Comments: Sat North Polar storm bright active region centered at approx Lat+65.8 extending in longitude from L3 204 back to L3 250 preceded by two bright spots at approx Lat+65.4 L3 184 and Lat+65 L3 165.7 Preceding all of that is another bright active region which hooks back up into the dark polar collar. This region extends from Lat+66.1 L3 128.4 back to Lat+71 L3 166 The very complex structure of the North Polar Storm extends in longitude by at least 120 degrees.
Also there is a small bright spot/oval on the southern edge of the thin dark band left from the 2010 GWS I measure it to be at approx Lat+45.8 L3 222.1
