Photoelectric observations of novalike MV Lyr in a standard UBV system were carried out at Rozhen and Belogradchik observatories in 1992 and 1993. During all the nights of observations the star was in high state (V∼12.5mag). The observing runs performed in U and B bands show strong flickering activity and a typical shape of the red noise power spectrum. The periodogram analysis of time series shows quasi-periodic oscillations with a period of about 50min. The excitation of trapped oscillations at the outer edge of the accretion disc, has been proposed as a possible mechanism for generation of MV Lyr quasi-periodic oscillations. The properties of the flickering in MV Lyr light curves were determined.
