Abstract:
On May 29, 1996, the Polar spacecraft appeared to cross into an extended cusp or magnetosheath region. The region was characterized by intense fluxes of ions in the energy range 1-10 keV that had solar wind like ion composition and angular distributions that showed evidence of flows and structure. These ion composition data are combined with energetic proton observations from Polar and plasma observations from the HEO 95-034 and DMSP satellites to examine the spatial extent and plasma characteristics of this region. The ion composition is consistent with expected solar wind composition. The combined spacecraft observations indicate a considerable spatial extent for the observed region, which may be produced by northward IMF interacting with the northern cusp.
