Self‐Limiting of Artificial Electron Radiation Belts: Evidence From the Starfish Prime High‐Altitude Nuclear Explosion

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The 1962 Starfish Prime high‐altitude 1.4‐megaton nuclear detonation injected large amounts of fission‐produced energetic electrons into the inner magnetosphere (L = 1.12), creating an intense artificial radiation belt that persisted for years. In this study, we revisit historical data from this unprecedented event to investigate the potential

Improving Geomagnetic Perturbation Forecasts in the Southern Hemisphere via Kernel‐Based Encoding of Mirror Symmetry

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Accurate forecasting of geomagnetic perturbations is essential for assessing space weather risk of geomagnetic activities. Thanks to decades of magnetometer observations from world‐wide distributed networks and upstream solar wind observations at L1, data‐driven modeling of global geomagnetic perturbations has become increasingly feasible ...

Radio‐Quiet Ionosonde Observations for Monitoring Absorption in the HF Band

Radio Science, Volume 61, Issue 8, August 2026.
Abstract This work presents a technique to monitor ionospheric absorption in the HF radio band using ionosondes. For this purpose, the ionosondes were run in a radio‐silent mode, recording not reflections of their own emitted signals but oblique signals from transmitters of opportunity.

Quantitative Assessment of Geographic Control of December Solstice EIA Crest Shifts Over Southeast Asia Under Low Solar Activity

Space Weather, Volume 24, Issue 8, August 2026.
Abstract This study quantitatively assesses the drivers of the Equatorial Ionization Anomaly (EIA) morphology and latitudinal shifts over Southeast Asia during the December solstice. We use a 27‐year ionospheric data set (1998–2024) of total electron content (TEC) and F2‐layer peak electron density (NmF2) under geomagnetically quiet conditions.
