||Still brightening towards its
expected maximum of mag 2.5 around May 8th 2004, this fine comet is
already a naked eye object and shows a short tail when observing with 7x50
binoculars. The CCD image above reveals a real extension of the tail
of more than 3 degrees as well as an interesting disturbance. The
inset image illustrates the pale green-blue color of the comet head.
C/2001 Q4 was only 0.64 AU (astronomical unit = distance from sun to earth)
away when these pictures were taken.
The fuzzy object left of center is NGC 1313, a fine
barred spiral galaxy. The field of view is 4° wide.
