The Sun’s activity today is medium with 10 C-class flares in the last two days.  Total Sunspot area has decreased from 120 to 110 millionths and the total sunspot count now stands at 16 in four active regions.  Today’s images are a Ha and CaK image made in the morning using my equipment, and a full disk image and close up of AR2434 made at a first light imaging session at Covington’s Perimeter College, with their new Coronado 90mm.  I like the results.
