American Journal of Rising Scholar Activities, 2023 The underlying dynamics of solar processes are a topic of considerable interest, because the events on the surface of the Sun directly affect the environment of our planet. Certain ‘storms’ that erupt in the outer layers of the Sun can propel masses of electrically charged plasma into the solar system. If the path of that material crosses Earth’s orbit,

Detection of Coronal Mass Ejections
2008 15th IEEE International Conference on Image Processing, 2008Coronal mass ejection (CME) events refer to the appearance of a new, discrete, white-light feature (with outward speed) in a coronagraph. The huge amount of data provided by the pertinent instruments onboard the solar and heliospheric observatory (SOHO) and, most recently, the solar terrestrial relations observatory (STEREO) makes the human-based ...

While the first coronal mass ejections (CMEs) were observed with the OSO‐7 white light coronagraph (Tousey, 1973), it was the Skylab coronagraph observations that clearly established CMEs as an important component of solar coronal physics. CMEs have been defined by Hundhausen et al.

Coronal mass ejections and interplanetary shocks
Journal of Geophysical Research: Space Physics, 1985A comparison between Solwind observations of coronal mass ejections (CME's) and Helios 1 observations of interplanetary shocks during 1979–1982 indicates that 72% of the shocks were associated with large, low‐latitude mass ejections on the nearby limb.

Annual Review of Astronomy and Astrophysics, 1984
Sudden expulsions of dense clouds of plasma from the outer atmosphere of the Sun, termed "coronal mass ejections" (CMEs), are the focus of intense observational and theoretical efforts. CMEs are a type of coronal transient, the general name given the disruption of coronal structure.

Radio Signatures of Coronal Mass Ejection Interaction: Coronal Mass Ejection Cannibalism?
The Astrophysical Journal, 2001We report the first detection at long radio wavelengths of interaction between coronal mass ejections (CMEs) in the interplanetary medium. The radio signature is in the form of intense continuum-like radio emission following an interplanetary type II burst. At the time of the radio enhancement, coronagraphic images show a fast CME overtaking a slow CME.

Coronal mass ejections are seen as bright features that move outward through the solar corona at speeds from 10 to about 2,000 km s-1. They involve the expulsion of substantial quantities of plasma from large regions of the corona. The spectacular nature of the largest mass ejections is illustrated in Figure 5.1 by a time sequence of four images ...

AIP Conference Proceedings, 2000
The most dramatic changes in the solar corona occur during coronal mass ejections, or CMEs, during which solar material is propelled outward into the heliosphere from regions in the corona not previously participating in the solar wind expansion. These ejections often produce major solar wind disturbances, large geomagnetic storms, enhancements of ...

On the Coronal Mass Ejection onset and Coronal Dimming
Solar Physics, 2004A comprehensive case and statistical study of CME onsets has been conducted on the solar limb using the CDS, LASCO and EIT instruments aboard the SOHO spacecraft. This is the first dedicated campaign to establish firmly the EUV signatures of CME onsets and is based on a series of low-corona observing campaigns made in 2002. The event database consisted
