      FLARE STAR OBSERVATIONS IN NGC 7000 AND IC 5070

 Here we present some results on the systematic search of flare stars in
the NGC 7000 and IC 5070 region.
 Our observations were carried out with the 40in./52in. Schmidt telescope
of Byurakan Astrophysical Observatory of the Armenian Academy of Sciences
(USSR) and with the 20in./28in. Schmidt telescope of the Bulgarian National
Astronomical Observatory at Rozhen during August 1979 to August 1980.
  The data of observational material are given Table I.
