CaK Full Disk 4th March

The only real activity on the sun at the moment is in the northern hemisphere, with areas of bright plage.  The larger of which has a few small spots and pores but nothing of note to speak of.  This shot was take with the 40mm scope at 400mm focal length with the homebrew CaK filter and the PGR Chameleon 3 camera.
