Importance of High Cadence Magnetometer Data for Investigating Geomagnetic Disturbances
Space Weather, Volume 24, Issue 6, June 2026.Abstract Geomagnetic disturbances (GMDs) are rapid changes in the magnetic field of the Earth that may drive geomagnetically induced currents (GICs), known to cause damage to infrastructure such as power grids and pipelines. Globally, GIC measurements are often hard to obtain; therefore, GMDs are used as a proxy for GICs.

Solar flares, coronal mass ejections and solar energetic particle event characteristics
, 2016 A new catalogue of 314 solar energetic particle (SEP) events extending over a large time span from 1984 to 2013 has been compiled. The properties as well as the associations of these SEP events with their parent solar sources have been thoroughly ...

Multi‐Wavelength Transformer‐Based 24‐Hour Solar Flare Forecasting at the Active‐Region Level
Space Weather, Volume 24, Issue 6, June 2026.Abstract Solar flare forecasting remains challenging due to the complex spatiotemporal evolution of solar active regions (ARs) and the severe class imbalance associated with high‐impact events. In this work, we investigate a transformer‐based framework for active‐region–level solar flare forecasting using short sequences of multi‐wavelength ...

Investigating Potential Benefits of Future Sub‐L1 Missions With STEREO‐A
Space Weather, Volume 24, Issue 6, June 2026.Abstract We present the first statistical study of geomagnetic storm forecasting using in situ data from the STEREO‐A spacecraft as a sub‐L1 monitor. Between November 2022 and June 2024, STEREO‐A crossed the Sun–Earth line, covering longitudinal and radial separations of ±15° $\pm 15{}^{\circ}$ from the Sun–Earth line and 0.01–0.06 au from Earth.

Regional and Seasonal Effects of Geomagnetic Storms on Terrestrial Weather
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract It has long been a mystery why small Total Solar Irradiation changes have significant effects on Earth's climate. Solar cycle correlation studies abound but cannot conclusively point to a viable physical mechanism. Here, I show that geomagnetic storms have a profound terrestrial weather impact.

LEO‐DOS Absorbed Dose Observations During the May 2024 Geomagnetic Superstorm
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract The Low‐Earth Orbit Space Radiation Dosimeter (LEO‐DOS) onboard Next‐Generation Satellite II (NEXTSat‐2) measured absorbed dose rate variations during the May 2024 geomagnetic superstorm. The observations show deep storm‐time penetration of solar energetic particle (SEP) spanning L ≈ 2–10, a pronounced enhancement near L ≈ 3 consistent with ...

Characteristics of coronal mass ejections in the near Sun interplanetary space [PDF]
Geofísica Internacional, 2004 Based on the observations from the Large Angle and Spectrometric Coronagraph (LASCO) on board the Solar and Heliospheric Observatory (SOHO) spacecraft we studied coronal mass ejections (CME) parameters between 6 and 10 solar radii from the Sun.
