Description
Summary:Analysis of experimental data on the variations in the intensities of 2–12 MeV electrons and cosmic rays and the interplanetary magnetic field (IMF) magnitude has revealed “responses” to the influence of Jupiter in these parameters. Their amplitudes, in instrumental count units, are the following: 0.15 (71%) in the electron intensity, 48 (0.8%) in the cosmic-ray intensity, and 0.19 (2.8%) in the IMF magnitude. The maximum of the response in the electron intensity and the minimum of the response in the IMF magnitude coincide and lie near the magnetic field line that runs along the Sun-Earth-Jupiter axis. The minimum of the response in the cosmic-ray intensity is shifted against the solar rotation by 75 days from the magnetic field line connecting Jupiter and the Earth. Jupiter has the strongest influence on the intensity of high-energy electrons (71% of their total intensity).
