A coordinated satellite and groundbased study of an intense electron precipitation spike over the southern polar cap.
01 January 1984
An electron precipitation event has been investigated with bremsstrahlung x-ray mapping data taken from two satellites and with groundbased riometer and magnetometer data. The event occurred near 2300 UT on 27 June 1982 in the vicinity of South Pole Station which was in the dusk-midnight local time sector. The main precipitation was associated with a poleward-moving westward electrojet and produced the largest riometer absorption (exceeding 10 dB at 30 MHz) recorded during 1982 at that station.
