               FLARE STARS IN ORION


   Twenty-two new flare stars (Table I) and 8 repeated flares
of known flare stars (Table II) had been revealed, while continuing 
the photographic observations in the Orion nebula region
with the Abastumani Observatory 70-cm Meniscus-type telescope,
using the multiple exposure method.
   Table I and II give the data of these flares. We are 
continuing the numeration of flare stars.

   Out of all registered flares Nos 79, 80, 83 are slow ones,
the brightness of which had increased during more than 
40 minutes.
    In Table II the flare stars identified with Tonantzintla
(1), Asiago (2) and Abastumani (3) lists are denoted by T, A and
Ab, respectively,
    Outbursts numbered 6 and 7 of the star T8 took place within
the time interval 3h 35m. These outbursts are presumably the 
result of the same flash-activity cycle.

    Finding charts are given.
