 Saturday
            was my day to get up super early and put in a 20 mile training
            run to supplement my marathon training endeavors. So by the time
            I got back and cleaned up, it was near 11am, and the seeing was
            getting pretty shaky from the day heat. I still managed to get
            one full disk Cak, and several Ha shots here. Seeing is always
            much worse in the blue and UV, so the calcium shots with the
            barlows were not useable. but the red hydrogen shots held up
            fairly well, and you can see some nice proms here. 


            
I will add that
            I am slowly and painfully learning about taking and processing
            solar monochrome images. Here and from now on, I have learned
            how to not burn out the prominence shot that is the backdrop
            for the disk shot and now you can see all the way down to the
            disk the spicule features! Oh what fun.

The view
                  in Calcium K light (Near UV) reveals the two huge spot groups,
                  and several minor ones. AR1289 our friend from the past weeks
                  which has provided northerners some aurora, is now on the very
                  edge of the disk at about the 2:00 o'clock position here. It
                  may come back or this may be its last hurrah!

AR1294
                  moving off with a bang - here you can see it flaring a bit, and
                  also a nice flame like prom. the red rim in all my images is
                  real - its the forest of spicules that I have now learned not
                  to overexpose!

                  looks to me like two eyes


                  
of
                  a brine shrimp.  It is flaring slightly here  too

AR1295/6
                  is now coming onto the center of the disk and is a powerhouse
                  of flares!
