So sad.

Just when your hoping for a bit of decent sky-gazing, the universe says no

Even if it was going to be perdy the uk weather would have said no.

I'll still be looking - Who knows, maybe the pig will learn to sing?

The weather always says no in the uk.

I saw it a couple mornings late last week. I set my alarm an hour earlier than I usually get up for work. it was pretty easy to spot unaided. then again I live in the middle of nowhere.

seems it may have busted up a little on it's swing around the sun. don't know for sure but I just heard it looks like it's not whole anymore.

I am feeling a bit sad. I wanted a picture of this. Taken from my cheapy Samsung on a spider tripod.

Is it not happening now?

guess that depends on what and how much of it is left.

I don't think ISON will break up and here is why I don't think so.

First, ISON is big. I have read estimates of between 1 km and 500 meters, which isn't exactly small..

Second, it gets a bit of shielding from radiative heating by its coma. The coma is being pulled away by the solar wind, but it is still enough to slow the Sun's heating.

Third, while the Sun's corona is very hot (hotter than its surface) it is also very thin. It's really a vacuum, just a slightly thicker vacuum than the vacuum that is out by Earth's orbit.

Fourth, it's not going to be near the Sun for very long. It's currently moving at 115 km/s and will be moving even faster on the 28th. It is currently 23 million km from the Sun. It'll go past the Sun by 750,000 km on the 28th. By the 30th it'll be 25 million km away from the Sun (heading roughly towards us and north out of the ecliptic). In 4 days it will manage to cover almost 50 million km, which is roughly 1/3 of the distance from the Earth to the Sun.

What might happen is either ISON comes through in one piece (admittedly smaller than it was) or tidal forces from the Sun's gravity will cause it to break apart. If it does break up, it should have a larger tail than if it stayed in one piece. Comet Lovejoy (2011) for a quick comparison was only 500 meters in diameter. At perihelion it was 5 times closer to the Sun and was moving at 500+ km/s. It survived intact and gave everyone in the southern hemisphere a great show.

/crawls back to bed.. I hate being sick and not able to sleep. Cry I hope I answered some questions.

Not to say you're wrong, but there is this article here:
http://www.usatoday.com/story/news/nation/2013/11/28/comet-ison-nasa/3776419/

Relevant quote from article:
Like Icarus, comet ISON appears to have flown too close to the sun and broken up in its corona.

Scientists had hoped that the comet from the farthest reaches of the solar system would be able to slingshot around the sun Thursday and emerge streaming a tail visible to the naked eye next month.

But after NASA telescopes tracked the comet plunging into the sun's corona, no evidence of it emerged on the other side. Scientists said they would continue to analyze imagery from the telescopes for signs of the comet or debris from it breaking up.

"At this point, I do suspect that the comet has broken up and died," says Karl Battams, a comet scientist for the Naval Research Laboratory, who joined a NASA and Google+ chat from Kitt Peak Observatory in Arizona.

And this article:
http://abcnews.go.com/Technology/comet-ison-disintegrate-passes-sun-today/story?id=21041610

Relevant quote:
Karl Battams , a comet scientist for the Naval Research Laboratory, tweeted out this afternoon: "We see zero sign of a nucleus, which is not good."

During the end of a live NASA host Google+ Hangout to answer questions about ISON, solar physicist Alex Young said: "It's unfortunate that it doesn't appear that we'll see it."

"For whatever reason, we don't know right now, we may never know the reason why it just was not stable enough or perhaps the gravity from the sun (was the cause)," Young said. "The gravity is so strong that each ends experience is different than the other end and that just tears and rips and pulls at the comet and in this case, perhaps it just experienced so much stress that it broke apart and once it broke into its little pieces then they all melted much quicker and perhaps we lost it."

Even with the disintegration it still offered a glimpse into how comets interact with the sun's magnetic fields.

It's not looking good for ISON at all.

ISON decided it couldn't after all
