Abstract
A study is performed of solar proton events that occurred during periods of the reversal of the Sun’s magnetic field in cycles 19–24 of solar activity. Periods 8–12 months long and falling on the times of the magnetic field’s reversal are found in each solar cycle. The number of solar events and the total and maximum proton fluences are reduced during these periods, while the energy spectra are softer than those in preceding and subsequent periods of the same duration. In most of the considered cycles, the above periods begin after their maxima or during local Gnevyshev minima.
