The top left panel shows the time evolution of an SREM measure (TC1, Buehler et al. 1996) which is sensitive to high-energy protons. The levels shortly after launch are also indicated (on the right), showing the passage through the van Allen radiation belts, characterised by very high count levels. The bottom panel (on the left) shows the corresponding evolution of the sunspot number, indicating the slow transition of the solar cycle out of its current minimum. A monitor of high-energy neutrons (in this case located at McMurdo station, data courtesy of Bartol Research Institute, supported by US NSF), presented in the middle panel, traces the corresponding decrease in the flux of Galactic cosmic rays as the Sun becomes more active.
