Coronal Mass Ejection
CME

Purpose:: The purpose of the Coronal Mass Ejection Forecasting project is to provide a long-term warning of the potential eruptive events from the Sun. Sigmoid (S-shaped) active regions know to have a highter than average probability for producing eruptive events such as coronal mass ejections (CME) than other regions. The appearance of the sigmoidal shape can precede the CME by one to three days; the CME then take 2 to 3 days to travel from the Sun to the distance of the Earth's orbit. CMEs that impact the Earth's magnetosphere produce geomagnetic disturbances. This application can offer longer warning interval of the possiblity of geomagnetic activity.
Input:: Solar coronal image data, auxiliary information on active region flares, CME and Type II occurences, solar wind eregetic particle fluxes and magnetic fields, and geomagnetic K- index.
Output:: The output of the Coronal Mass Ejection software is a map showing the locations of sigmoidal solar active regions detected as well as timelines showing the appearance of sigmoids and the occurrence of flares in each solar active region.
