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 ...

Coronal Mass Ejection–Associated Coronal Dimmings

The Astrophysical Journal, 2008
We report on a statistical analysis of 96 CME-associated EUV coronal dimmings between 1998 and 2000. We investigate the size and location of the events and characterize how these events evolve with time. The durations typically range from 3 to 12 hr. The dimmings appear most frequently within the belt of active regions (20°-50° latitude).

Ground‐Based Solar Radio Observations From the Mexican e‐Callisto Stations During the May 2024 Extreme Space Weather Events

Space Weather, Volume 24, Issue 8, August 2026.
Abstract The period from 1 to 14 May 2024 was marked by some of the most intense solar activity of Solar Cycle 25, including multiple X‐class flares, fast coronal mass ejections (CMEs), and diverse solar radio emissions. We present observations from the Mexican e‐Callisto network (REC‐Mx), including long‐duration continuum emissions (CTMs), Type II ...

Coronal Mass Ejections: Models and Their Observational Basis

Living Reviews in Solar Physics, 2011
Coronal mass ejections (CMEs) are the largest-scale eruptive phenomenon in the solar system, expanding from active region-sized nonpotential magnetic structure to a much larger size.

A Deep Learning Method for Automatic Coronal Mass Ejection Feature Identification

The Astrophysical Journal Supplement Series
Coronal mass ejections (CMEs), intense solar eruptive phenomena, are the primary drivers of extreme space weather storms on Earth. As space activities become increasingly frequent and infrastructure more reliant on space-based systems, the rapid and ...

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 ...

Distorted Magnetic Flux Ropes within Interplanetary Coronal Mass Ejections

The Astrophysical Journal
Magnetic flux ropes (MFRs) at the center of interplanetary coronal mass ejections (ICMEs) are often characterized as simplistic cylindrical or toroidal tubes with field lines that twist around the cylinder or torus axis.

Variability of dB/dt in the African Sector During Solar Cycle 24—Implications for Geomagnetically Induced Currents

Space Weather, Volume 24, Issue 8, August 2026.
Abstract This paper quantitatively characterizes dB/dt peaks at four African equatorial‐ and low‐latitude stations, along latitudinal and local‐time gradients across different phases of selected geomagnetic storms. We investigate dB/dt response for intense geomagnetic storms, Dst ≤ −100 nT observed during solar cycle 24 over four stations in the ...
