Comments: Imaged Saturn July 22nd in good seeing. The 685nm IR well resolves the North polar vortex and vertices of the hexagon. IR and R data resolve the concentric structure of thin bands within the North polar collar. Within this structure both IR and R data resolve a bright spot at approx Lat+63.1 L3 299.2 both IR and R also resolve a ripple impinging into the Southern edge of the dark band that is the evolved remnant of the 2010 GWS at approx Lat+48 L3 259.9. The RGB data resolves white spots at approx Lat+36 L3 310 and Lat+30 L3 278.1
The detail descibed in my report is marked in my animations.
