Can a Major Geomagnetic and Auroral Disturbance Originate From a Solar Active Region Close to the Limb?

Space Weather, Volume 23, Issue 8, August 2025.
Abstract When forecasting major geomagnetic storms, it is commonly assumed that coronal eruptions near the solar limb are not of concern. We here discuss two sequences of events: the Fátima storms of January 1938 and the Halloween storms of October/November 2003.

Hαspectroscopy and multiwavelength imaging of a solar flare caused by filament eruption [PDF]

Astronomy & Astrophysics, 2014
We study a sequence of eruptive events including filament eruption, a GOES C4.3 flare and a coronal mass ejection. We aim to identify the possible trigger(s) and precursor(s) of the filament destabilisation; investigate flare kernel characteristics; flare ribbons/kernels formation and evolution; study the interrelation of the filament-eruption/flare ...

Coronal Mass Ejections Deflected by Newly Emerging Flux: A Combined Analytic and Numerical Study

The Astrophysical Journal
Newly emerging flux (NEF) has been widely studied as a trigger of solar filament eruptions, but its influence on the subsequent dynamics remains poorly explored.

Comprehensive Study of Li Deposition and Solid Electrolyte Cracking by Integrating Simulation and Experimental Data

Advanced Science, Volume 12, Issue 25, July 3, 2025.
This study presents a phase‐field model integrating mechanical constraints, solid–solid contact, and large‐strain mechanochemical coupling to characterize lithium deposition and electrolyte cracking. Results show that reducing mechanical constraints, with good electrode–electrolyte contact, suppresses dendrite eruption in cracks and extends battery ...

Structure and Dynamics of Erupting Solar Prominences Using the Rolling Hough Transform: Toward a Feature-oriented Classification

The Astrophysical Journal
The classification of solar prominences has proven to be challenging, due to their diverse morphologies and dynamical behavior. Complexity is heightened when considering eruptive prominences, where the dynamics demand methods capable of capturing ...

Ensemble Model Using the Fokker–Planck Equation and Alfvénic Drift for Estimating Proton Flux in Solar Energetic Particle Events

Earth and Space Science, Volume 12, Issue 7, July 2025.
Abstract Observations of solar energetic particles (SEPs) accelerated at collisionless shocks driven by coronal mass ejections (CMEs) highlight the importance of understanding proton transport in velocity space. In this study, we present an ensemble model based on the one‐dimensional Fokker–Planck equation to estimate proton flux from CME‐driven shocks

Sigmoid Formation, Filament Destabilization, and Initiation of Weak Flare by Tether Cutting Reconnection

The Astrophysical Journal
We have studied a B-class solar flare and an associated filament eruption through multiwavelength observations. The flare is triggered at 16:24 UT on 2017 June 7 from Active Region(AR) 12661, and it maximizes at 16:54 UT.

Successive filament eruptions within one solar breakout event [PDF]

Proceedings of the International Astronomical Union, 2013
AbstractThe magnetic breakout model has been widely used to explain solar eruptive activities. Here, we apply it to explain successive filament eruptions occurred in a quadrupolar magnetic source region. Based on the high temporal and spatial resolution, multi-wavelengths observations taken by the Atmospheric Imaging Assembly (AIA) on board the Solar ...

Supra-arcade Downflows in an Extensive Fan Associated with a Giant Quiescent Solar Filament Eruption

The Astrophysical Journal
We investigate the aftermath of a giant quiescent solar filament eruption on 2023 December 24. One feature of the eruption is an extensive fan above the filament channel that is about 3 times as wide as similar structures that appear above active regions
