Comet Ikeya-Zhang

March 31, 2001

Uploaded 4/01/02

This 3rd magnitude object is currently in the evening sky about 10 degrees above the NW horizon at the end of twilight. The shooting window is very narrow, being a contest between sunset twilight and the comet setting into the brown extinction band (left in this image) near the horizon. Both a yellow broad fan tail seen in the background as a faint glow, and the blue Ion tail are seen here. The comets head is normally blue green, however being only 7 degrees up, the reddening near the horizon has caused it to be more yellowish.

A second image furthur up from the horizon can be seen here.
