Comet ISON observed

An update I picked up from Comet group on Yahoo,

ISON started to fade. My last measurements show that for the last 12h (from 9 to 19h UT) the comet faded by about 0.5m. However only for the last four hours it faded by more than 2m and obviously is less bright. My explanation is that due to the rapid phase angle increase up to 16h UT, the scattering effect compensated the fading. I estimated the comet to be between 2.6 and 3.1 magnitude now.

Here is last avail image from C3 at 9.32pm:



And stack showing "head" getting thinner

latest lasco c3 images show a definite fading, dont like the look of this..


the ison isoff ison comet, isoff again, real rollercoaster stuff.

Its been funny watching this on spaceweather.com, they're on about cancelling the funeral, I'd be re-ordering the coffin again if I was them lol

Well, I think that's it, it looks like just a pile of dust now.

It seems the show is over

Or maybe not! Another Comet, Seike-Lines in 1962 showed similar symptoms, in fact it disappeared after perihelion to re-appear as bright as Jupiter after 3 days! It may take that long for Ison to rebuild a Coma/Tail if anything has survived. I am not calling it dead yet!

I hope you're right

Well, it was a lot of fun anyway and hopefully a lot will be learned by the scientists
