           FLARE STARS IN THE PLEIADES




  In September 1980 the photographic monitoring observations
in the Pleiades region were continued according to the joint
programme of investigation on the flare and nonstable stars in
the stellar aggregates between the National Astronomical Observatory 
of the Bulgarian Academy of Sciences and Byurakan Astrophysical 
Observatory of the Armenian Academy of Sciences. 10
plates with total time of effective observations 9h40m were
obtained with the 40"/52" Schmidt telescope at Byurakan 
Astrophysical Observatory.

  In Table I some informations about the observed flares are
summarized and the successive columns give the following data:
  1. Number of the flare star in the Pleiades according to the
    General Numeration
  2. Hertzsprung number
3.-4. Coordinates for 1900.0
5.-6. Photographic magnitude at minimum and amplitude of the
    observed flare in U-light
  7. Date of the flare event (U.T.).
