CaK Full Disk Animation 7th June

Even when solar activity is low, the surface never stops boiling away with endless plasma convection cells as can be seen in this image taken with the 40mm scope at 650mm focal length with the homebrew CaK filter and the PGR Blackfly GigE IMX249 camera.  The animation spans approximately 15 minutes with one frame every 3 minutes.
