Comet ISON reached perihelion at 18:25 UT (10:25 PT). It's was an event that's was watched around the world, accompanied by tons of commentary and streams of photos. We updated this blog entry periodically with links to all the resources that we hear of for following the comet's progress.

Update: Comet ISON is at least mostly dead. Most think all that remains is a rapidly fading and dispersing cloud of dust. For insights on what happened, check below and the links therein, and read Bruce's Comet ISON wrap up blog (A Tail of Cat-Possums and the Undead), and check out Emily's animations page that includes animations of images from many different solar observation spacecraft, as well as seeing the animations below, and check our Comets page that will list all recent Planetary Society posts on comets, ISON or otherwise.

Had enough animations yet? Here's one from the STEREO Behind spacecraft, a unique perspective on the comet rounding the Sun. I (Emily) am not sure why it's so much brighter in this view than in the SOHO ones -- I suspect that the viewing geometry makes dust much more visible than from other points of view.
