            FLARE STARS IN THE PRAESEPE REGION



   The re-examination of all the multiple exposure photographic
material obtained during the years 1972 - 74 on the Praesepe region
has been carried out. The observations were made with the 24" Schmidt
telescope of Konkoly Observatory and with the 40" Schmidt telescope of
Byurakan Observatory.
  Seven flare-ups were discovered. The data of the discovered flare
stars are presented in Table I: the first column give the number of
flare, columns two and three gives the approximate coordinates for
1900.0, column four gives the minimum brightnesses in U - band, column
five gives the observed amplitude of the flare-ups in U - band, column
six the date of the flare-ups and column seven gives the remarks.
