Coronal mass ejections (CME)
firstname.lastname@example.org - last update: 22 December 1998, 1450 UT (RR)
Coronal mass ejections (CME) are huge bubbles of gas ejected from
the Sun over the course of several hours
(Tousey, 1973; Brueckner, 1974; MacQueen et al., 1974; Gosling et al., 1974;
for a recent review, see Hundhausen, 1996).
They seem to be more related to prominence eruptions than solar
flares. When travelling out from the Sun,
term interplanetary CME (or ICME) is often used.
There are more CME events during maximum solar
cycle years than during minimum years: number of daily events increase
from about 0.5 to about 2.5.
It has been shown that the major geomagnetic storms
are created by CMEs hitting the Earth.
