Abstract

Variations in energy spectra of solar and galactic protons with energies from 0.3 to 100 MeV were studied. From thg data obtained with various instruments aboard the IMP 8 spacecraft, 118 spectra were constructed for "quasi-stable" and "quiet" periods of solar activity in 1974-1991. It was found that the minimum in the spectrum shifts to higher energies as the solar activity increases during the solar cycle. As a rule, the flux of low-energy particles varies synchronously with the modulation of galactic cosmic rays.
