List of coronal mass ejections
The following contains a list of coronal mass ejections. A coronal mass ejection (CME) is a massive burst of solar wind and magnetic fields rising above the solar corona or being released into space. Most ejections originate from active regions on the Sun's surface, such as groupings of sunspots associated with frequent flares.
