Propagation of Interplanetary Shocks Across the Bow Shock

Abstract

Using one IP shock observed by Geotail, we compare its passage through the magnetosheath with predictions of the global BATS-R-USMHD code. We demonstrate oscillations of the whole system with a period of 10-12 minutes.

Moreover, we suggest that the information about the IP shock hitting the subsolar magnetopause reaches the nightside magnetopause earlier than the IP shock can arrive.
