Abstract:
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. Coronal mass ejections are often associated with other forms of solar activity, most notably solar flares, but a causal relationship has not been established. Most ejections originate from active regions on the Sun’s surface, such as groupings of sunspots associated with frequent flares. Near solar maxima, the Sun produces about three CMEs every day, whereas near solar minima there is about one CME every five days.
