Abstract
Characteristics of solar proton events during the periods of Sun’s magnetic field reversal in 19–24 solar activity cycles have been considered. In each of these solar cycles periods of time with duration of 8–12 months have been found, during which the number of solar events, total and maximal proton fluences were lower and the energy spectra were softer, than during the periods of equal duration before and after that. In most of the considered cycles the mentioned periods occurred after the cycle maximum or during the local “Gnevyshev minima”.
