Comments: Imaged Saturn August 25th in fair to good seeing. The 685nm IR data very well resolves the North polar vortex and vertices of the hexagon and also resolves the thin concentric banding structure within the North polar collar. The R channel and RGB data nicely resolves the fast moving bright and dark spots just inside the North polar collar. I measure the bright spot to be at approx Lat+62.9 L3 104 and the dark spot at approx Lat+63.7 L3 93.4. Also have a quite nice Ch4 data set
