Comments: North Polar Storm bright active region at approx Lat+65.4 consists of a line of at least 6 discrete bright spots extending from L3 42.5 back to L3 117.1 followed closely by another bright spot at approx Lat+69.8 L3 144.3 thus the main region of the storm extends in longitude over at least 100 degrees. Of further interest is an isolated bright spot leading the main active region but further North at approx Lat+75.8 L3 33 this is best seen in the RGB data and shows up well in the RGB animation. There are also multiple EZ features.
