Dynamic Structure of the Inner Magnetosphere
1978During intervals of pronounced geomagnetic activity, called magnetic storm, the low-latitude magnetic field becomes depressed at all local times, indicating the formation of a current circuit that encircles the earth. Since the depression is too great to be attributed to an expansion of the magnetosphere, the ring current is thought to develop within ...

Energetic particle penetrations into the inner magnetosphere
Journal of Geophysical Research: Space Physics, 1980Data from Explorer 45 (S³‐A) instruments have revealed characteristics of magnetospheric storm or substorm time energetic particle enhancements in the inner magnetosphere (L ≲5). The properties of the ion ‘nose’ structure in the dusk hemisphere are examined in detail.

Direct effects of the IMF on the inner magnetosphere
2005Several direct and well-established inner-magnetospheric effects following changes in Interplanetary Magnetic Field direction find natural explanations in terms of the Rice Convection Model. A southward turning of the IMF normally causes an increase in both cross-polar-cap potential drop and in polar-cap size.

Remote sensing the state of the inner magnetosphere
IEEE Conference Record - Abstracts. 2002 IEEE International Conference on Plasma Science (Cat. No.02CH37340), 2003Summary form only given. The terrestrial magnetosphere is a plasma filled cavity carved out of the solar wind by the Earth's magnetic field. This plasma originates from both the upper atmosphere and the solar wind, and its presence has a significant effect of the topology of the magnetospheric magnetic field. Particularly at high geomagnetic latitudes,

Computer Modeling of Events in the Inner Magnetosphere
2013The first effort at computer simulating the behavior of the inner magnetosphere during a substorm-type event on 19 September 1976 was completed. The computer model simulates many aspects of the behavior of the closed-field-line portion of the earth's magnetosphere, and the auroral and subauroral ionosphere.

Presence of cavity resonances in the inner magnetosphere
2020<p>In the inner magnetosphere there are sharp plasma boundaries that can cause resonance cavities. The four Cluster satellites move in a string-of-pearls configuration at perigee (at L=4-5) so that they are spatially well separated but their separation is still short that at least some of them are simultaneously at different ...

Solar Particle Access into the Inner Magnetosphere
1974There are four modes of access of energetic particles into the inner magnetosphere, defined here as the region of ‘closed’ field lines, i.e. regions of latitude below, for instance, the 40 keV electron boundary. These are direct entry to all latitudes above the cut-off, longitudinal drift from the nightside to the dayside pseudotrapping region, radial ...
