Comments: Imaged Saturn November 13th with four IR data sets covering 68 min’s of Saturn rotation in poor seeing. Started out with 685nm IR and tried 742nm and 807nm but the 742nm IR handled the poor seeing a little better. I had no expectation of resolving small scale discrete detail with this data but there is a dark spot resolved at approx Lat+64.9 L3 66.5, this must be quite a prominent feature to be resolved in this level of data. This dark spot is well seen in the IR animation. Regarding the JWST observations I note that the long lived AV which is currently at approx Lat+42 would have been at an L3 of approx 176 degrees for November 13th.
