Results are reported for UBV photoelectric photometry of the A2p Sr-Cr-Eu star 53 Cam (equals AX Cam equals HR 3109 equals HD 65339). It is found that two cyclic variations in brightness with respective periods of about 1.1425 and 8.0 days appear to be present in the star's B and V light curves. It is suggested that the 1.1425-day period might be an aliasing effect, since the sum of both frequencies almost corresponds to one day.
