AR's 2768, 2769, 2770 in High Res from 200mm | HA | Aug 5th 2020

[MalVeauX]

Hey all,

With the stormy season here in Florida, sometimes I get decent seeing to attempt higher resolution and fine image scales. Today's seeing was good but not as good as the other day. I tried to extract what I could from the seeing conditions around 0.4"~0.5" arc-seconds when possible to look at our three cycle 25 AR's in high resolution at 0.3"/pixel from an 8 inch solar scope. I did some small scale images in HA & CaK of the three AR's for reference of position and the difference in resolution.

(the color image of AR2770 ended up front page of SpaceWeather today)

I'm afraid these are only excellent, shame seeing wasn't quite as good as last ones. Keep up the good work.
