Simulated Operational Testing of the Prototype Implementation of the SOFIE Model: The 2025 Space Weather Prediction Testbed Exercise

Space Weather, Volume 24, Issue 3, March 2026.
Abstract The CLEAR Space Weather Center of Excellence's solar energetic particle (SEP) model, SOlar wind with FIeld lines and Energetic particles (SOFIE), was run and evaluated on‐site during the Space Weather Prediction Testbed (SWPT) exercise at the National Oceanic and Atmospheric Administration's Space Weather Prediction Center (NOAA/SWPC) in May ...

Pinching of ICME Flux Rope: Unprecedented Multipoint Observations of Internal Magnetic Reconnection during Gannon’s Superstorm

The Astrophysical Journal Letters
The extreme solar storm of 2024 May 10, during the 25th solar cycle, which recorded a symmetric H component index (Sym-H) reaching −500 nT, was the strongest since the 2003 Halloween storm.

Differences in Ultra‐Low‐Frequency Waves Associated With Dipolarization in the Near‐Earth Magnetotail Between Substorms and Pseudosubstorms

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract We studied the characteristics of ultra‐low‐frequency (ULF) waves associated with dipolarization in the near‐Earth plasma sheet for substorms and pseudosubstorms, employing superposed epoch analysis of data from the Time History of Events and Macroscale Interactions during Substorms (THEMIS) spacecraft.

Alfvén Waves from Interchange Reconnection at Separators as a Possible Source of Switchbacks

The Astrophysical Journal
Parker Solar Probe has observed Alfvénic fluctuations of amplitude large enough to occasionally reverse the local magnetic field direction—a phenomenon known as a switchback. Some have attributed switchbacks to reconnection in the low corona between open

Key issues on magnetic reconnection at Mercury

Earth and Planetary Physics
Magnetic reconnection processes and their impact on planetary magnetospheric dynamics exhibit significant differences due to differences in upstream solar wind conditions and internal planetary environments.

Solar‐Wind Triggering of Substorm Onset During the May 2024 Superstorm: Coordinated Global Observations and Simulations

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Substorms are often described by a loading‐unloading cycle, where onset follows gradual accumulation of solar wind magnetic flux in the magnetosphere. Yet observations indicate that intense substorms can also be directly driven, though the underlying mechanism remains unresolved.

Spectral Properties and Energy Injection in Mercury's Magnetotail Current Sheet

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Mercury's magnetotail hosts a thin and highly dynamic current sheet (CS), where magnetic reconnection and strong fluctuations frequently occur. Here, we statistically analyze magnetic field power spectra across 370 magnetotail CSs observed by MESSENGER.

Searching for Electron‐Only Magnetic Reconnection on Lunar Crustal Magnetic Fields: A Case Study of Kaguya Low‐Altitude Observations

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Due to the lack of low‐altitude (<∼ ${< } \sim $50 km), high‐time‐resolution measurements, expected electron‐only magnetic reconnection near lunar magnetic anomalies (LMAs) has not been directly observed by lunar orbiters even though it is expected from numerical simulations and laboratory experiments.

Current sheet formation and magnetic reconnection in solar magnetic fields

, 2013
Diese Arbeit beschreibt magnetische Rekonnexion an dünnen Stromschichten in Konfigurationen ohne verschwindendes Magnetfeld. Dabei wird eine Methode entwickelt, die die Bestimmung der Rekonnexionsrate ohne die Einbeziehung eines parallelen elektrischen Feldes ermöglicht. Zusätzlich werden grundsätzliche geometrische Unterschiede zwischen Rekonnexion in
