Scattered clouds with poor seeing this morning.  NOAA’s SWPC did report another spotless day in their GEOAlert last night, which counted in my database as the 902nd spotless day since Solar Max.  According to SWPC, the region in the SE quadrant has shown over the last few days a number of pores, which decayed very fast.  Today I could make out two of them in my 540nm close up.  In addition there are numerous prominences all around the Sun.  Today full disk images and close ups of the mentioned areas.
