              FLARE STARS IN PLEIADES

  Continuous photographic observations of the flare stars in the Pleiades
region have been carried out at the Bulgarian National Astronomical Observatory 
during August-December 1982.
  The photographic patrol has been made with the 20in./28in. Schmidt telescope 
at Rozhen in U-light (ORWO ZU21 plates with UG2 filter).
  Three new flare stars and four flare-events of known flare stars have
been discovered for 36h30m total effective time of observations.
  The data of observed flares are given in the Table.

  The Rozhen designations for the Pleiades flare stars according to
M. Tsvetkov et al, (I.B.V.S. No. 2224) have been continued.
  The identification of the flare stars was given by Haro et. al. (Bol.
Inst. Tonantzintla, vol. 3, No. 1, 1982).
