Variations of the beta index of HD 101065 (Przybylski's star) with an amplitude of about 0.0007 mag and a period of 12.15 min have been verified. The Lafler-Kinman method, the power spectrum method as published by Deeming and the phase-dispersion-minimization method as developed by Stellingwerf were applied to the 510 observations and the results were compared.
