Had some time, and clear skies for an imaging session. (Seeing 7/10) The Sun’s activity is down again and low. Total spot area went down from 510 to 470 millionths while the sport count went up by 1 to 34. Total flares in the last two days was limited to 1 C-class flare. Today, three full disk images and close ups of AR2439 with a nice prominence, and AR2435.
