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.
