Research Progress on Detection of Coronal Mass Ejection

A Coronal Mass Ejection (CME) is a large-scale, severely explosive phenomenon that is the main solar outburst affecting the Earth. As this kind of explosion will cause serious interference to the terrestrial environment, detecting CMEs is of great significance for forecasting severe space weather. In order to more clearly sort out the existing CME detection methods, this paper analyzes and summarizes the typical methods. Firstly,CMEs and their characteristics are introduced. Then, CMEs detection methods are summarized and analyzed from two aspects:manual methods and automatic methods. Finally, problems of the current algorithms are discussed and the future research direction is proposed.
