A phase dispersion minimization method is used to perform a frequency analysis of Van Hoof's photometric observations of the β Cephei star, ν Eridani. The frequency analysis reveals the existence of four oscillations in the light variability of p Eridani. In addition to the primary largest amplitude oscillation with frequency f0 = 5.76349 c/d, three oscillations have been detected with closely spaced frequencies : f1 = 5.6373 c/d, f2 = 5.6535 c/d, f3 = 5.6201 c/d. The present numerical values of the frequencies are in good agreement with the values obtained by Saito and Kubiak from a frequency analysis of radial velocity data.
