On the North‐South Symmetry of the Chorus Source Region: Conjugate Observations by the Cluster Spacecraft

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Chorus waves are arguably the most important electromagnetic emissions in the Earth's magnetosphere, being responsible for both energization and loss of radiation belt electrons. Chorus generation, inherently related to nonlinear wave‐particle interactions, as well as the frequency‐time shapes of individual elements forming it, are not yet ...

Localized Threats: How Ground Conductivity Shapes the Geoelectric Response

Space Weather
Geomagnetic storms can induce strong geoelectric fields in the ground. These fields drive geomagnetically induced currents in technological conductor systems, such as power grids.

GOES‐R Series X‐Ray Sensor (XRS): 2. On‐Orbit Measurements and Calibrations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract An X‐Ray Sensor (XRS) has been onboard each of the National Oceanic and Atmospheric Administration (NOAA) Geostationary Operational Environmental Satellites (GOES) since 1975. XRS measures full‐disk soft X‐ray irradiance in two wavelength bands, 0.05–0.4 nm and 0.1–0.8 nm.

Comparison of ICON/MIGHTI and TIMED/SABER Neutral Temperature Measurements at Conjunctions in the Lower Thermosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract This study presents a cross‐comparison of mesosphere and lower thermosphere (MLT) neutral temperatures between 88 and 110 km measured by ICON/Michelson Interferometer for Global High‐resolution Thermospheric Imaging (MIGHTI) and Thermosphere Ionosphere Mesosphere Energetics and Dynamics/Sounding of the Atmosphere using Broadband Emission ...

Solar Wind‐Magnetosphere‐Ionosphere Coupling During the October 2024 Storms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Two geomagnetic storms occurred in October 2024 (Oct 6‐9 and 10–12), driven by the impact of a series of interplanetary coronal mass ejections on the magnetosphere. The first was a moderate storm, with peak Sym‐H near −150 nT, whereas the second was intense, Sym‐H reaching −340 nT.

Multi‐Decadal Trends in the Low Latitude foF2 Driven by Secular Magnetic Variations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Long‐term ionospheric trends have been widely studied, but their origin and magnitude remain subjects of debate. This study quantifies the linear trend in the F2‐region critical frequency (foF2) and its local time dependence using observations from eight low‐latitude ionosonde stations.

Validation of VERB‐3D Simulation Results in Response to the COSPAR ISWAT Challenge

Space Weather, Volume 24, Issue 5, May 2026.
Abstract In response to the first long‐term simulation challenge issued by the COSPAR International Space Weather Action Team (ISWAT) G3‐04 team (“Internal Charging Effects and the Relevant Space Environment”), we evaluate the performance of the Versatile Electron Radiation Belt‐3D model by simulating the radiation belt electron dynamics for the entire
