Predicting Geomagnetic Activity in the Ascending and Declining Phases of the Solar Cycle

Space Weather, Volume 24, Issue 8, August 2026.
Abstract Most predictions of space climate, that is, the long‐term behavior of the solar‐terrestrial environment, have focused on forecasting the 11‐year sunspot cycle. Geomagnetic activity, on the other hand, has mainly been predicted in shorter, space weather timescales of up to days to weeks.

AI Challenge for Satellite Tracking and Orbit Resilience Modeling (STORM‐AI): Data Set, Design, and Results

Space Weather, Volume 24, Issue 8, August 2026.
Abstract Precise thermospheric density forecasting is critical for mitigating satellite drag in Low Earth Orbit (LEO), but traditional empirical models such as MSIS and JB2008 can fail during geomagnetic storms. To evaluate whether AI can better capture this transient behavior, the 2025 MIT ARCLab Prize for AI Innovation in Space asked participants to ...

Quantifying the evolution of interplanetary coronal mass ejections by coupling physics-based and data-driven modeling

, 2022
Coronal mass ejections (CMEs) are considered to be one of the main drivers of space weather. They consist of large-scale eruptions of magnetised plasma, originating predominantly from active regions in the low solar corona and are extremely common events. During solar maxima, they occur on a daily basis, at times exceeding 10 events per day.

Real‐Time Prediction of Two Geomagnetic Storms Using Solar Orbiter as a Far Upstream Solar Wind Monitor

Space Weather, Volume 24, Issue 8, August 2026.
Abstract We present the first real‐time predictions of coronal mass ejection (CME) magnetic structure and resulting geomagnetic impact at Earth for two events using far‐upstream observations from Solar Orbiter during March 2024. While our approach assumes idealized conditions for CME propagation and scaling, in situ magnetic field data from upstream ...

Predicting Coronal Mass Ejection Travel Times Using Enhanced Model‐Guided Machine Learning

Space Weather, Volume 24, Issue 8, August 2026.
Abstract Coronal mass ejections (CMEs) are key drivers of space weather events, posing risks to both space‐borne and ground‐based systems. An accurate prediction of their arrival time at Earth is critical for impact mitigation. To this end, physics‐informed artificial intelligence (AI) approaches have proven more effective than purely data‐driven or ...
