                FLARE STARS IN ORION



  We have continued the survey for flare stars in the region of
the Orion nebula. On the plates taken with the 40 inch Schmidt
telescope of Byurakan. Astrophysical Observatory we discovered
nine flare events of the stars around the Orion nebula.
  The effective coverage of these observations was about 32
hours in the U-band and the method of observations was the common
one of multiple and equal exposures of 5 minutes.
  Table I gives the data for the nine flare stars found. The
Haro and the Parenago numbers are also given, the coordinates
and magnitudes are approximate.
