Comments: Imaged Saturn August 21st in fair to good seeing. I continue in my attempt to survey all longitude sectors, particularly of the Southern Hemisphere to track the new dark feature I first imaged August 7th. My problem has been the lack of consecutive nights without cloud due to the unsettled conditions we have had through much of this apparition. These data cover 3 hrs of Saturn rotation. I note a bright spot on the Southern edge of the NTrB at approx Lat+30 L3 176.7. EZ / NEB ripples at approx Lat+15.2 L1 213.5 and Lat+15.1 L1 241.4. There are several low contrast bright and dark features within the the EZ have marked one of the dark features to be centered on approx Lat+7.3 L1 177. Southern Hemisphere features include the persistent v-large dark spot at approx Lat-44.3 L3 96.7, two dark spots on the edge of the ring shadow at approx Lat-28.8 L3114.3 and Lat-28.9 L3 99.3 another dark spot resolved only in the R data at approx Lat-31.1 L3 147.9
