Intensification of the Electron Zebra Stripes in the Earth's Inner Magnetosphere During Geomagnetic Storms

Geophysical Research Letters
We examined rapid variations in the electron zebra stripe patterns, specifically at L = 1.5, over a three‐month duration, using twin Van Allen Probes within Earth's inner magnetosphere. During geomagnetically quiet intervals, these stripes exhibit a peak‐

Model‐Data Comparison of Electron Energization Associated With Kinetic Alfvén Waves in the Near Earth Magnetotail

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract A model‐data comparison between Gyrofluid‐Kinetic Electron simulations and MMS satellite observations of kinetic Alfvén waves (KAW) and associated electron energization in the near Earth magnetotail is presented. The observations reveal 10 keV electron beams embedded within intense KAW field‐aligned currents.

Magnetic signatures of plasma-depleted flux tubes in the Saturnian inner magnetosphere [PDF]

, 2007
Initial Cassini observations have revealed evidence for interchanging magnetic flux tubes in the inner Saturnian magnetosphere. Some of the reported flux tubes differ remarkably by their magnetic signatures, having a depressed or enhanced magnetic ...

Observational features of charge distribution in Earth’s inner magnetosphere

Communications Physics
Understanding the motion of charged particles in the electromagnetic field in the inner magnetosphere is essential for space science and space weather. Charge accumulation can occur due to the dipole magnetic and convective electric fields in this region.

PROSWIN: Probabilistic Solar Wind Speed Forecasting Using Deep Distributional Regression From Solar Images

AGU Advances, Volume 7, Issue 8, November 2026.
Abstract Accurately predicting fast solar wind conditions is challenging, as uncertainties are large and unquantified by traditional single‐value prediction models. In particular, the risks of high‐speed solar wind streams (HSSs), which can cause damage to technological infrastructure, cannot be reliably assessed without probabilistic forecasts.

Modeling of the Jovian Magnetosphere [PDF]

Annales Geophysicae, 2005
This paper presents a global model of the Jovian magnetosphere which is valid not only in the equatorial plane and near the planet, as most of the existing models are, but also at high latitudes and in the outer regions of the magnetosphere. The model

The Spatial Localization of Storm‐Time ULF Waves Due To Plasmaspheric Plumes

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract The generation and propagation of Ultra Low Frequency (ULF) waves are intrinsically coupled to the cold plasma population in the terrestrial magnetosphere. During geomagnetic storms, extreme reconfigurations of the cold plasma create a complex and dynamic system that drastically modifies this coupling.

Van Allen Probes Observations of a Fundamental Poloidal Wave in the Plasmasphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract All past spacecraft observations of fundamental poloidal Alfvén (P1) waves attributed to ion drift resonance have been made outside the plasmasphere. In this study, we present the first spacecraft observations of a plasmaspheric P1 wave driven by that resonance.

Excitation of Alfvén waves by modulated HF heating of the ionosphere, with application to FAST observations [PDF]

Annales Geophysicae, 2002
During the operation of the EISCAT high power facility (heater) at Tromsø, Norway, on 8 October 1998, the FAST spacecraft made electric field and particle observations in the inner magnetosphere at 0.39 Earth radii above the heated ionospheric ...
