Abstract

Distribution of energetic proton fluences in solar proton events during solar cycles 19–24 over the heliolongitude of their sources have been considered. It has been shown, that the major contribution into the total value of the fluence of protons with energies >30 MeV registered in the Earth’s orbit during the whole period of observations was given by the events, which sources were located near the central solar meridian.
