AR12648 in Ha - 11th April

This little active region is barely a patch of plage in Calcium light, but in Ha remains pretty interesting!  Looks like a wave of plasma washing over it.  Taken with the 100mm Tal100R refractor, double stacked Daystar Quark and PGR Chameleon 3 using 2x2 binning in an attempt to tame the seeing.  Given the thick haze all day i'm very pleased with the result!
