Relating near-Earth observations of an interplanetary coronal mass ejection to the conditions at its site of origin in the solar corona [PDF]

, 2005
A halo coronal mass ejection (CME) was detected on January 20, 2004. We use solar remote sensing data (SOHO, Culgoora) and near-Earth in situ data (Cluster) to identify the CME source event and show that it was a long duration flare in which a magnetic ...

First Taste of Hot Channel in Interplanetary Space

, 2015
Hot channel (HC) is a high temperature ($\sim$10 MK) structure in the inner corona revealed first by Atmospheric Imaging Assembly (AIA) on board \textit{Solar Dynamics Observatory}. Eruption of HC is often associated with flare and coronal mass ejection.

Electron Structures in Titan's Induced Magnetosphere and Low‐Frequency Wave Activity

Journal of Geophysical Research: Planets, Volume 130, Issue 6, June 2025.
Abstract The interaction of Titan's ionosphere with Saturn's magnetosphere leads to a mix of perturbed electromagnetic fields and accelerated and thermalized plasma in the induced magnetosphere. The complexity of this region has been noted in previous studies.

Partially Erupted Prominence Material as a Diagnostic of Coronal Mass Ejection Trajectory

Space Weather, 2023
Coronal mass ejections (CMEs) are energetic releases of large‐scale magnetic structures from the Sun. CMEs can have impacts on spacecraft and at Earth. This trajectory is typically assumed to be radial, but often the CME moves outward with some spatial ...

Multipoint radio probe of the solar corona: The trans-coronal radio array fleet

Frontiers in Astronomy and Space Sciences, 2022
The Trans-Coronal Radio Array Fleet (T-CRAF) is a mission concept designed to continuously probe the magnetic field and plasma density structure of the corona at heliocentric distances of ≈ 2 − 10 R⊙ (solar radius, R⊙ = 695, 700 km).

THE HEIGHT EVOLUTION OF THE “TRUE” CORONAL MASS EJECTION MASS DERIVED FROM STEREO COR1 AND COR2 OBSERVATIONS [PDF]

, 2013
Using combined STEREO-A and STEREO-B EUVI, COR1, and COR2 data, we derive deprojected coronal mass ejection (CME) kinematics and CME “true” mass evolutions for a sample of 25 events that occurred during 2007 December to 2011 April.

Ionospheric Analysis With Martian Mutual Radio Occultation

Journal of Geophysical Research: Planets, Volume 130, Issue 6, June 2025.
Abstract This study presents a comprehensive analysis of the Martian ionosphere using Mutual Radio Occultation (RO) observations between Mars Express and Trace Gas Orbiter, featuring 71 full vertical profiles out of a total of 124 measurements. Among these, 35 measurements were taken from regions with Solar Zenith Angles lower than 40°.

Hemispheric Distribution of Halo Coronal Mass Ejection Source Locations

The Astrophysical Journal
The hemispheric asymmetry of solar activity is one of the essential physical consequences of the interior dynamo process. However, the hemispheric distribution of halo coronal mass ejection (HCME) source locations has not been investigated in detail ...

V arc interplanetary coronal mass ejections observed with the Solar Mass Ejection Imager

, 2007
[1] Since February 2003, the Solar Mass Ejection Imager (SMEI) has been observing interplanetary coronal mass ejections (ICMEs) at solar elongation angles e > 20°.

The onset of coronal mass ejections

The Astrophysical Journal, 1985
A study has been made of the nonlinear magnetostatic equilibria available to an axisymmetric corona as excess mass is added to a region confined in latitudinal extent at the coronal base. It is found that sequences of equilibrium solutions evolve discontinuously in response to increasing gas pressure, in contrast to the continuous evolution that occurs
