Abstract : Scintillation studies with the photoelectric photometer were continued but with some diversion of effort in motion picture photography of image motion and image pulsation. Successful movies of bright stars in noontime daylight were obtained, revealing a wealth of information on image form and motion in the daytime stellar image. Photoelectric studiea were extended to a close double star (Castor) and it was shown that the images of this close double (2.6 seconds of arc) scintillated independently of each other, whereas the motions and sizes of the individual components varied synchronously. Studies of artificial sources 1000 feet from the telescope were begun. (Contractor's abstract) (See also AD-21 921)
