Sun in Ha, CaK & 'WL' including flare 22nd April 2021

Post by Carbon60 »

Yet another beautiful day as high pressure continues to dominate our weather here in the UK and an opportunity to capture some photons in Ha, Ca II K and green continuum.

The 'star' of the show is AR12816 which continues to pump out minor flares, one of which I was lucky enough to capture this morning.

First up, the FDs in three lights.
