AMPTE/CCE He+ and H+ observations in the magnetosphere, low latitude boundary layer, and magnetosheath reveal that cold (~tens of eV) plasmaspheric He+ distributions from the outer magnetosphere convect into the low latitude boundary layer. In the boundary layer, the cold He+ is accelerated and heated to a few keV. The data are resolved in sufficient detail to show that the process of pick up of the cold He+ distribution in the boundary layer H+ flow may not be adequate to explain the observed He+ distributions in the boundary layer. ¿ American Geophysical Union 1989
