Imaged Saturn October 31st in mostly good seeing, my best Saturn data for October. The 685nm IR data very well defines the North Polar vortex and vertices of the hexagon. The IR data resolves a bright indent or ripple into one of the flats of the hexagon at approx Lat+78.8 L3 328.4. The IR data also resolves the fast moving dark spot / bright spot combination at approx Lat+64 degrees very near the F limb; I also believe a long lived dark spot at approx Lat+61 degrees is seen in IR data adjacent to the +64 degree dark spot. I measure the dark spot / bright spot combination from the R data to be at, dark spot approx Lat+63.7 L3 357.1 bright spot Lat+64 L3 12.3. I measure the adjacent dark spot from the IR data to be at approx Lat+61.7 L3 5.8. The RGB data resolves a bright spot immediately beneath the thin dark band of the NNTeB at approx Lat+47.1 L3 269.9 and a large diffuse bright spot at approx Lat+30 L3 317.1, all of the features described above are marked in their various animations.
