Image caption: Image of the solar corona, taken by the SECCHI inner Heliospheric Imager (HI-1) on the STEREO Behind observatory on March 12, 2013 at 06:49:44 UT. Image credit: STEREO latest images and daily browse images. This remarkable image is just one of many showing comet Pan-STARRS from the vantage point of one of the STEREO spacecraft. See Where is STEREO? Dark and bright vertical lines are detector artifacts.

Update: A recent NASA video has the comet moving up along the dark line, which is itself moving across the image. The dark line may be a slit for spectroscopy of moving objects.
