Preferred term
CORONAL MASS EJECTION
Definition
- A disturbance of the Sun's corona involving eruptions from the lower part of the corona and ejection of large quantities of matter into the solar wind. These ejecta sometimes have higher speed, density, and magnetic field strength than is typical for the solar wind. If their speeds relative to the background solar wind are high, they can produce shocks in the plasma that precede them as they move outward. (en)
