Simultaneous TRACERS and THEMIS Observations of Reversed Cusp Ion Dispersions and Dual‐Lobe Reconnection

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract We present observations from two consecutive TRACERS‐2 orbits through the northern low‐altitude cusp. During the first crossing, TRACERS‐2 observed reversed cusp ion dispersion and sunward convection, consistent with magnetopause reconnection tailward of the cusp during this northward IMF interval.

A Global Magnetic Topology Model for Magnetic Clouds. V

The Astrophysical Journal
Magnetic clouds (MCs) are large-scale magnetic structures in the solar wind whose internal physical processes remain only partially understood. In this work, we present an extended analytical model of MCs that simultaneously describes the magnetic field,

Electromagnetic Ion Cyclotron Waves in the Initial Phase of Geomagnetic Storms

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Using simultaneous magnetic field observations from 10 satellites and an automated detection algorithm, we identify broad regions of electromagnetic ion cyclotron (EMIC) wave activity during the initial phases of geomagnetic storms between September 2015 and October 2019.

Influence of Intermittency on the Energy Transfer Rate of Solar Wind Turbulence

The Astrophysical Journal Letters, 2023
The intermittency in the solar wind turbulence manifests itself in the anisotropic scaling due to the anisotropic spectral index and the intermittent level based on the extended P model. However, the influence of intermittency on the energy transfer rate

Is the Magnetic Field Line Curvature Really Important for Energetic Electron Losses From the Radiation Belt?

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Recently, Hua et al. (2026, https://doi.org/10.1029/2025GL120881) combined observations during a 4‐day storm period with numerical simulations and concluded that the abrupt electron loss in the field‐line‐curvature scattering (FLCS) region played a leading role in shaping the outer boundary of radiation belt (RB); the authors conjectured that ...

Magnetic field at geosynchronous orbit during high-speed stream-driven storms: Connections to the solar wind, the plasma sheet, and the outer electron radiation belt [PDF]

, 2010
Superposed-epoch analysis is performed on magnetic field measurements from five GOES spacecraft in geosynchronous orbit during 63 high-speed stream-driven storms in 1995–2005. The field strength and the field stretching angle are examined as functions of

MMS Observations of the Energetic Particles Within Kelvin‐Helmholtz Waves at the Boundary of the 10 May 2024 Coronal Mass Ejection (CME)

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract On 10 May 2024, Earth was hit by a CME that drove the largest geomagnetic storm in 20 years. Multi‐spacecraft observations previously showed that the ∼100 nT north‐south IMF bz ${b}_{z}$ variation was driven by Kelvin‐Helmholtz waves with wavelength ∼250 RE ${R}_{E}$ and reconnection jets in the ±z $\pm z$‐direction (Nykyri, 2024a, https://doi.
