May 21, 2018: WL and Ca-K disks with new AR

[michael.h.f.wilkinson]

Fewer proms in the Ca-K part inverted view, but a new sunspot has turned the corner. It is quite small, but there is some bright plage around it. Seeing was pretty choppy, especially in Ca-K, but I still got reasonable.

I also got some H-alpha data which I will post later, if all goes well

That is a tiddler! I would never have spotted it without the CaK images to point the way.

Nice captures. I managed a quick visual at lunchtime but think that may be it for the day today.

What a super set of images Michael, thanks for sharing.

Nice images. Well done! I saw the new AR earlier on, and also again just now. When the seeing was steady with my Omni 120mm frac with my Lunt wedge fitted with a 10mm Delos EP I could just make out too a couple of smaller pin pricks of spots immediately behind the one you can see in your image. Be interesting to note if I can see them better in an hour or so perhaps.

Lovely looking disc's.
