Scientific paper
The authors present experimental data on the electron and proton fluxes recorded on board the Prognoz-3 satellite in 1973, data on the parameters of the solar wind and the interplanetry magnetic field and the GCR fluxes recorded by various neutron monitors, and also data on the magnetic storms and the Kp-index. They analyze the preflare situation that is observed during one or two solar rotations prior to a flare. It is shown that this period is characterized by the apperance of active regions on the Sun, by the generation of coronal formations and their expulsion into interplanetary space, by the appearance in interplanetary space of ordered magnetic structures that are filled with electrons and protons, and by reduction of the GCR fluxes. The preflare situation is also characterized by intensification of the activity of terrestrial origin. The magnetic activity intensifies in certain regions, both on the Earth and on the Sun, as a consequence of which the amplitudes of the magnetic storms in these regions intensify and particles that can be recorded by neutron monitors are generated. Perturbation of the Earth's magnetosphere takes place in these periods, as a result of which there appear in interplanetary space protons with energy E ≥ 40 MeV of magnetospheric origin.
