Ha Full Disk - 6th August

Up early as usual, we're in unsettled air with jet stream Atlantic weather blowing in, and experience suggests there's normally a brief window of clear skies just after dawn and just before the heat of the sun gets convection going and clouds bubbling up. This was indeed the case and only had enough time for a couple of full disks, first off things in Ha with my preferred setup of Lunt50 etalon, 60mm f6 scope, Daystar Quark, 0.7x solar telecompressor and FLIR GH3 ICX916M camera. Where we had the emerging flux region yesterday seems to have quietened right back down now, but is still quite bright compared to the background disk. A few brighter points in lower southern latitudes mark the tell tale sign of the cycle 25 jet stream, and a few very small proms and filaments are about it for today.
