    A NEW LIGHT CURVE OF THE ECLIPSING VARIABLE W UMa


    Photoelectric observations of W UMa (BD +56d1400, HD 83950)
in two colours B and V were made with the 48 cm Cassegrain telescope 
equipped with a 1P21 photomultiplier tube at the Ege University 
Observatory between February 23 and February 25, 1979.
BD +56d1399 was used as comparison star during the observations.
    The light curve is shown in the Figure where the individual
magnitude differences between the comparison and the variable
star have been plotted against the phases which were calculated
with the elements given by Cester and Pucillo (1972) as:
      Hel Min J.D. - 24 35918.4154 + 0.33363808d E.
    The analysis of the light curve is in progress.
