In good seeing.
Quite intricate concentric rings of structure are seen within the North polar collar in both 685nm IR an R channel animations,particularly so in IR. The IR also resolves diffuse spots in contact with each flat of the hexagon. The 2010 GWS AV is well seen in IR at approx Lat+43.1 L3 48.4.
The RGB resolves a bright spot at approx Lat+36.1 L3 4.1 while data at all wavelengths resolves a bright spot in the EZ at approx Lat-5.5 L1 161.2 interestingly the Ch4 data also resolves a bright band within the EZ. There is also a large diffuse bright spot within the North polar collar best seen in the RGB data but it is very near the P limb in the first R & RGB of the session so is seen to rotate over the limb in the RGB animation.
