Daily Report
For Thursday, April 20, 2017
 
 After
            weeks of a totally blank solar disk, a new group has emerged
            on the limb. In calcium light the supergranulation cells are
            fantastic! Seeing was terrible - only 1.5/5 seeing. By stacking
            the best 25/1600 frames I was able to get some details.
