Ion entry into the magnetosphere was studied for different interplanetary magnetic field (IMF) orientations. Field models for the study of ion entry were from the results of global magnetohydrodynamic (MHD) simulations. Ions entering under northward IMF conditions entered on reconnected field lines and entered the flanks of the magnetotail. Some were strongly accelerated during entry at high latitudes. Under southward IMF conditions particles entered through the plasma mantle and only ...
