AR2824 in High Res WL, HA, CaK | May 20th 2021

[MalVeauX]

Heya,

I nasty storm cell swept through last night, but usually I have decent seeing after storms, so I woke up and went outside to a fairly high temperature delta from night to morning with gusts of wind, but seeing turned out to be good, so I attempted some high res imaging with a 200mm and 150mm and then finished my session with a 120mm moderate resolution imaging of the AR2824 near the limb and total session time was around 40 minutes for tri-band and two image scale captures. AR2824 has a lot more going on than the previous spot that just left our view around the limb, with a great mottling area and plage and it's throwing active small flares, would be great to see some long animations as things are moving quite a bit. My weather only lasted an hour and now its cloudy and going to rain, but storms are good around here.
