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 ...

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,

Dynamics of coronal mass ejections [PDF]
Astronomy and Astrophysics, 2008 Context. Coronal and interplanetary propagation of coronal mass ejections (CMEs) is strongly affected by aerodynamic drag. Aims. The dependence of the drag acceleration on the mass of the CMEs is investigated to establish a quantitative empirical relationship, which might be important in semi-empirical space-weather forecasting. Methods.

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.

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.

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.

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 ...
