TRACERS Small‐Scale Field‐Aligned Currents and Intense GPS Amplitude and Phase Scintillations in the Nightside Auroral Region

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We present conjugate observations of ionospheric small‐scale magnetic perturbations (dB) $(dB)$ and GPS scintillations from the Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) and the Canadian High Arctic Ionospheric Network (CHAIN) during a storm‐time substorm on 9 August 2025 in the nightside auroral region ...

Bursty magnetic reconnection at Saturn's magnetopause [PDF]

, 2013
[1] We infer the evolution of magnetopause reconnection from simultaneous in situ magnetopause crossings and auroral observations by Cassini on 19 July 2008.

Pre‐Existing Plasmaspheric Density Structure

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We perform a basic model experiment: we run two nearly identical plasmapause simulations, differing only by their initial conditions. The first run contains initial fine‐scale and mesoscale structure, and the second run is initialized with a featureless, circular plasmapause.

Space- and ground-based investigations of solar wind-magnetosphere-ionosphere coupling [PDF]

, 2006
This paper provides a brief review of the understanding of the coupled solar wind–magnetosphere–ionosphere system that can be attained from observations of the size of the ionospheric polar caps from space and the ground.

Control of the Jovian Magnetopause by Iogenic Plasma: Initial Results From Global MHD Simulations

Geophysical Research Letters
The size and variability of Jupiter's magnetosphere are not only determined by upstream conditions but also substantially influenced by internal processes within Jupiter's magnetosphere, specifically the dynamics of the rotation magnetodisc.

Statistical Evaluation of a Foreshock Transient Model Using Ground‐Based ULF Wave Observations

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Hot flow anomalies and foreshock bubbles are discontinuity–driven foreshock transients that generate significant geospace disturbances. A recently developed analytical model can predict their upstream perturbations. In this study, we further evaluate this model by comparing its predictions with geomagnetic disturbances measured by ground‐based

Explicit IMF By Dependence in Geomagnetic Activity: Modulation of Precipitating Electrons

Geophysical Research Letters, 2020
The most important driver of geomagnetic activity is the north–south ( Bz) component of the interplanetary magnetic field (IMF), which dominates the solar wind‐magnetosphere coupling and all solar wind coupling functions.

First Kinetic 3‐D Simulations of the High‐Latitude Electrojet Spanning an Entire Turbulent Flux Tube

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Radar and rocket observations of the terrestrial ionosphere frequently measure turbulent plasma waves, especially during geospace storms. The non‐linear behavior of these waves remains poorly characterized. This paper presents the first fully kinetic 3‐D particle‐in‐cell simulations of Farley–Buneman (FB) turbulence spanning an entire high ...

In situ observations of a solar wind compression-induced hot plasma injection in Saturn's tail [PDF]

, 2005
During the Saturn orbit insertion (SOI) fly-through of the Cassini spacecraft, Saturn's magnetosphere underwent a significant corotating interaction region (CIR) related compression.
