We present the results of a three-year Johnson V and Strömgren uvbyHβ photometric study of the δ Scuti star BR Cancri (BR Cnc). Our data sets consist of 1293 discrete differential magnitudes in Johnson V and yellow y filters, 883 in Strömgren v and 239 in ub filters. The Fourier analysis of the data suggests four pulsation frequencies for the variable: f₁=24.978, f₂=11.358, f₃=11.808 and f₄=27.914cycle.d^–1. During the three observing years, the main frequency f₁ kept its V(y) amplitude constant at about 6mmag but its v amplitude seems to be changing. Amplitude variations for all the three other frequencies are also claimed. The pulsation modes of the frequencies are discussed based on the colour data. Using uvbyβ data and calibrations in the literature, we derive the physical parameters for BR Cnc.
