Hi all,

 

Stormed and rained so far this week, but this morning was clear, lower temps and pretty ok seeing conditions between gusts. AR2822 is still looking good with a nice penumbra around the spot in the photosphere and lots of interesting activity in the chromosphere and popping off little flares.
