Scientific paper

An interplanetary shock caused by a solar flare reached Earth at 13:22 UT on July 29, 2002. The sudden impulse connected with the shock was observed by Geotail, GOES 8, GOES 10, and Polar in the equatorial dawn magnetosphere. We compare numerical results obtained by BATS-R-US, OpenGGCM, and LFM magnetosphere models with the observations. The models predict some features of the interaction, such as for example the inward magnetopause motion. The spacecraft and ground observations show that the sudden impulse initiates quasi-periodic low-frequency electromagnetic pulsations with periods of several minutes. After the shock arrival, Geotail enters the magnetosheath where it observes similar pulsations during next 10 minutes. We think that these magnetosheath pulsations are connected with radial magnetopause motion associated with compressional mode oscillations between the magnetopause and inner boundary.
