Here is an observation from July 16th 2004. The 09:05 UT image was processed
to show the variation in brightness across the globe of Uranus. The
brightest area shown in red is believed to be the south polar region. The
transparency was good 6/10 and the seeing was very good, 8/10 with moderate dew.
