The source regions of solar coronal mass ejections
Solar Physics, 1990Knowledge of the origin of the solar coronal mass ejection (CME) may be crucial to our understanding of several active solar phenomena, such as flares, as well as to the structure and stability of the corona and the prediction of interplanetary disturbances.

Coronal mass ejections: Solar cycle aspects
Advances in Space Research, 2007Abstract Research in the area of coronal mass ejections (CMEs) is now mature, since their discovery coincided with the first coronagraph that was flown in space in 1971. However, the continuity of space coronagraphs and similar instruments has allowed the detection and measurement of CMEs over almost three consecutive solar cycles.

Solar Storms, Coronal Mass Ejections, and Solar Shields
2021If one were to survey the general public about serious concerns for the future, what would they say? Many of the answers would be predictable. Pandemics, climate change, and weapons of mass destruction would very likely head the list. Others with a broader perspective might mention asteroids and comets, genetic engineering, and pollution.

Solar Flares and Coronal Mass Ejections
Annual Review of Astronomy and Astrophysics, 1992Attempts to clarify the nature of the terrestrial effects of solar activity and variability continue at an increasing pace. While mechanisms relating possible changes in terrestrial weather patterns to changes in solar lumin osity remain elusive, it has long been thought that intense geomagnetic storms and interplanetary disturbances can be traced ...

On the origin of solar halo coronal mass ejections
Письма в астрономический журнал: Астрономия и космическая астрофизика, 2019We present an investigation of halo coronal mass ejections (HCMEs) to understand the origin of HCMEs which is very important because HCMEs are regarded as main causes of heliospheric and geomagnetic disturbances. In this study, we have investigated 313 HCMEs observed during 1996–2012 by LASCO, coronal holes (CHs) and solar flares phenomena.

Coronal mass ejections of solar cycle 23
Journal of Astrophysics and Astronomy, 2006I summarize the statistical, physical, and morphological properties of coronal mass ejections (CMEs) of solar cycle 23, as observed by the Solar and Heliospheric Observatory (SOHO) mission. The SOHO data is by far the most extensive data, which made it possible to fully establish the properties of CMEs as a phenomenon of utmost importance to Sun-Earth ...

Decoding the Pre-Eruptive Magnetic Field Configurations of Coronal Mass Ejections
Space Science Reviews, 2020A clear understanding of the nature of the pre-eruptive magnetic field configurations of Coronal Mass Ejections (CMEs) is required for understanding and eventually predicting solar eruptions. Only two, but seemingly disparate, magnetic configurations are

Coronal Mass Ejections and Solar Energetic Particle Events,
AIP Conference Proceedings, 1996We review the observations relating solar energetic particle (SEP) events to coronal mass ejections (CMEs). Nearly every gradual SEP event is associated with a fast (v≳400 km/s) CME, which is presumed to drive a coronal shock that accelerates the SEPs.

The Sun’s magnetized plasma atmosphere is the source of various forms of activity, the most dramatic of which are coronal mass ejections (CMEs). These ejections are a bulk expulsion of plasma and magnetic field that travel out into the heliosphere, causing space weather effects on any planetary environments that they interact with.

Coronal Mass Ejection Research Using Solar Mass Ejection Imager (SMEI) Data
2007Abstract : This report results from a contract tasking University of Birmingham as follows: The contractor will investigate data collected on coronal mass ejections (CME), and attempt to construct images of CMEs as they move towards the earth and predict their arrival.
