Comments: Imaged Saturn August 17th in goodish seeing. I note the long lived pair of bright spots on the edge of the NPR at approx Lat+64.4 L3 96.3 and Lat+63.3 L3 107.4 along with a mid latitude bright spot at approx Lat+29.2 L3 97.5. The EZ has considerable low contrast activity, that said there is a very bright Southern plume at approx Lat-4.6 L1 315 with another v-bright spot above it at approx Lat+1.1, these plumes seem part of a larger feature that extends vertically almost to the EZ / SEB border and is particularly conspicuous in the 685nm IR animation. This feature is also just detectable in the R and to an even lesser extent the RGB data sets.
