Time evolution of the secondary cosmic radiation during the magnetic storm of 20 August 1979

Approximately periodic variations were detected in the electron, proton, and ν intensities by the Nataliya-1 gamma telescope during a flight on a high-altitude balloon at 46 0N. The periods of these variations were approx.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
