CaK Full Disk With A Spot - 23rd March

The full disk is still quiet, even in CaK light, but on the eastern limb a new sunspot rounded the limb; it is small and rather inactive looking, but nice to have a feature on our star.  Fingers crossed I will be able to get a closer look over the coming weekend.  Taken with the 40mm scope at 400mm focal, with the homebrew CaK filter and the PGR Chameleon 3 camera.
