Initial measurements of thermal ions (0 to 50 eV) at mid‐latitudes by the Retarding Ion Mass Spectrometer (RIMS) on DE‐1 are presented. These measurements show the plasmapause signature in H + , He + , and m/q = 2 ions, an enhancement or torus of O + and O ++ in the outer plasmasphere and the suggestion of a disconnection between the ionosphere and the bulge region of the plasmasphere.
