Abstract

We analyze ACE observations of 47-66 keV ions for many strong interplanetary shocks seen from 1998-2003. We find that for nearly all-27 out of 30-of the strong shocks we analyzed, suprathermal ions were seen to be enhanced at the time of the shock passage. We find that many of the observed time-intensity profiles are consistent with predictions from the theory of diffusive shock acceleration. Our results suggest that shocks are efficient accelerators of suprathermal ions.
