Plasma Wave Observations Near the Plasmapause with the S3-A Satellite.
Abstract
The authors describe the electric field noise phenomena observed by the S3-A spacecraft near the plasmapause during the magnetic storm of December 16-17, 1971. The most striking and unusual feature of these storm time electric field observations is the occurrence of a region of intense low-frequency (2O Hz to 500 Hz) electrostatic noise bursts just outside the plasmapause boundary. These noise bursts occurred concurrent with the rapid decrease in 24.3 < or = E < or = 35.1 keV ring current protons mirroring near the equator during this storm and may be responsible for the pitch angle diffusion and loss of these particles. The characteristics of other phenomena, such as whistlers, ELF hiss, and banded chorus, observed near the plasmapause during this period are also discussed. (Author)
