Approximately periodic variations were detected in the electron, proton, and γ intensities by the Nataliya-1 gamma telescope during a flight on a high-altitude balloon at 46 °N. The periods of these variations were ~1, 10, and 30 min. Sharp surges in the intensities of these components were detected simultaneously. The time evolution of these events and their relationship to processes in the disturbed magnetosphere are discussed.
