Departing Active Regions In CaK 14th August

AR12135 has been a bit of a damp squib for the time of its whole transit across the face of the sun, never doing very much at all, infact it has struck me over the last 2 weeks how little plage has been associated with this active region, which is something quite unusual to me.  The image was taken with the 40mm scope at 925mm focal length with the DMK31 camera.
