Segmentation and Tracking of Eruptive Solar Phenomena With Convolutional Neural Networks
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.Abstract Solar eruptive events are complex phenomena, which most often include coronal mass ejections (CME), CME‐driven compressive and shock waves, flares, and filament eruptions. CMEs are large eruptions of magnetized plasma from the Sun's outer atmosphere or corona, that propagate outward into the interplanetary space.

Particle acceleration in solar flares [PDF]
The most direct signatures of particle acceleration in flares are energetic particles detected in interplanetary space and in the Earth atmosphere, and gamma rays, neutrons, hard X-rays, and radio emissions produced by the energetic particles in the ...

High‐Latitude Electrodynamics and Thermospheric Density Variations During the 2024 Gannon Storm
Space Weather, Volume 24, Issue 2, February 2026.Abstract This study investigates high‐latitude electrodynamics and thermospheric density variations during the 2024 Gannon's storm. First, the auroral precipitation module of Auroral Spectra and High‐Latitude Electric field variabilitY, ASHLEY‐A, is improved to more accurately capture the location of auroral precipitation observed during this ...

Space Weather, Volume 24, Issue 2, February 2026.Abstract On 10 May 2024, a severe G5 geomagnetic storm—the most intense of solar cycle 25—significantly disturbed the global ionosphere. This study presents a comprehensive analysis using multi‐instrument observations, including ground‐based measurements from BDS‐GEO total electron content (TEC), digital ionosondes, and magnetometers; model outputs ...

First analysis of GLE 72 event on 10 September 2017: Spectral and anisotropy characteristics
, 2018 Using neutron monitor and space-borne data we performed an analysis of the second ground level enhancement of solar cycle 24, namely the event of 10 September 2017 (GLE 72) and derive the spectral and angular characteristics of GLE particles.
