Comet Elenin is passing across the STEREO H1B field of view fading as it goes. The comet is actually brighter on the 16th than the 17th, despite what it looks like in the image, as the corona was much brighter on the 16th, and washed out the comet when I increased the brightness. I've made a little AVI animation of the August 17 images (1 Mb).



Some recent Earth-bound images of Elenin are here and here.
