AR12597 in CaK - 25th September

This is the only activity to speak of on the sun at the moment, and with a decaying magnetic field no longer poses a threat for any M-class flare activity.  Taken with the Skywatcher ED80 stopped down to 60mm at ~1400mm focal length with the homebrew CaK filter and the PGR Chameleon 3 camera.
