Abstract: The data from the ion spectrometer aboard the OGO 5 vehicle have been analyzed for the early orbits. The profiles of O+, H+ and H+ ion concentrations have been obtained as a function of the geomagnetic parameter L. The detailed character of the plasmapause has been observed. It is found that the concentration change at the plasmapause location is highly variable being at times gradual and at other times very abrupt. The diameter of the plasmasphere is found to depend upon the magnetic activity, showing a significant decrease when the magnetic activity is high. The plasmapause is found to occur independently in all ion species at precisely the same location. An interesting ‘wavelike’ structure in the ion concentration is observed in the vicinity of L = 6.
