Intensity-time profile and shock interaction with the interplanetary magnetic field of SEP events associated to eastern events. (a) The intensity-time profile of the SEP event that occurred on 6th December 2006 (from NOAA/SWPC). The solid red, blue, and green fluxes represent a typical evolution of the integral proton fluxes for eastern events with energies >10, >50, and >100 MeV, respectively. (b) The CME propagation direction and particle transport for the peak of the event as seen close to the Earth are shown.
