I made an observation of Jupiter on May 31, 2004 at 00:30 U.T. under average seeing conditions (5-6/10). The North Equatorial Belt (NEB) appeared very complex and the North Polar Region (NPR) mottled. I hope that you enjoy the observation. I welcome any comments you may have on my observation.

Very little time to observing Jupiter until it goes down, though, thanks the comfort
of a camcorder I could capture this image of Ganymed's shadow.
