Abstract The results of the detection of repeated bursts of gamma rays with energies exceeding 30 MeV from the June 15, 1991 solar flare, observed with the Gamma-1 telescope, are examined. It is shown that they occur on the declining part of the temporal profile of the gamma radiation and last for ∼10 min (they occur 27 min after the optical part of the flare starts). No appreciable radiation bursts were observed during the subsequent quasiconstant part (∼20 min). It is concluded that repeated events in which particles are accelerated occur in the active stage of the powerful June 15, 1991 solar flare. It is noted that while the June 15, 1991 and March 26, 1991 gamma-ray bursts share a common character, their spectral and temporal characteristics are substantially different.
