Abstract The authors report the observation by Akebono, on several occasions, of the precipitation of a nearly monoenergetic band of ions in the magnetosphere inside the polar cusp at altitudes of 8000 to 10000 km. This band extends over several degrees in latitude, and is often observed in conjunction with solar rain electrons, and appears to have a beam-like energy of 0.7 to 2 keV, with fluxes of 10{sup 6}(cm{sup 2}s){sup {minus}1}, and densities near 10{sup {minus}2}cm{sup {minus}3}. They suggest these ions the the energetic component of the solar wind swept into the magnetosphere from the magnetosheath.
