Solar activity 14 May 2021

At least there's less solid cloud but a very unsteady atmosphere.....
Only LW and CaK.
AR 2822 continues to impress, larger spot with penumbra and a few scattered small spots, AR2823 looks like a small "black hole" on the solar surface - very black with no penumbra.


I've tried an inverted CaK of AR 2822/2823 just for interest.
Enjoy!
(Hmmm the circular artifact which crept into the full disk CaK came back when uploaded to IIS!!!!! Re-done, re-saved and uploaded. Hopefully OK this time)
