Comments: Imaged Saturn September 1st 2021 in good seeing covering 1 hr 19 min’s of Saturn rotation. Was targeting a CM transit of the 2010 GWS AV. Have resolved the long lived coupled pair of bright spots on the edge of the NPR at approx Lat+65 L3 275.4 and Lat+63.4 L3 286.8 have also resolved a mid latitude bright spot at approx Lat+ 29.3 L3 264.5. There is considerable low contrast features in the EZ and I have marked one of these bright spots at approx Lat+0.5 L1 333.6. The AV is becoming ever fainter as the year progresses and required heavy processing to glimpse it. I measure it to be at approx Lat+41.6 L3 315.5.
