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.

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 ...

Alfvénic Poynting Flux Characterized by a Substorm‐SMC Cycle and Ionospheric Influence

Space Weather, Volume 24, Issue 8, August 2026.
Abstract Geomagnetic substorms are fundamental processes of explosive geospace energy release within the Earth's magnetotail, which are usually divided into three phases: the growth phase, the expansion phase, and the recovery phase. Large‐scale electromagnetic energy transport during a geomagnetic substorm is in the form of Alfvén waves, transmitting ...

Orbital Decay of the Three SNIPE CubeSats During the Super Geomagnetic Storm in May 2024

Space Weather, Volume 24, Issue 8, August 2026.
Abstract The Mother's Day (Gannon) geomagnetic superstorm of May 2024 produced extreme thermospheric heating and expansion, resulting in enhanced atmospheric drag on low Earth orbiting (LEO) satellites. We investigate storm‐time thermospheric drag and density variability using three satellites of the Small‐scale magNetospheric and Ionospheric Plasma ...

ESA Swarm Satellites Plasma Density Products: Comparison and Validation Against Incoherent Scatter Radars Observations

Space Weather, Volume 24, Issue 8, August 2026.
Abstract The European Space Agency's Swarm mission has provided over a decade of continuous in situ measurements of the topside ionospheric plasma. With the release of various official plasma density products and the development of several calibration methods, selecting the most reliable data set has become an important issue for the scientific ...

Auroral Effect on Mid‐Latitude Ionospheric Disturbances Over Europe During the Extreme Geomagnetic Storm of 10 May 2024

Space Weather, Volume 24, Issue 8, August 2026.
Abstract Large ionospheric disturbances were observed over Europe during the extreme geomagnetic storm on 10 May 2024. This study analyzes GNSS‐derived total electron content (TEC) and all‐sky imager data to investigate these disturbances. Pronounced TEC enhancements, irregularities, and strong gradients were confined to the auroral region above the ...
