... The ring current (e.g., Frank, 1967) consists of geomagnetically trapped 10 - 200 keV ions (mainly H + , He + , and O + ) and electrons that drift azimuthally around the Earth at radial distances of about 2-7 Re (Earth radii), overlapping the radiation belt region. ... This index can be used to monitor the development of geomagnetic storm (see also geomagnetic activity ), as the main signature (actually definition) of the storm main phase is the build-up of an enhanced ring current. ...
