Latest estimate on Comet Lovejoy's brightness is that it has reached magnitude +1, and we're looking for the first hints of blooming artifacts in SOHO LASCO C3 that will indicate that the comet has brightened into the negative magnitudes. Later today I expect to get an update from Karl Battams at NRL with the STEREO-B images from 13 December. When I do, I will append them to the existing movie. I'll also put together a movie from LASCO C3, and perhaps Jim Wooddell will be kind enough to host it as well. As for the closest approach distance of Lovejoy to the surface of the sun, there are some estimates out there that the distance will be effectively zero -- a true surface-grazer. As such, the chances for survival past perihelion are zero, unfortunately. Best wishes, Rob -----Original Message----- From: Sterling K.

It's much better than the others I've found on various websites. It gives one a sense of what poor old Lovejoy is heading into! Yes, it's unlikely there will be anything left after it passes only 87,000 miles above the solar surface, but it would a fine Christmas present if there was a brief negative magnitude comet show afterwards.
