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 determin ed from the times of minima obtained in the present paper and those co mpiled from the literature; the rates of change in the periods are cal culated from the quadratic terms in the ephemerides.
