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.

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