AR12648 in CaK - 4th April

Conditions were far from ideal with boiling seeing and poor transparency with all the haze, but using 2x2 binning with the 80mm scope at around 2000mm focal length meant I was able to keep the exposure time short enough to freeze the seeing.  I was pushing it with this image, but nice to get a closeup of this active region, even if it is not particularly large compared to ones of the last week.  The home brew CaK filter and PGR Chameleon 3 camera were used.
