Low energy (>130 eV) oxygen ions at the geosynchronous orbit during the CDAW 6 event of March 22, 1979

Anisotropic O/sup +/ ions were frequently observed by the GEOS 2 ion composition experiment in the energy range 4--130 eV, during the CDAW 6 event of March 22, 1979. These observations allow the study of the plasma flow in the electric and magnetic fields as known from data of other experiments in the geosynchronous orbit, in the noon, dusk and midnight sectors. By comparison of these measurements with plasma observations made by the ISEE 2 plasma experiment, at the same local time and a different latitudes, the observation of cold plasma streaming along magnetic field lines from the polar ionosphere to the equatorial magnetosphere is extended from the magnetotail to the near earth equatorial region.
