            PHOTOMETRY OF WZ Sge


   WZ Sge was observed shortly after its 1978
outburst using the 36" Yapp reflector at RGO equipped
with a "People's Photometer". Simultaneous B, V
measurements were made in the sequence sky-comp-sky-
WZ-sky-comp-sky under rather poor conditions, with an
integration time of 20^s; star 'c' of Krzeminski and
Kraft (1964) was used as the comparison.

                    [FIGURE 1]

   The results are shown in Figure 1. The V amplitude
approaches 0.2m and a broad primary minimum is present,
approximately in phase with the pre-outburst ephemeris
(Robinson et al., 1978) shown in the figure. There is
some evidence for the flickering reported by McGraw and
Patterson (1978) but nothing quantitative can be said
because of the poor sky conditions.
