Abstract
The photoelectric light curve of HR 7308 in mid-1981 is given and discussed. The total amplitude is 0.385 magnitude, the largest value yet observed, and the light curve is non-sinusoidal. The observations support a modulation period of 1210 days, but they do not support a model based on the beating of two close periods.
