AR12574 in Ha - 9th August

The active regions that have passed over the limb over the past couple of days form part of a huge group, so large that they won't fit in the field of view of the Airylab HaT.  These 2 spot regions were fairly static, but the small proms on the limb were very dynamic and would suggest more active regions on the way round in the days ahead.  I tried for an animation but the seeing was all over the place, and with passing clouds meant there weren't enough usable frames.  Taken with the 203mm scope at 5.6m focal length with a Daystar Quark and a PGR Blackfly GigE IMX249 camera.
