Solar modulation of galactic cosmic rays with the ARINA and PAMELA spectrometers
Solar modulation of the proton flux in Galactic space radiation during the period from the end of the 23rd to the beginning of 24th cycle of solar activity is investigated using data from the PAMELA magnetic spectrometer and ARINA scintillation spectrometer. The time dependence of proton intensity is plotted, and shows typical features in a form of rises and falls against a main trend. In order to explain these, the correlation between variations in the Galactic proton flux and solar/interplanetary parameters is investigated.
