Automated detection of solar eruptions

Journal of Space Weather and Space Climate, 2015
Observation of the solar atmosphere reveals a wide range of motions, from small scale jets and spicules to global-scale coronal mass ejections (CMEs).

Characteristics of coronal mass ejections in the near Sun interplanetary space [PDF]

Geofísica Internacional, 2004
Based on the observations from the Large Angle and Spectrometric Coronagraph (LASCO) on board the Solar and Heliospheric Observatory (SOHO) spacecraft we studied coronal mass ejections (CME) parameters between 6 and 10 solar radii from the Sun.

Observing Solar Coronal Mass Ejections from Space [PDF]

In this contribution to the panel discussion of the IAU Symposium 388 Solar and Stellar Coronal Mass Ejections , I concentrate on white-light observations of solar coronal mass ejections (CMEs) from space and specifically address the following aspects ...

The Internal Magnetic Field Structure of Interplanetary Coronal Mass Ejections in the Heliosphere

The Astrophysical Journal
Interplanetary coronal mass ejections (ICMEs) are major drivers of heliospheric disturbances and space-weather effects. Here, we present a multispacecraft study of 96 magnetic clouds (MCs) distributed over a broad range of heliocentric distances and ...

Estimation of the Energy Involved in a Solar Coronal Mass Ejection Using Spectroscopic Observations in the 5303 Å Emission Line

The Astrophysical Journal Letters
While the amount of solar coronal energy flux leaving the “quiet” Sun, coronal holes, and active regions has been estimated by many, similar calculations for transients like coronal mass ejections (CMEs) based on observations are few. Using spectroscopic

3D Non-equilibrium Ionization and Spectroscopic Modeling of Coronal Mass Ejections. II. CME Energy Budget

The Astrophysical Journal
Coronal mass ejections (CMEs) release between ≈10 ^30 and 10 ^33 erg of energy into the corona; however, their detailed energy budget is difficult to constrain.

Discrepancies in the Properties of a Coronal Mass Ejection on Scales of 0.03 au as Revealed by Simultaneous Measurements at Solar Orbiter and Wind: The 2021 November 3–5 Event

The Astrophysical Journal
Simultaneous in situ measurements of coronal mass ejections (CMEs), including both plasma and magnetic field, by two spacecraft in radial alignment have been extremely rare.

Comparative Analysis of Properties of Coronal Mass Ejections at High and Low Apparent Latitudes in 1996–2025

The Astrophysical Journal
This study examines the statistical properties of coronal mass ejections (CMEs) over two and a half solar cycles (1996–2025) using coronal observations from the SOHO LASCO CDAW and CACTus catalogs, supplemented by sunspot number records and in situ ...
