Abstract : This paper relates to the interpretation of photographs taken at the Lockheed Solar Observatory with an H-alpha filter having a pass band of 0.5 Angstroms. Photographs taken at the line center refer to higher atmospheric levels than do those taken in the wings. The program of solar photography at Lockheed has featured the taking of records in rapid sequence at 10 sec intervals. Records taken approximately 0.5 Angstroms to the red or violet of the line center are relatively free from the complex bright and dark plages characteristic of chromospheric and prominence activity.
