Another Comet?

SOHO and STEREO are reporting another Kruetz comet moving toward the Sun. It is expected to make its closest approach to the Sun tomorrow, March 14. If it survives perihelion and is bright enough, we would see this comet appearing in the upper right side of the Sun and moving down over the disk. Current estimates are that this comet is smaller than Lovejoy. At this time we do not know the time of perihelion passage.

We have a daily eclipse of the Sun by the Earth (at 0630-0730 UTC tomorrow), and a momentum management burn tomorrow at from 1845-1915 UTC. During both periods the images of the Sun may be absent.
