Spatial Evolution Characteristics of Plasmapause Surface Wave During a Geomagnetic Storm on 16 July 2017

Geophysical Research Letters
Boundary dynamics are crucial for the transport of energy, mass, and momentum in geospace. The recently discovered plasmapause surface wave (PSW) plays a key role in the inner magnetosphere dynamics.

Plasma wave observations near the plasmapause with the S3-A satellite [PDF]

The electric field noise phenomena is described which was observed by the S3-A spacecraft near the plasmapause during the magnetic storm of 16 to 17 December, 1971.

Inner Magnetospheric Oxygen Torus Induced by Electromagnetic Ion Cyclotron Waves

Geophysical Research Letters
Cold oxygen ions escaping from the ionosphere and temporarily trapped near the plasmapause form the oxygen torus. Mass‐loading by these oxygen ions significantly affects magnetospheric plasma processes.

Characteristics of VLF Saucers Observed by ISIS-1, 2 Satellites

Antarctic Record, 1979
Characteristics of the saucer emissions are studied by using ISIS VLF data which were received at Syowa Station by the wintering party of the 17th Japanese Antarctic Research Expedition in 1976-1977. Saucers were observed most frequently in the nighttime

Solar-wind control of the extent of planetary ionospheres [PDF]

In our solar system there are at least four magnetic planets: Earth, Jupiter, Mercury, and Mars; while at least one planet, Venus, appears to be essentially nonmagnetic. The ionospheres of the magnetic planets are imbedded in their magnetosphere and thus

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.

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–

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

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).
