The plasmapause revisited [PDF]

open access: yes
Saturation of the dc double probe instrument on Explorer 45 was used to identify the plasmapause. A data base was developed to statistically study the average position of the plasmapause over 14.5 hours of magnetic local time under differing magnetic ...

Identifying the Magnetospheric Drivers of Giant Undulations: Global Modeling of the Evolving Inner Magnetosphere and Its Auroral Manifestations

open access: yesGeophysical Research Letters
We present the first global geospace simulation to reproduce auroral giant undulations (GUs). To identify their magnetospheric drivers, we employ the MAGE (Multiscale Atmosphere‐Geospace Environment) model in a case study of a geomagnetic storm for which

Studies of the structure of the plasmasphere as seen by radiosounder measurements aboard the Alovetti-satellite [PDF]

open access: yes
The structure of the plasmasphere was studied as seen by radiosounder measurements aboard the Alovetti-2 satellite. Magnetic tape data files were obtained from the NASA Ames Research Center to give a reasonably complete set of high latitude electron ...

Explorer 45 (S 3-A) observations of the magnetosphere and magnetopause during the 4-5 August 1972, magnetic storm period [PDF]

open access: yes
The Explorer 45 satellite performed extensive field and particle measurements in the heart of the magnetosphere during the double magnetic storm period of August 4-5, 1972.

Giant Undulations Driven by Pitch‐Angle Scattering of Time Domain Structures Modulated by Plasmapause Surface Wave

open access: yesGeophysical Research Letters
Plasmapause surface waves (PSWs) near the plasmapause boundary are regarded to be the magnetospheric source of ionospheric auroral giant undulations (GUs) located at the equatorward boundary of diffuse aurora.

ULF Wave Characteristics in the Auroral Zone through the Plasmapause

open access: yesAntarctic Record, 1979
Geomagnetic pulsations in the auroral zone through the plasma-pause were examined on the basis of IMS observation data obtained in Canada. It was shown that the geomagnetic pulsations in the daytime are reasonably accounted for in terms of HM waves ...

The simulation of the geosynchronous Earth orbit plasma environment in Chamber A: An assessment of possible experimental investigations [PDF]

open access: yes
The possible use of Chamber A for the replication or simulation of space plasma physics processes which occur in the geosynchronous Earth orbit (GEO) environment is considered.

Radiation belt electron acceleration by chorus waves during the 17 March 2013 storm [PDF]

open access: yes, 2014
Local acceleration driven by whistler-mode chorus waves is fundamentally important for accelerating seed electron populations to highly relativistic energies in the outer radiation belt.

Isolated cold plasma regions: Observations and their relation to possible production mechanisms [PDF]

open access: yes
Regions of enhanced cold plasma, isolated from the main plasmasphere along the Explorer 45 orbit on the equatorial plane, are reported using the sheath induced potentials seen by the electric field experiment. The occurrence of these regions has a strong
