Coronal Mass Ejections (CMEs) are transient events in which large amounts of plasma are ejected from the solar corona. Coronal mass ejections release huge quantities of electromagnetic radiations into space above the Sun’s surface, either near the corona or farther into the planet system. The ejected material is plasma consisting primarily of electrons and protons but may contain small quantities of heavier element such as helium, oxygen and even iron. It is associated with enormous changes and disturbances in the coronal magnetic field. The usual method of observations of Coronal Mass Ejections (CMEs) is in visible light using coronagraphs. Since CMEs are composed primarily of plasma, they therefore contain large amount of free electrons and the light observed are scattered and bounce off these electrons through the Thomson Scattering Process (TSP). In this paper, the dynamics of Coronal Mass Ejections (CMEs) are surveyed through the Thomson Scattering theory by presenting the mathematical equations governing the observation of this phenomenon.
