a fork in it.

It's better to burn out than fade away.

However something has come through thought its looks very unheathly cometwise.

that's a dust pile with no volatility... will fade shortly.. but we are due for a good comet show its been too long

Now Lovejoy go its tail ripped off at the same point but once some distance from the sun it regrew the tail .... then totally disrupted a day later.

That looks like it is more of the rubble. The thinner "tail" going in is almost exactly on the parabolic orbital path and was said to be large dust grains and debris. Perhaps the comet did disrupt. It is remarkable that it is marking its path so well!

I guess there is no hope of seeing a Halley's type comet again in my lifetime(I was mesmerized night after night just looking at it),and I was really hoping that ISON would be that comet,I'm totally crushed.

You AND the comet, quite possibly.

It was a great comet for me, on the way down to the horizon this past month. It showed a good, long tail and a green coma. What more could I want? This was the best tail I'd seen since Schwassman-Wachmann 3 B & C in 2006. I did miss McNaught, however. Pannstarrs was pretty good too, though I felt its tail was a bit of a fan.

The NASA coverage was a shame. These people are supposed to be scientists, but they were calling this very early based on nearly no data. The mere lack of visibility in the instrument they were using was not telling of much at all.

I still think it is too early to tell. Everyone should look at those pictures. The comet, disrupted or not, is marking its orbital path in a most amazing way.

It's just the dust from the shattered nucleus - there is no drag out there so the particles will tend to follow the original orbital trajectory. In fact there will be some reconcentration as the remnants move away as the leading particles will be slowed by gravity allowing the trailing particles to catch up. The various sizes of dust grain will be "sorted" by radiation pressure & more or less gradually diverge as well as being scattered by the residual motion from the nucleus's rotation. Dispersing and moving away from the sun, the remnants will fade rapidly. If we're very lucky there may be a few chunks large enough to be visible as faint telescopic objects on the way out - probably the second week in December is the best chance to see what is left.

Comet of the century? No ... hype of the century, well one hopes that the "popular" media will learn, but without much expectation.

The "Comet of the Century" label should be based only on performance, never on expectations. If it doesn't put on a fine show, clearly visible and easily found by anyone, sporting a long, bright tail, it should not qualify.

Clear skies, Alan

Sounds like you missed Ikeya-Zhang and C/2006 P1 McNaught both recent and bright with tails
