Ha Full Disk 6th July


It has been a while since i've seen a full disk with quite so much activity as this one, yes there are no sunspots or active regions, but there is plenty of plage activity and filaments that show signs of cycle 25 magnetism just below the surface at the higher latitudes, there is even some relic cycle 24 activity floating around the equator.  All this is a positive sign the solar doldrums are slowly going behind us.  Taken with a Lunt50 etalon double stacked with a Daystar Quark on a 60mm f6 scope.  A Baader solar telecompressor was used to get the image on the chip of the FLIR Grasshopper 3 camera.
