       PHOTOELECTRIC MOMENTS OF MAXIMA OF SZ Lyn



    According to the programme of investigations of dwarf
cepheids photoelectric observations of the variable SZ Lyn were
carried out in the years 1974-76. Within 12 nights over 500 
photoelectric observations have been obtained in the system close to BV
which made it possible to determine 10 maxima of light variations
in SZ Lyn in each colour.
    The epochs E and deviations (O-C) are estimated relative
to the ephemeris D3, GCVS, 1968:

    Max. J.D. = 2438124.3977 + 0.12053487 E.
    The moments of maxima and the deviations (O-C) observed
relative to the above elements are tabulated below:

       .4367   V   39408        +0.0009


    Deviations (O-C) confirm the conclusions made on the 
variability of the period of light variations in SZ Lyn with a cycle
of the order of 1146 days.
