CaK Full Disk - 24th May

Despite heading on a journey towards solar minima the suns current geoffective face is quite busy, with bands of activity either side of the solar equator.  These are slowly rotating away, and not much seems to be rotating to replace it - we will see over the coming days I guess!  Taken with the 40mm scope at ~500mm focal length with the homebrew CaK filter and the PGR Chameleon 3 camera.
