AB: During the period of enhanced geomagnetic activity, both the outer radiation belt electrons and plasmapause move toward the Earth. Are these just a natural consequence of enhanced solar wind interaction with the magnetosphere or are they intrinsically related? Recent studies indicate that the location of the plasmapause may determine the location of the peak in the outer belt electron intensity. Our study of long term satellite measurements shows that the inner edge of the outer belt electrons correlates well with the location of plasmapause. Combining data from SAMPEX, CRRES, Polar, IMAGE, ACE and ground magnetometers and modeling efforts, we will address the role of the plasmasphere in radiation belt acceleration and loss processes.
