Magnetospheric electron density measurements from upper hybrid resonance noise observed by IMP-6 [PDF]

A band of natural radio noise between the local electron plasma frequency and the upper hybrid resonance frequency is observed by the IMP-6 satellite. The band exists over a large range of geocentric radial distances extending from inside the plasmapause

Magnetosphere–Ionosphere Conjugate Harang Discontinuity and Sub-Auroral Polarization Streams (SAPS) Phenomena Observed by Multipoint Satellites

Atmosphere
It is well understood that near midnight, the Harang Discontinuity separates the auroral duskside eastward electrojet (EEJ) and dawnside westward electrojet (WEJ) and associated plasma flows driven by enhanced magnetospheric convections via Magnetosphere–

A Model of Magnetic Pi 2 Pulsations Based on a ULF Obserbation from High- to Middle-Latitudes (d. ULF Waves in the Magnetosphere) (Proceedings of the Second Symposium on Coordinated Observations of the Ionosphere and Magnetosphere in the Polar Regions : Part I)

Antarctic Record, 1980
Spectral characteristics of magnetic Pi 2 pulsations are studied in detail by using data obtained simultaneously over a wide latitudinal range from the auroral region (L=8.9) through low-latitudes (L=1.8).

Dynamics of midlatitude light ion trough and plasmatails [PDF]

Light ion trough measurements near midnight made by the RF ion mass spectrometer on OGO-4 operating in the high resolution mode in Feb. 1968 reveal the existence of irregular structure on the low latitude side of the midlatitude trough.

The evolution of electron density and temperature distributions in the topside ionosphere during magnetic storms [PDF]

The latitudinal distributions of electron density and temperature during geomagnetic storms in the mid-latitude topside ionosphere are observed to change in a manner than can be related to the evolution of ring current particle populations. The region of

Proposal for an ionosphere/plasmasphere monitoring system

Annales Geophysicae
A space-based satellite system suited for long-term monitoring of the Earth's ionosphere/plasmasphere systems is proposed. The monitoring system consists of a network of radio beacon satellites capable of measuring the ionospheric and plasmaspheric ...

Micropulsations in the electric field near the plasmapause, observed by ISEE-1 [PDF]

The occurrence of micropulsations near and inside the plasmapause was surveyed. The observed pulsations, classified as Pc3 and Pi2, are discussed. In addition one single event of Pc1 was observed.
