Comments: Imaged Saturn July 26th in fair to good seeing and have quite interesting data with considerable small scale detail resolved. Of particular interest are a pair of what I think are vortices on the edge of the NPR; not at all dissimilar to 2020 albeit somewhat fainter. So, a dark spot preceding a bright spot, the bright spot seems to impinge into the edge of the NPR. This is best seen in my 685nm IR data s2022-07-26_14-59_ir_tba, this is also well seen in the polar map of this data set. The bright spot is also well resolved in R and RGB data sets. I measure the NPR bright spot to be at approx Lat+66.1 L3 304.3 the dark spot at Lat+65.1 L3 294.5. I note bright ripples impinging up into the Southern edge of the NNTeB at approx Lat+47.2 L3 336.5 and Lat+46.7 L3 58.8. A bright mid latitude spot approx Lat+30 L3 349.4 a dark feature at Lat+31.9 L3 6.3. EZ / NEB ripples at approx Lat+15 L1 297.6 and Lat+15 L1 323.9. There are several well defined low contrast dark and bright features within the EZ I have marked one of the dark features at approx Lat+6.3 L1 224.3. Southern hemisphere large dark spot at approx Lat-32 L3 353.3 and bright spot at at Lat-29.6 L3 334.2. R and RGB data also resolve a bright spot at Lat+63.1 L3 308.
