We report ground based, low frequency heliograph (80 MHz), spectral (85–35 MHz), and polarimeter (80 and 40 MHz) observations of drifting, non-thermal radio continuum associated with the “halo” coronal mass ejection that occurred in the solar atmosphere ...

Forces governing coronal mass ejections
Advances in Space Research, 2006Kinematics of CMEs is analyzed to get an insight into the properties of forces partaking in the eruption. It is demonstrated that the Lorentz force plays a dominant role within a distance of a few solar radii. In the distance range 1– 30 solar radii, the inferred values of the Lorentz-force acceleration aL on average decrease with the ...

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 ...

Acceleration of coronal mass ejections
Journal of Geophysical Research: Space Physics, 2003The acceleration of coronal mass ejections (CMEs) is examined focusing on three specific questions raised by observations: (1) what determines the height beyond which a CME exhibits no rapid acceleration, (2) why is the main acceleration of CMEs typically limited to below 2–3 solar radii, and (3) are distinct mechanisms required to explain the apparent

Dependence of solar proton events on their associated activities: Coronal mass ejection parameters
, 2012[1] In this study we have examined the occurrence probability of solar proton events (SPEs) and their peak fluxes depending on coronal mass ejection (CME) parameters, linear speed (V), angular width (AW), and location (L).

Initiation of Coronal Mass Ejections
2003Abstract : The over-arching objective of this research was to improve the quantitative basis for prediction of the occurrence of Coronal Mass Ejections (CMEs) and their impact on space weather. The most directly useful discovery, from the point of view of Space Weather forecasting, is that a CME associated with an erupting X-ray sigmoid is more likely ...
