Daily Report
For Sunday, June 16 2016
 
 For
            a few days after a weekend monsoon storm, the seeing is very
            unsteady, and today was no exception. I shot the suns new sunspot
            in white light and calcium K. The six inch AR152 was used, stopped
            to 4 inches on the calcium images for better contrast at f/15.

 WHITE
            LIGHT:

            
Lets
            start with the full disk shot, you can see two small spots on
            each limb of the sun.

            


            
 

            
Next
            we zoom in with the 5x televue powermate. Seeing was 1.5 /5 which
            is not great but some granulation can be seen:

            


            
The
            second new spot on the limb now coming onto the disk:

            


            
 

            
In
            Calcium K light, which is in the near UV at 393nm the seeing
            is even worse! But always great details around sunspots in calcium:

            new bigger spot:
