Comments: Imaged Saturn July 25th in good seeing. The North polar vortex and vertices of the hexagon are well resolved. The 685nm IR resolves a compact dark spot at approx Lat+60.3 L3 125.5 this dark spot is led by a large diffuse bright spot resolved in R and RGB data but best seen in R, this bright spot is at approx Lat+63.1 L3 114.8. I also note in IR at least two ripples in the Southern edge of the dark band evolved remnant of the 2010 GWS at approx Lat+48.6 L3 215.9 and Lat+47.8 L3 186.5.
