Abstract: 
Recent photoelectric data on the W UMa systems LZ Her, ER Ori, YY Eri and RZ Tau are reported. Linear and quadratic ephemerides are determined from the times of minima obtained in the present paper and those compiled from the literature; the rates of change in the periods are calculated from the quadratic terms in the ephemerides.
