Combined Sunspot Group & Disk Image Report

Massive sunspot activity on the morning following an Aurora Borealis evening.

Target Description	This is the first solar image I ever captured other than a solitary test image with the Seestar a couple of months earlier. All of my prior solar observing experience was visual, setting up my Askar V telescope for public use at "sun parties". Because of the previous night's Aurora activity, I expected there would be exceptional sunspot activity, and was not disappointed. It was fun to find that enormous sunspot group on the right limb.
Image Capture Description	Captured from my back deck on the morning following an Aurora Borealis. Conditions were good with no clouds and relatively stable seeing. Seeing is easy to monitor in the Seestar during solar imaging because the camera sends a continually updated video stream to your phone. Especially if look at the limb, you can readily judge how steady it is. Longitude and latitude lines added by a Freeware Windows program called Helio Viewer.

Answer the Following: -- Is granulation visible? Yes -- Is penubral grain visible? No -- Does image show Wilson effect? No Faint granulation NE of group. I suspect sunspots are too far from limb to show strong Wilson Effect.
