Deep Learning‐Based Prediction of High‐Speed Solar Wind Streams: Spatio‐Temporal Dependencies in Coronal Hole Dynamics

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract High‐speed solar wind streams (HSS), originating from coronal holes (CH), are key drivers of space weather disturbances and heliospheric dynamics. However, forecasting HSS remains challenging due to the evolving morphology of CH. In this study, we present a deep learning‐based framework that models the spatiotemporal relationship between CH ...

Testing the Empirical Shock Arrival Model using Quadrature Observations

, 2013
The empirical shock arrival (ESA) model was developed based on quadrature data from Helios (in-situ) and P-78 (remote-sensing) to predict the Sun-Earth travel time of coronal mass ejections (CMEs) [Gopalswamy et al. 2005a].

Enhanced Radiation Exposure of Airline Crew and Passengers During the May 2024 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Enhanced radiation at aviation altitudes is a concern for flight crew and passengers. During space weather events, solar flares and coronal mass ejection (CME) driven shocks are sources of energetic particles that can reach Earth's near‐space environment and interact with its magnetic field and atmosphere.

Debye‐Scale Bipolar Structures and Their Role in the Electron Trajectory Instability at the Bow Shock

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract A number of mechanisms have been suggested to operate within the terrestrial bow shock to redistribute energy contained in the incoming solar wind flow. The majority of mechanisms involve the generation of turbulence while some are based on particle motion alone.

Using an Ellipsoid Model to Track and Predict the Evolution and Propagation of Coronal Mass Ejections

, 2012
We present a method for tracking and predicting the propagation and evolution of coronal mass ejections (CMEs) using the imagers on the STEREO and SOHO satellites.

Lateral Confinement and the Remarkably Self-similar Nature of Coronal Pseudostreamer Mass Ejections

The Astrophysical Journal, 2023
Coronal mass ejections (CMEs) that originate from pseudostreamers, which separate coronal holes of the same magnetic polarity, are characterized by a narrow (∼5°–30°), fan-shaped appearance in white-light coronagraph images.

Longitudinal Variability of Pre‐Midnight Equatorial Plasma Bubbles Under Disturbed Geomagnetic Conditions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Equatorial plasma bubbles (EPBs) pose significant challenges to trans‐ionospheric radio communication and navigation systems. Because of their disruptive effects, evaluating and predicting them is key for the development of space systems. The influence of geomagnetic activity on EPBs remains unclear, partly due to limited low‐latitude neutral ...

The Gannon Storm's Impact on Electric and Magnetic Fields in Italy: A Regional Perspective

Space Weather, Volume 24, Issue 1, January 2026.
Abstract The intense May 2024 geomagnetic storm provided an opportunity to conduct the first analysis of geoelectric hazards in Italy. Data from three geomagnetic observatories and a magnetotelluric station were analyzed to examine the spatiotemporal evolution of storm‐induced variations.

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 ...
