Integration of solar flare and coronal mass ejection event dataHarvard Dataverse [PDF]

open access: yesData in Brief
Solar flares and coronal mass ejections are solar transient events that can impact our technological infrastructure in near-Earth and Earth environments. While related, not all flares generate CMEs and there are a limited number of resources that connect

Effect of an Interplanetary Coronal Mass Ejection on Saturn’s Radio Emission

open access: yesFrontiers in Astronomy and Space Sciences, 2022
The Saturn Kilometric Radiation (SKR) was observed for the first time during the flyby of Saturn by the Voyager spacecraft in 1980. These radio emissions, in the range of a few kHz to 1 MHz, are emitted by electrons travelling around auroral magnetic ...

Coronal dimming and the coronal mass ejection onset [PDF]

open access: yesAstronomy and Astrophysics, 2003
A set of five observations of extreme-ultraviolet (EUV) coronal dimming associated with coronal mass ejection (CME) activity is examined. Using spectroscopic data, plasma characteristics across a broad range of temperatures from 20 000 K to 2 million K are determined. The dimming events are found to coincide in time, and to coincide spatially, with the

Stellar coronal mass ejections

open access: yesSerbian Astronomical Journal, 2022
Stellar coronal mass ejections (CMEs) are a growing research field, especially during the past decade. The large number of so far detected exoplanets raises the open question for the CME activity of stars, as CMEs may strongly affect exoplanetary atmospheres.

COMPOSITION OF CORONAL MASS EJECTIONS [PDF]

open access: yesThe Astrophysical Journal, 2016
ABSTRACT We analyze the physical origin of plasmas that are ejected from the solar corona. To address this issue, we perform a comprehensive analysis of the elemental composition of interplanetary coronal mass ejections (ICMEs) using recently released elemental composition data for Fe, Mg, Si, S, C, N, Ne, and He as compared to O and H ...

Reconnection in a slow Coronal Mass Ejection [PDF]

open access: yesAnnales Geophysicae, 2008
This paper aims at studying reconnection occurring in the aftermath of the 28 May 2004, CME, first imaged by the LASCO (Large Angle and Spectrometric Coronagraph) C2 at 11:06 UT. The CME was observed in White Light and UV radiation: images acquired by

Nanodust dynamics during a coronal mass ejection [PDF]

open access: yesAnnales Geophysicae, 2017
The dynamics of nanometer-sized grains (nanodust) is strongly affected by electromagnetic forces. High-velocity nanodust was proposed as an explanation for the voltage bursts observed by STEREO.

The evolution of our understanding of coronal mass ejections

open access: yesFrontiers in Astronomy and Space Sciences, 2023
The unexpected observation of a sudden expulsion of mass through the solar corona in 1971 opened up a new field of interest in solar and stellar physics.

Effect of Latitude of Sunspots on Earth-Intersecting Trajectory of Plasma [PDF]

open access: yesIranian Journal of Astronomy and Astrophysics, 2020
Solar flares and Coronal Mass Ejections form around the edges of sunspots. If the plasma from such events is incident on the Earth’s magnetosphere, significant disruptions to electrical systems can occur. However, sunspots occur around the surface of the
