As a tribute to the excellence of the images that some of you have produced
recently, here is a sequence showing the circulation of the Great Red Spot.
Its internal rotation period appears to be about 4.5 days (shorter than in
the Voyager era, consistent with the accelerated rotation reported from
Galileo images by Simon-Miller et al., 2002). 

Best wishes,
