Local Generation of Plasmaspheric Plume Hiss

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The statistical analysis of hiss waves observed in the plasmaspheric plume (Wu et al., 2026, https://doi.org/10.1029/2026gl121667) is significant for identifying nonlinear wave growth processes in the equatorial region. Because nonlinear growth rates greatly exceed linear growth rates, they enable the local generation of new wave packets in ...

Quasi‐Homologous Solar Flares and Impacts on Thermospheric Density and Satellite Orbital Drag

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Quasi‐Homologous Flaring (QHF) activity from active regions on the Sun releases intense electromagnetic radiation in recurrent bursts over extended periods. In this letter, we present the effects of recurrent impulsive extreme ultraviolet (EUV) heating on thermospheric neutral density and the resulting atmospheric drag on satellites based on ...

Local Acceleration of Multi‐MeV Electrons Inside Earth's Impenetrable Barrier During the May 2024 Superstorm

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The inner radiation belt (L* < 3) has long been considered an impenetrable barrier to ultra‐relativistic electrons. Here we show that this barrier can be breached under extreme space weather conditions. Using continuous near‐equatorial observations from the Arase satellite, we show that the May 2024 superstorm rapidly generated multi‐MeV ...

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.

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.

Quantifying Non‐Maxwellian Properties of Ion Populations During Reconnection at Earth's Magnetopause

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract We investigate ion velocity‐space features within the exhaust of magnetopause reconnection using a global hybrid‐Vlasov simulation. The Hermite transform and Gaussian Mixture Model (GMM) are applied to quantify the complexity of velocity‐space structures that arise during the mixing of magnetospheric and magnetosheath ion populations.

Cosmogenic 10Be as a Tracer for Recent Heliospheric Encounters With Interstellar Cold Clouds and Nearby Supernovae

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Recent works suggest there are periods when the Sun encountered massive interstellar cold clouds which compressed the heliosphere to within Earth's orbit, exposing Earth to interstellar galactic cosmic rays and energetic particles of heliospheric origin.

The Evolution of Parallel Electric Field Across the Earth's Magnetosheath

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract In Earth's collisionless magnetosheath, turbulence evolution and energy transformation across the system, especially at kinetic scales, remain poorly quantified without full‐coverage of high‐resolution observations. Using multi‐traversal observations from the 2023 and 2024 Magnetospheric Multiscale (MMS) Unbiased Magnetosheath Campaign, we ...

Mini-magnetospheres and Moon-magnetosphere interactions: Overview Moon-magnetosphere Interactions

, 2019
"Moon-magnetosphere interaction" stands for the interaction of magnetospheric plasma with an orbiting moon. Observations and modeling of moon-magnetosphere interaction is a highly interesting area of space physics because it helps to better understand the basic physics of plasma flows in the universe and it provides geophysical information about the ...

Drift‐Resonance Driven by Field Line Resonance Gradients: A Mechanism for Non‐Dispersive Microinjection Events

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Ultra‐low‐frequency waves in the magnetosphere often produce field line resonances with strong spatial gradients in wave amplitude. We analyze a form of drift resonance driven by these gradients near the resonant field line. This mechanism differs fundamentally from conventional gradient‐ and curvature‐driven drift resonance and predicts an ...
