HR 8752 is a G5 hypergiant in the Cep OBI association. It is an SRd variable according to the GCVS. The V and B-V curves of the star are plotted in Figure 1. One point in the figure is the mean of all measurements made in a ten-day interval. The circles contain the observations of Arellano Ferro (1985) which show large deviation in two cases. Neglecting these circles, it is clear from Figure 1 that HR 8752 has alternating brighter and fainter maxima, the difference between them being some hundredth of magnitude, A possible explanation will be outlined for this phenomenon.
