AR12305 CaK Closeup 30th March

Slightly hazy conditions for this image taken right above the rooftops first thing this morning, but shows this monster active region before it passes over the limb, and, also, on the limb a lovely bright surge prom.  Taken with the 40mm scope at 900mm focal length with the homebrew CaK filter and the DMK31 camera.
