BON10 spectra of protons (top left), helium nuclei (top right), oxygen nuclei (bottom left) and iron nuclei (bottom right), for two extreme cases of solar activity. During solar maximum (dotted black line, ϕ = 1500 MeV) the flux of low energy particles decreases relative to periods of low solar activity (dashed black line), corresponding to a solar modulation parameter ϕ = 400 MeV.
