Departing Active Regions CaK - 13th June

A closeup of the active regions that have been threatening to flare over the last week as they approach the western limb.  Proms are visible as a hazy cloud over the limb showing that these active regions are 3 dimensional features and not just features on the 'surface' of the sun.  Taken with the 40mm at 700mm focal length with the DMK31 camera.
