I see from my images of last night that there was a very prominent blue-green spot in the STrZ around III=290. This would appear to be the same one as imaged by Marc Delcroix on 2008 February 15 at exactly this longitude. Dave Tyler recorded in at III=287 on March 22. Interesting it shows up here as so green - hardly recorded in R at all,whereas Marc's early observation recorded it clearly in R (but not on April 04 and April 15,where he recorded it also prominent only in L or G). Dave's image also makes it green.

Saturn with prominent storm in the STrZ.
The animation is out of 6 green channel stacks covering a time interval
from 20:35 UT to 21:51 UT (23.04.2008). The sometimes blurred vision is due to unstable seeing conditions.
