This heat wave needs to stop.  Already 90 degrees at the end of my observing session!  Solar activity is Very Low with no C-class flares in the last two days, although AR2555 has been busy with B-class flares. Two Active Regions today with a total area of 340 millionths and a total count of 6 spots.  AR2553 has been an alpha area since it came around the Western limb, and was classified continuously, except for the first day,  as an Hhx area.  In addition to the nice filaments around AR2553, we have a beautiful arching Prom at the NW limb and a new spot emerging in the West.
