Abstract:

Much work has been done to establish the finding that spacecraft charging at geosynchronous orbit is dependent upon local plasma conditions as well as geomagnetic activity. This paper describes further verification of correlations resulting from the analysis of a large data set from the geosynchronous satellite ATS-5 during eclipse passages. In addition, ground-ased geomagnetic indices were also compared with satellite potential, as well as individual magnetometer readings near the base of the geomagnetic field line nearest the satellite.
