Comments: Imaged Saturn September 1st in good seeing targeting a complete transit of AV. Have very good data with AV nicely resolved. Detail resolved in these data. AV is well resolved at approx Lat+42.2 L3 96.3 resolved in IR data. Note, for these measurements, after very accurately aligning the WinJUPOS outline frame, a zoom factor of 2.73 was used. A series of elongated bright features are seen along the Southern edge of the NTeB, have marked one at approx Lat+30.5 L3 36.2 resolved in RGB data. A large bright spot at approx Lat-22.8 L3 37.5 resolved in IR data. The SEB is quite dark in R data, I note a strange wispy dark feature originating from approx Lat-28.6 L3 132.1 extending down and back at approx 45 degrees. This feature is in the final two R data sets from this session and I have marked those data sets with an external line along the path of the feature. A series of bright spots extend across the STeZ have marked one at approx Lat-31.3 L3 78 resolved in R data. The long lived Southern red spot at approx Lat-55.6 L3 4.2 resolved in IR data.
