There is still
plenty of color in the now rapidly dimming comet, in a month
it will be 10th magnitude. A broad fan tail points to about 9:00
in this image, and a slightly diffuse stellar nucleus is still
visible. In 15 minutes there was some motion in the comet, as
evidenced by the slight trailing of the stars in the background.
The comet was carefully aligned in each subframe to stop all
of the comets motion in this image.
Two 16th magnitude galaxies
are on the left edge, and this rather star poor field is typical
of Ursa Major. The comet was of course not naked eye, but was
clearly seen in the 11x80s as a faint tailless smudge.
