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. John

It is based on ground-based observations and starts from Dec 10 and projects forward to Jan 24, 2011. (It correlates to images already acquired between Dec 10 and Dec. 27th.) Assuming a "System II" cloud rotation rate of 10 h 39 min, the storm is tracking westwards 3 min every Saturn rotation. Effectively the storm is rotating around Saturn every 10 h 42 min as viewed from Earth. The best views will be about 30 minutes or so before the storm is at dead center on Saturn's disk. Enjoy!
