Comments: Imaged Saturn July 14th in good seeing covering 3 hr 5 min of Saturn rotation with continuous data capture other than when changing filters and rotating the dome. Have resolved considerable small scale detail which I list here but I particularly note the very thin white cloud strip in the NEB very near the edge of the EZ. This strip has been visible for several years, since the ripples that impinge up into the NEB were first seen in the EZ. The western most of the series of ripples has always had the highest amplitude and these data resolve its proximity to the thin cloud strip quite well. In my R data s2022-07-14_17-36-54_r_tba and 685nm IR data s2022-07-14_17-28_ir_tba I have included 200% insets in both of these particular data sets. The R data shows possible connection between the peak of the ripple and the cloud strip as does the IR data. Measured detail in these data. A dark spot at approx Lat+64.4 L3 77.8, bright spots Lat+56.6 L3 25.1 and Lat+62 L3 92 Mid latitude bright spots approx Lat+29.3 L3 68 and Lat+30 L3 353.1. Three ripples impinging up into the NEB at approx Lat+14.1 L1 196.2, Lat+13.8 L1 170 and Lat+13.8 L1 142.5. EZ bright spot Lat+8.8 L1 205.6, EZ compact bright spot Lat-3.7 L1 208.8 EZ bright elongated feature Lat-4.2 L1 163.5. Southern hemisphere bright spot Lat-30 L3 15.5. Note; there are multiple low contrast bright and dark features in the Southern hemisphere and I have marked one to provide some perspective to the other features, this was also the case in the EZ.
