                MV LYRAE AT MINIMUM LIGHT IN MAY 1988

The cataclysmic binary MV Lyrae, included in our research programme of
VY Scl systems, was observed in May 1988. On three plates taken with the
50/70 Schmidt telescope of the National Astronomical Observatory Rozhen on
the nights of May 17/18 and 19/20, MV Lyr was at minimum light. The magnitudes 
determined according to the magnitude scale given by Andronov and
Shugarov (1982) are as follows:

JD 244..        B

7299.511      17.26
7301.537      17.18
7301.560      17.21

   Our programme of the observation of the star is going on. The observations, 
both spectroscopic and photoelectric, with short time resolution in
minimum are urgently needed for comparison with the results of Robinson et al.
(1981).
