            FLARE-UPS IN STARS OF THE PLEIADES FIELD

In course of searching for flares in the Pleiades five new flares
were observed during 7.6 hours of effective observational time in
the period from September 7, 1974 to March 18, 1975. Among the
stars flared up four new flare stars were discovered. The observations 
were made with the 24/36/72 inch Schmidt-telescope of the
Konkoly Observatory on Kodak 103a-O plates through a UG_1 - 2 mm
thick - filter. The exposure time was 7 or 10 minutes. The informations 
about our flares are summarized in the table.
Figures Nos. 1-5 show the brightness of the flares plotted against
time.
