        PHOTOELECTRIC OBSERVATION OF W UMa (BD+56d1400)



  This well known eclipsing variable has been observed for the last four
months. Here we present the latest light curve obtained on April 6, 1982 at
the Ege University Observatory, Izmir. The 48 cm cassegrain telescope and a
single channel unrefrigerated photometer was employed. In Figure 1, the light
curves obtained in B and V colours respectively are presented. The phases
were calculated according to the light elements:


        JD Hel Min I 2444986.3624 + 0.33363808d.



The minimum times are,


        JD Hel Min I     2445066.4356
        JD Hel Min II    2445066.2689

                        [FIGURE 1]

 Figure 1. The light curve of W UMa in B and V colours, obtained on 
 April 6, 1982

In this time of the observing season the primary minimum comes first and
the secondary one appears later, therefore in order to present a continuous
light curve the secondary minimum is drawn first.
