-------------------------------------------------------------------------------------
My first really good night for this apparition,with very good seeing and excellent transparency.
Note the rapid evolution of clouds inside the north polar hood in less than two hours of time.
The main question for me now is do we see the polar cap itself or not. I'm of the opinion that the cap is formed during autumn/winter time (MGS and HST images taken at that season are not ambiguous to my eyes). On the images (but also on some from others observers),the white area in IR looks now too regular and sharp to be only clouds. That precise area takes on a dull white-pinkish hue a bit different from the usual white-bluish tint of the hood.
Best wishes
