Energetic Magnetosheath Ions Connected to the Earth's Bow Shock: Possible Source of CEPs

Abstract

Plasma and magnetic field data detected by NASA GGS/POLAR and WIND during the May 4, 1998 storm event are analyzed to demonstrate for the first time a causal relation between the magnetosheath energetic ions and bow shock magnetic geometry. Intense magnetosheath energetic ions observed upstream from the cusp are from the quasi-parallel bow shock and show properties indicating that they are a possible source of cusp energetic ions (CEPs).
