A study of a coronal hole associated with a large filament eruption
(2017)
We report the results of a detailed study of an equatorial coronal hole and a dimming region related to the eruptions of a nearby large filament and subsequent coronal mass ejections (CMEs). The dynamic eruptions of the ...
Large non-radial propagation of a coronal mass ejection on 2011 January 24
(Elsevier, 2020-03)
Understanding the deflection of coronal mass ejections (CMEs) is of great interest to the space weather community because of their implications for improving the prediction of CME. This paper aims to shed light into the ...
Editorial: Earth-affecting Solar Transients
(Springer, 2018-05)
This Topical Collection (TC) is devoted to the recent advancement in the study of Earth-affecting solar transients. Earth-affecting solar transients encompass a broad range of phenomena, including major solar flares, coronal ...
Coronal Mass Ejections from the Same Active Region Cluster: Two Different Perspectives
(Springer, 2015-06)
The cluster formed by active regions (ARs) NOAA 11121 and 11123, approximately located on the solar central meridian on 11 November 2010, is of great scientific interest. This complex was the site of violent flux emergence ...
Determining the Solar Source of a Magnetic Cloud Using a Velocity Difference Technique
(Springer, 2011-01)
For large eruptions on the Sun, it is often a problem that the core dimming region cannot be observed due to the bright emission from the flare itself. However, spectroscopic data can provide the missing information through ...
Estimating the mass of CMEs from the analysis of EUV dimmings
(EDP Sciences, 2019-07)
Context. Reliable estimates of the mass of coronal mass ejections (CMEs) are required to quantify their energy and predict how they affect space weather. When a CME propagates near the observer's line of sight, these tasks ...
The Recovery of CME-Related Dimmings and the ICME's Enduring Magnetic Connection to the Sun
(Springer, 2008-11)
It is generally accepted that transient coronal holes (TCHs, dimmings) correspond to the magnetic footpoints of CMEs that remain rooted in the Sun as the CME expands out into the interplanetary space. However, the observation ...
Simulations of the Kelvin-Helmholtz instability driven by coronal mass ejections in the turbulent corona
(IOP Publishing, 2016-02)
Recent high-resolution Atmospheric Imaging Assembly/Solar Dynamics Observatory images show evidence of the development of the Kelvin–Helmholtz (KH) instability, as coronal mass ejections (CMEs) expand in the ambient corona. ...
Why are CMEs large-scale coronal events: nature or nurture?
(Copernicus Publications, 2008-12)
The apparent contradiction between small-scale source regions of, and large-scale coronal response to, coronal mass ejections (CMEs) has been a long-standing puzzle. For some, CMEs are considered to be inherently large-scale ...
Configuración magnética pre-eruptiva de la región NOAA 12127 mediante extrapolación no lineal del campo
(Asociación Argentina de Astronomía, 2021)
Estudiamos las propiedades magnéticas de la región activa NOAA 12127 previas a una fulguración clase M1.5, acompañada de una eyección coronal de masa, el 1 de agosto de 2014. Estimamos su campo magnético coronal preeruptivo ...
