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.

This seems to be a re-occurring phenomenon on Saturn - remember the large equatorial outbreak of 1990?
http://hubblesite.org/newscenter/archive/r...s/1991/1991/04/ Of course, English actor and comedian Will Hay is famous for (probably) being the first astronomer to observe one of these white spots, back in 1933: http://en.wikipedia.org/wiki/Will_Hay#Private_life -------------------- |
