Thanks, hope it starts to leave the "smudge" stage behind soon.

Joe, ISON is still about 4.6 AM from the Sun. Perihelion isn't until late November, when it will get only about a million miles from the Sun. It's a Sun-grazer in every sense of the word! For contrast, Comet PANNSTARS, which we'll be seeing (we hope) in another couple of weeks has a perihelion distance of roughly the Sun-Mercury distance of ~28 million miles. As many images as Patrick is taking, he'll be able to stitch them together into a "movie" showing ISON's passage against the background stars and show the comet's gradual brightening and growth in the months ahead. Because it's a Sun-grazer, and it's an Oort Cloud object making its first approach to the Sun, it promises to be super-bright. Then again, always remember Kahoutek. The challenge for ISON viewing this late November and early December is that because ISON is a Sun-grazer, to see the head of the comet you'll practically need to be looking at the Sun. For most folks, I think our best bet is to look for the tail rising brightly in the east prior to sunrise, or if we're lucky, get a view of a _daytime_ comet.

Shoot - fingers typing too fast for my slow brain to track. I meant to say that ISON is currently about 4.6 AU from the Sun.

Fingers crossed for late this year. But I'll believe it when I see it. BTW, the new issue of S&T (available for free download to those with paid subscriptions to the paper version) contains an article about Comet Kohoutek entitled “The Comet of the Century proved to be anything but". Thing is as most comets go Kohoutek was actually pretty good. I was going to flight school in Tulsa at the time and could see it with binoculars from my place in the city. It's just that it got so overhyped that most public felt burned so, unfortunately, a couple of years later when the truly magnificent Comet West burst onto the scene many did not even bother to look. patrick
