Ha Full Disk 2nd August

You have to look carefully at the moment as we head towards solar minimum for details on the sun, but today we have a newly designated active region, AR12717.  This has a small single spot with some signs of pores around it.  It is Quite bright in Ha light.  Also visible is a small emerging flux region with signs of the magnetised plasma churning around.  The rest of the disk is essentially blank.  Taken with the double stacked Lunt50 etalons, BF15, PGR IMX249 camera.
