The paper describes a simple photoelectric photometer for the observation of occultation. Also discussed are some design problems, including the relation between measurable magnitude, signal-noise ratio and integrating time, the effect due to brightness of background, and the requirement of frequency bandwidth of the photometer. As a test, the instrument was used to observe the occulted event of star AGK+19 deg 0599 by asteroid (65) Cybele on Oct. 18, 1979 and a successful result was obtained.
