What a day! I set up as it was predicted to be sunny, cloudless all day. I waited until 13:18 UTC for enough breaks in the sky to grab a quick full disk, but this was still with some cirrus clouds. Then by 14:40 it had "cleared" enough to grab one more animation of that great prom on the NW Limb. It wasn't without its challenges though. I think Cirrus Clouds are the norm now, and they simply form, pass over the disk, clear away, rinse and repeat! I had so many of the 160 captures that came out darker that I wondered if I would be able to do anything with the animation. It took a number of passes with Pixinsights Batch Linear Fit just to get the surface histograms close enough so I could even get Photoshop to finally align the frames. Even after that there was still a problem with the histogram changing constantly. I finally ran them all through the Batch Linear Fit script one last time and I ended up keeping all of the frames. I was shocked!
The full disk shows additional activity that I might have pursued but it was past noon and the seeing was getting worse as well as the cirrus clouds so I decided at the beginning to just take a crop of that region on the NE limb. Looks like it could be a nice active region about to make itself known.
