Multi-satellite study of the excitation of Pc3 and Pc4-5 ULF waves and their penetration across the plasmapause during the 2003 Halloween superstorm [PDF]

Annales Geophysicae, 2015
We use multi-satellite and ground-based magnetic data to investigate the concurrent characteristics of Pc3 (22–100 mHz) and Pc4-5 (1–22 mHz) ultra-low-frequency (ULF) waves on the 31 October 2003 during the Halloween magnetic superstorm. ULF waves are

Local Evolution of a Prenoon Drainage Plume

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Plasmaspheric drainage plumes are typically observed in the postnoon sector during geomagnetic storms, but their local evolution in the prenoon sector remains poorly understood. Here, we report in situ observations from the Van Allen Probe, revealing multiple localized enhancements in cold electron density near apogee in the prenoon sector ...

An alternative interpretation of Jupiter's “plasmapause”

Geophysical Research Letters, 1976
It has recently been suggested that Io is an important source of ions for the plasma detected by Pioneer 10 in the inner magnetosphere of Jupiter. Assuming this to be true, we show that near the orbit of Io the central collector of the Pioneer‐10 plasma instrument could detect only inwardly diffusing ions created at a radial distance greater than that ...

A Statistical Study of Warm Plasma Cloak Particles Using Van Allen Probe Data

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The Warm Plasma Cloak (WPC) consists of ions in the inner magnetosphere with energies between 10 eV and 1 keV and showing a bidirectional pitch angle distribution of particles. These particles play an important role in wave–particle interactions and in controlling the dayside reconnection rate at the magnetopause.

Auroral patches in the vicinity of the plasmapause

Geophysical Research Letters, 1977
Unusual aurora‐like patches have been observed equatorward of the diffuse auroral boundary by the ISIS‐2 scanning auroral photometer. These rare features are observed predominantly in the evening sector and appear to corotate with the earth and to have lifetimes longer than two hours.

Extension, Improvements and Perspectives of the Cluster GRMB Data Set

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The purpose of the Geospace Region and Magnetospheric Boundary identification (GRMB) data set is to provide information on the regions crossed by each of the 4 Cluster spacecraft during the entire mission. The data set includes 15 labels, 11 for regions and transition regions (TR): plasmasphere, plasmapause TR, plasmasheet, plasmasheet TR ...

Global Effect of Long‐Lasting 07–12 October 2024 Geomagnetic Storms During the Transition From a Strong (G3) to a Severe (G4) on the Geomagnetic Field and Ionospheric Parameters Distribution

Space Weather, Volume 24, Issue 7, July 2026.
Abstract This study investigates the co‐evolution of geomagnetic field disturbances with ionospheric parameters and their characteristic latitudinal signatures by conducting a location and time‐dependent analysis of the 07–12 October 2024 events, to fill crucial gaps in understanding the coupled response of the magnetosphere‐ionosphere system. This has

Observing the Earth's Plasmasphere and Ionosphere From the Lunar Surface

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We present the analysis of the first lunar‐based observational characterization of the Earth's plasmasphere and ionosphere using Global Navigation Satellite Systems signals tracked from the lunar surface by the Lunar GNSS Receiver Experiment (LuGRE). The Earth‐Moon geometry enables limb sounding of the plasmasphere at altitudes exceeding 3,000
