The solar system is a happening place this week! I just learned of a major storm in Saturn's northern hemisphere, being monitored by the usual band of talented amateurs. See this site for a list of recent images. Chris Go's site has a particularly nice image.

CB2 frames are 3.2 seconds exposures. MT frames are longer IIRC.

CB2 frames are 3.2 seconds exposures. MT frames are longer IIRC. Mea culpa! Still, for 4 second exposures you'd need 10 km/sec (22,000 mph) winds to blur by a couple of pixels, so I think we still have to conclude that the storm clouds are intrinsically "blurry"- overlying high cirrus, maybe?
