A Semi‐empirical Framework for Dst Prediction Based on Global MHD Simulation of Earth's Magnetosphere

Space Weather, Volume 24, Issue 6, June 2026.
Abstract This study develops a semi‐empirical framework for Dst index forecasting by integrating the PPMLR‐MHD model of Earth's magnetosphere with four established empirical models (Burton, UCB, AK2, and Wang). The framework partitions the physics: global magnetopause and tail currents are simulated by MHD, while the ring current contribution is ...

Off-equatorial Electron Trajectories in Ganymede’s Magnetosphere: Implications for a Bifurcated Ring Current Under Different Jovian Wind Conditions

The Astrophysical Journal
Ganymede, Jupiter’s largest moon, hosts a minimagnetosphere sustained by its intrinsic magnetic field and embedded in the sub-Alfvénic Jovian plasma flow, providing a unique natural laboratory for studying energetic particle behavior. By combining a test-

Terrestrial Space Weather Protection Through Human‐Produced Mass‐Loading

Space Weather, Volume 24, Issue 6, June 2026.
Abstract While humans become more reliant on Earth's space environment, the potential for significant harm from severe space weather continues to grow. As structures from the sun reach Earth's magnetosphere and space environment, they deposit energy that fuels geomagnetic storms.

A Helicity-Based Method to Infer the CME Magnetic Field Magnitude in Sun and Geospace: Generalization and Extension to Sun-Like and M-Dwarf Stars and Implications for Exoplanet Habitability

, 2017
Patsourakos et al. (Astrophys. J. 817, 14, 2016) and Patsourakos and Georgoulis (Astron. Astrophys. 595, A121, 2016) introduced a method to infer the axial magnetic field in flux-rope coronal mass ejections (CMEs) in the solar corona and farther away in ...

Prediction Efficiency Skill Scores for Event Detection Analysis

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Prediction efficiency (PE) is a skill score that compares the data‐model metric of mean square error against the variance of the observations (i.e., using the average of the observed values as the “reference model” in the general skill score formula).

Mercury’s plasma environment after BepiColombo’s third flyby

Communications Physics
Understanding Mercury’s magnetosphere is crucial for advancing our comprehension of how the solar wind interacts with the planetary magnetospheres. Despite previous missions, several gaps remain in our knowledge of Mercury’s plasma environment.

High‐Latitude GPS Position Error During Substorms

Space Weather, Volume 24, Issue 6, June 2026.
Abstract Substorms produce rapid fluctuations in Global Navigation Satellite System (GNSS) signals, leading to degraded positioning performance at high latitudes. This study investigates the correlation of auroral structures on Global Positioning System (GPS) Precise Point Positioning (PPP) error during three substorm events with different strengths ...
