Finally, the clouds are mostly gone, but the temp at after one was 99.9 degrees when I took the measurement for my analemma project.  The sun’s total sunspot area increased 370 millionths from 420 yesterday to 790 today of which AR2403 covers already 760 by itself.  Activity is high and AR2403 at this time has already produced two M-Class flares today.  Sunpots have increased from 52 to 73.  The seeing was very good today 8/10, so I spend some time capturing WLC filtered images on the SVC as well as the C11.  The sky was calm enough to let me capture a close up again with very nice detail, this time of the “following” sunspot in AR2403.
