The Sun - 18th September 2021

[David Smith]

Exactly 2 months since my last solar session! There probably have been opportunities for me to get a session in but today is the first day I recall where I felt confident that, if I got the scope out I would actually get a half decent session in. So today I set up the scope for white light, plugged in an eyepiece and hey presto blank disk, typical! Fortunately Calcium K and H Alpha proved somewhat more entertaining with a massive prom complex on show in both lights. Actually managed to capture a full disk in 3 lights, although the H alpha was touch-and-go for a while with clouds intervening in the capture and then the pano would not stitch initially. A quick re-stack with a flat, pushed the sharpening in ImPPG a bit and it finally submitted.

So 3 disks, first up that uber-exciting white light disk. Despite the lack of activity I was still able to stitch a 6 pane mosaic. I know other people look at a blank disk and move on but I find looking for the smallest details in a spotless disk kind of satisfying.

Then on to Ca-K

 

And finally H Alpha, plenty going on here with proms and filaments to enjoy.

looks like you caught that active region before it blew its top

Sweet shots, good to see you back in action, David!

Hopefully the white light is the calm before the storm!
