Electromagnetic Ion Cyclotron Waves in a Magnetic Reconnection Exhaust at Earth's Magnetopause
Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Plasma waves can initiate, regulate, or reflect magnetic reconnection efficiently converting magnetic energy into plasma energy. While waves ranging from below the ion cyclotron frequency to above the electron plasma frequency are commonly observed near reconnection sites, electromagnetic ion cyclotron (EMIC) waves—frequent in other plasma ...

The Substorms of 26 February 2008: A Data‐Mining Perspective
Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Reconstruction of the magnetospheric magnetic field using swarms of virtual spacecraft provided by data mining confirms seminal in situ evidence (Angelopoulos et al., 2008, https://doi.org/10.1126/science.1160495) that on 26 February 2008 an X‐line emerged in the region between two distant Time History of Events and Macroscale Interactions ...

Observation of a Knotted Electron Diffusion Region in Earth's Magnetotail Reconnection
Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Magnetic reconnection is a fundamental plasma process that alters the magnetic field topology and releases magnetic energy. Most numerical simulations and spacecraft observations assume a two‐dimensional diffusion region, with the electron diffusion region (EDR) embedded in the same plane as the ion diffusion region (IDR) and a uniform guide ...

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Geomagnetically Induced Currents (GICs) are a hazard to power systems. In this letter, we present a case study to understand why a Sudden‐Commencement‐associated 20A GIC spike, measured at mid‐latitude in Virginia, US, increased to 30A within 2 min of interplanetary shock arrival.

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.Abstract A map is presented of median 1‐min‐resolution peak geoelectric‐field strength across the United States as would be induced by magnetic storms as intense as the 2 September 1859 Carrington storm. The map is constructed from two data sets: Magnetometer time series from 22 ground‐based observatories recording 40 magnetic storms, and surface ...

Three‐Dimensional Anisotropy of Turbulence at Ion‐Scales in the Magnetotail's Bursty Bulk Flow
Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.Abstract Using the data from Magnetospheric Multiscale mission, we statistically investigate the anisotropy of turbulence within bursty bulk flows (BBFs) in the Earth's magnetotail. By computing five‐point second‐order structure functions, we reveal the three‐dimensional anisotropy and scaling properties of turbulence at ion scales.
