Anisotropies and streams of solar and galactic cosmic rays in the inner heliosphere

Temporal changes of the anisotropy and energy spectrum of solar cosmic rays have been analyzed based on the experimental data of the neutron monitors and meson telescopes data (among them for the event of 29 September 1989) and the solutions of the Fokker- Plank equation included adiabatic focusing. Parker's three dimensional transport equation of galactic cosmic rays has been solved using diffusion coefficient found from the peculiar behaviors of the solar cosmic ray intensity. Spatial distribution of the anisotropy and streams of galactic cosmic rays of 10 GeV energy range have been calculated and compared with the experimental data of neutron super monitors. It is shown that a realistic diffusion coefficient for which the solution of the transport equation is compatible with the experimental data must be only two-three times greater than that obtained from the power spectral density of the interplanetary magnetic field fluctuations; for this purpose the lower frequency limit 10-6Hz must be extended to left up to 5x10-7Hz. Distributions of the streams of galactic cosmic rays in the three dimensional inner heliosphere has been found for different epochs of solar magnetic cycles; for the Earth orbit there is included the drift effect due to the sector structure of the regular interplanetary magnetic field.
