New Active Regions & Surge Prom in CaK 3rd June

A few more active regions have rounded the suns eastern limb now as can be seen in this shot taken with the ED60 at 1700mm focal length with the homebrew CaK filter and PGR Blackfly GigE IMX249.  As a bonus a small surge prom can be seen on the limb - maybe a sign of even more activity on the way round?
