000002598 520__ $$aNew CCD VRI light curves and time-series analyses of the Algol-type eclipsing binary VV UMa are presented. Our new observations have been analyzed using the Wilson-Devinney code from which new geometric and photometric elements are derived. A time-series analysis of the residual light curves in the filter I indicates pulsations of the primary component with a main frequency of 17.24 c/d and a semi-amplitude of 0.003 mag. A parallel analysis of the residual light curves in the filter R indicates a main frequency of 16.50 c/d (alias of previous one), which confirms the preliminary result obtained in the I band. There is a slight possibility of multiperiodic behaviour, but the present data are too scarce to be certain.
