Scientific paper

The sawtooth event on April 18, 2002 occurred in the middle of a multiply-peaked magnetic storm, and includes at least six strong energetic electron and proton injections that were observed near-simultaneously at all local times. Magnetic field measurements for this event are available from the GOES and Geotail spacecraft, and the LANL MPA electron measurements were used to infer the field inclination at multiple locations at geostationary orbit. We use empirical magnetic field modeling techniques to reconstruct the time evolution of the magnetospheric current systems during the sawtooth oscillations. The model results are compared with current systems during other sawtooth events as well as those that prevail during isolated substorms. We trace energetic ions in the time-evolving magnetic field model to demonstrate how the very strong current near geostationary orbit affects particle orbits. The current that peaks strongly in the evening sector leads to strong losses at the dayside boundary and thereby limits the ring current intensification.
