After a brief review of magnetospheric and interplanetary phenomena for intervals with
enhanced solar wind‐magnetosphere interaction, an attempt is made to define a …

The terrestrial ring current is an electric current flowing toroidally around the Earth, centered
at the equatorial plane and at altitudes of∼ 10,000–60,000 km. Changes in this current are …

The time evolution of the ring current population during the recovery phase of a typical
moderate magnetic storm is studied, using a newly developed kinetic model for H+, He+ and …

Abstract The IMAGE Extreme Ultraviolet Imager (EUV) provides our first global images of the
plasmasphere by imaging the distribution of He+ in its 30.4-nm resonance line. The images …

One year's worth of magnetospheric plasma analyzer data from three Los Alamos
geosynchronous satellites are used for a statistical study of proton and electron fluxes at …

Simulation studies of the Earth's radiation belts and ring current are very useful in
understanding the acceleration, transport, and loss of energetic particles. Recently, the …

The decay of the major ion species which constitute the ring current is studied by solving the
time evolution of their distribution functions during the recovery phase of a moderate …

This paper presents the first simultaneous in situ measurements of the large‐scale
convection electric field and the ring current induced magnetic field perturbations in the …

A new view of the ring current as an active element in the geospace system has emerged in
which the ring current responds not only to changing convection electric fields imposed by …

Electromagnetic ion cyclotron (EMIC) waves and magnetosonic waves are commonly
observed in the Earth's magnetosphere associated with enhanced ring current activity …
