          PHOTOELECTRIC MINIMA TIMES OF VW CEPHEI

  Photoelectric observations of the eclipsing binary VW Cephei have been
carried out in September - November 1982 with the 50-cm telescope of the
Bucharest Observatory.
  The times of minima have been obtained with the Kwee and Van Woerden's
method (1956). The following ephemeris formulae have been used:

       Min (Hel. J.D.) = 2439348.415 + 0.278314d E            (1)

(Second Suppl. to the Third Edition of the GCVS, 1974)

       Min (Hel. J.D.) = 2433898.441 + 0.27831793d E          (2)

(Kwee 1966).

The Hel. J.D., the (O-C)1 computed with formula (I),(O-C)2 computed with
formula (2), the square mean error, the type of minima and the filter used
are given in Table I.
