in mostly good seeing, the North polar vortex and vertices of the hexagon are well resolved. The long lived dark spot / bright spot combination just inside the polar collar (NPR) are very well resolved in the 685nm IR data and are glimpsed in R and RGB data.
All data well resolved the large amplitude ripple on the edge of the EZ impinging into the NEB.
I measure the NPR dark spot to be at approx Lat+63.7 L3 246.6 bright spot at approx Lat+63.6 L3 255.8 with the EZ ripple at approx Lat+14.4 L1 236.1.
