AR12759 in Ha 7th April

This active region has been keeping us sun watchers happy for a while now, and while it is slowly rotating away from us should put on a good prom show on the limb.  There may be no sunspots associated with it anymore but it is still active, and even this morning was crackling away with very small scale flare activity.  Notice ahead of it and towards the limb small patches of brighter plage that are associated with the cycle 25 jet stream just below the solar surace.  This image was taken with the Coronado SM90ii double stacked with a Daystar Quark and using the PGR GH3 U3 916M camera.
