Title: Some aspects of the interaction of interplanetary shocks with the Earth’s magnetosphere: an estimate of the propagation time through the magnetosheath
Title of journal: Journal of atmospheric and solar-terrestrial physics
Series/Report no.: /66 (2004)

Issue Date: 2004

Keywords: magnetosphere, interplanetary shock
Abstract: We analyzed a number of forward shocks detected by Wind in the interplanetary medium to determine the orientation and speed of the shock fronts. Assuming a planar shock geometry and a constant propagation speed (both con9rmed by a comparison with available Geotail observations), we determined when the shock would hit the bow shock (BS) and evaluated the propagation time of associated disturbances between the BS and ground. We found delay times were ∼ 5 min: for almost radially propagating structures, this delay time would imply magnetosheath speeds of shock associated disturbances of ∼1/3 or 1/4 of the external shock speed.
