New Active Region AR12373 in CaK - 28th june

The sun looked like it was going to be blank at the start of the weekend, however by the end of the weekend a new active region ar12374 had given us a small spot and emerging flux region mid disk, and over the limb several larger sunspots had appeared in the form of ar12373, which although apparently quiet has had some surge proms associated with it suggesting it is not dormant.  This shot was taken with the ED60 at 1500mm focal length with the homebrew CaK filter and the PGR Blackfly GigE IMX249 camera.
