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–

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.

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).

Plasma and magnetospheric research [PDF]

Research developments in the following areas are discussed: (1) an ion trajectory computer code which plots the paths of ions ejected from the polar cusp ionosphere; (2) the response of plasmaspheric ion temperatures to geomagnetic activity; (3 ...

Locating the magnetospheric ring current [PDF]

Protons are studied in the global depression of the earth's horizontal magnetic field. It is shown that 10 to 100 keV protons dominate ring current energetics in two preferred regions of cyclotron instability, which serve as stable trapping boundaries ...

A DE-1/whistler study of the thermal plasma structure and dynamics in the dusk bulge sector of the magnetosphere [PDF]

The objective of this research was to obtain new understanding of the thermal plasma structure and dynamics of the plasmasphere bulge region of the magnetosphere, with special emphasis on the erosion process that results in a reduction in plasmasphere ...

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 ...
