AR12528 in Ha 5th April

This new little active region looked like it had the potential to develop a bit when I photographed it this morning, seemed to be crackling away on the smaller scale.  Taken with the 203mm Airylab HaT at 5.6m focal length, with a double stacked etalon (Daystar Quark and PST), with a PGR Blackfly GigE IMX249 camera.
