Comments: Saturn June 4th 2020, 685nm IR data resolves the quite intricate structure within the North polar collar along with the 2010 GWS AV at approx Lat+43.1 L3 55.1. All wavelengths resolve the ripples on the edge of the EZ although only the westernmost remains prominent. The preceding two ripples are becoming more difficult to detect, however that maybe influenced more by the quality of the data.
The R and RGB data well resolve a large bright spot just within the polar collar, this feature has been prominent for some time. I measure this spot to be at approx Lat+63.9 L3 7.1
The thin bright streak in the NEB following the westernmost ripple in the EZ is well seen in the IR data
