             NEW FLARES IN THE PLEIADES


Seven new flares were discovered in the Pleiades with the 60/90/180
Schmidt-type telescope at the mountain station of the Konkoly Observatory in
the period from September 1971 to March 1972 in 26 hours of effective
observational time.

The observations were made on Kodak OaO (flares No. 1-3) and 103a-O (flares
No. 4-7) emulsions. The multiple exposure photographic material comprises
360 different exposures (4 minutes each). There are 8 exposures on every
plate.

Table 1 summarizes the following data of the flares: position, brightness in
minimum, amplitude and date of the flare. Figures 1-7 show the
photographically measured magnitudes during the flares. (Numbers at the top
of the columns are the serial numbers of the exposures on the plate.)
