we're happening to get hit with that bit of purple right now. it sucks but it's random; it could have fallen in any direction.

note all the bright red. that is actually a consequence of the purple dissipating, which was the cold we all suffered through. you can actually see where this chunk of purple is pinching off  at the wisconsin-michigan border, in the upper peninsula.

the red will rapidly consume the purple, and the sun is already shining again in most of the polar region.
