Another hot day with average seeing and great transparency.  AR2713 does not seem to give up since it increased to 20 millionths and 5 sunspots.  In addition, I noticed a pore, this time ahead of the region. Yesterday AR2713 did produce three small B1 class flares, but today it is off to a slow start with no flares yet.  Today two full disk images in CaK and 540nm as well as close ups of the mentioned areas.
