 Today
            the sun had an extraordinary amount of filaments on the disk
            - proms seen in silhouette against the sun. The sunspots or as
            we call them in Halpha imaging - Active regions were plentiful
            and some had some small flaring action. The Proms along the limb
            were faint, but had some interesting details as we zoomed in.

Next
            we zoom into the individual regions with the 3x Klee Barlow,
            resulting in a 6x increase over the above image. 

            


            


            


            


            


            


            


            
Next,
            we increase the exposure and lower and gamma to see the prominences
            on the limb. 

            


            


            


            
Finally,
            we go off band about 3/4 Angstroms into the "Red wing of
            Halpha" to see the white micro flares around the sunspots
            known as "Ellerman bombs"
