Daily Report
For Thursday March 30, 2017
 
 After
            weeks of a blank solar disk, the sun has produced a few fine
            sunspot groups for examination. Seeing this month has been some
            of the worst I have ever seen in Arizona, and today was no exception.
            Occasionally, I was able to see hints of granulation at 5x, so
            the seeing I rated at 1.5/5 for today. I have two sets here,
            the first in white light and the second CaK in near UV wavelengths.

            LIGHT:

            
Lets
            start with prime focus in white light with the AR152 stopped
            to 4 inches aperture:

            


            
The
            first of two groups at 5x at about 5 meters focal length:

            


            
Second
            group is less exciting:

            


            
However
            in calcium light both groups are far more interesting!
