As far as I know the comet will be at perihelion tomorrow, but is it impossible to still view the comet or will I have to wait until the weekend to find out if it survived?

You can keep track of it here

Great find stu

Can't claim it as my find, it was posted here on SGL and on FB, but it's a great clip and will be amazing to watch it as it progresses. There is a huge CME spreading out from the sun which may disrupt the tail, fascinating to watch

Nice video clip. Does anyone know often it is up dated?

There is a date and time stamp at the bottom, I'm pretty sure it is over a number of hours. Not sure what the scale of the image is though. I've read that it is travelling at 270,000 mph currently and will round the sun at much higher speeds, between 500,000 and 1 million I've seen quoted, not sure which, if any are accurate.

Unfortunately, there are some indications that the nucleus may have fragmented.

Fingers crossed, it's too early to be sure, but don't be surprised if it doesn't survive perihelion.

Yes i had read similar somewhere else. The signs are not looking good. But i did read that even if the nucleus fragments it will still present a dramatic sight in binoculars and scopes. Trouble is i can't find the site i read this all on.

Very interesting, thanks for posting.

I can see we're looking at ISON but will someone explainfrom where is the image captured, in other words, what vantage point are we viewing the image from? Earth, a satellite, HST?

The video was taken from SOHO, a solar observation spacecraft. ISON is so close to the Sun that observing it from Earth is very difficult now.

Many thanks Knight,

I am reading up now on your Wiki link.

I'm afraid that excitement gets the better of me and a question to the forum gets ahead of my ability to do my own follow-up research!

Thank you again,

Tim
