That's a shame, I was even hoping to have an event at my house with friends to observe the comet in the morning. We'll see though, comets have made it past the sun and come out from perihelion much brighter than anticipated.

Image of ISON from yesterday morning next to a few galaxies, including NGC 3428 and NGC 3429. I used a Meade 20" RCX400 Max Mount for luminance and Televue NP101is for color data along with an STL-1001e on the 20" and ST-4000XCM on the Televue.

This really is one odd comet. I wonder if it's going to pull a C/2011 W3 "Lovejoy" and brighten exponentially once it moves away from the sun.

Now don't kill him Sun, or I'll always sleep from sunrise to sunset

Weather seems to hate me right now, I went back to bed this morning after seeing clouds covering the horizon.

Got up early this morning and was able to snap some pictures of it; pretty faint still though

Happy Perihelion day for Comet ISON!

Getting closer, let's hope she doesn't burn up!
