Sunny skies with jet condense trails interrupting the session.  I made a mistake today in that I by accident checked the “cut” function in Firecapture which only captures a 300×300 pixel image instead of the entire solar disk. The result is that I did not get a full disk image in 540nm.  4 Hours before my images AR2703 produced a B9.0 flare but so far not a C-class flare.  Total Active Region area for today is 10 millionths with two sunspots, although it was very hard to make out the Active Region in 540nm.
