A Satellite Study of DC Electric Field Reversals in the Magnetosphere.

Abstract

The paper reports on the convection electric fields observed with the double-probe type DC electric field experiment on the low altitude (677-2528 km) polar orbiting Injun 5 satellite. Simultaneous measurements of antenna impedance by the spacecraft make it possible to investigate in detail the operation of the electric antenna system and errors caused by sunlight shadows on the probes, wake effects, and other factors. Electric field magnitudes as small as plus or minus 10 mV/meter can be measured under favorable conditions. A summary pattern of >0.75 km/sec polar thermal plasma convection is presented. (Author)
