Transient Micropulsation Signals

During the last 4 years a number of developments have occurred which have led to an increased understanding of the role of wave phenomena in the physical processes of the magnetosphere. While the studies span the frequency regime from millihertz to the electron gyrofrequency, the developments to be discussed in this paper have in common that they have added substantially to the understanding of the controlling processes, regions, and boundaries in the magnetosphere. The topics discussed are the increased awareness and documentation of the role of the plasmapause in micropulsation generation and propagation; •he establishment of the role of ion cyclotron waves in the wave-particle interactions at the plasmapause; the discovery of magnetospheric electrostatic waves with w --(3/2)•_; the discovery and preliminary identification of the source of plasmaspheric hiss; and the analysis of storm time Pc 5 waves as observed on the satellites ATS 1 and Explorer 45. 960 1715 1720 1725 SlPLE (L:4.0) GIRARDVILLE (L=4.4) LAC REBOURS (L = 4.0) DURHAM (L=3.2) 1730 SIPLE GIRARDVILLE LAC REBOURS DURHAM 730 SIPLE GIRARDVILLE LAC REBOURS

Transient Micropulsation Signals

Abstract: During extremely quiet magnetic times, transient magnetic signals have been observed which differ significantly from any previously reported. They can be interpreted as being due to a travelling bunch of charged particles (for which two models are discussed), or to meteors.
