In 1984-1986 new observations of flare stars in the Pleiades region were carried out by the method of stellar tracks with 40″ Schmidt telescope of the Byurakan observatory. The effective observational time is 100 hours in U-rays (ORWO ZU-21 plates combined with UG-1 filter were used). The stellar tracks have 1-1.5 cm length, the limiting stellar magnitude on the plates is 13m-14m, time resolution is 5S-20s. 17 flares of 13 stars were detected. Six of these stars were detected as flare stars for the first time. According to the Hertzsprung catalogue all these stars are the Pleiades cluster members. The flare amplitudes reach up to 1.5-3.0 magnitudes, the duration vary from 2.5 to 10.5 seconds.
