AB: Geomagnetic cutoff variations during several storms are numerically determined using trajectory computations in fields from (1) the Tsyganenko 2005 geomagnetic field model and (2) the Lyon-Fedder-Mobarry MHD magnetospheric simulation code. The modeled cutoffs are compared with observed cutoffs obtained from SAMPEX energetic ion data.
