Entry of Plasma Sheet Particles into the Inner Magnetosphere Observed by POLAR/CAMMICE
Statistical results are presented from Polax/CAMMICE measurements of events during which the plasma sheet ions have penetrated deeply into the inner magnetosphere. Owing to their characteristic structure in energy-time spectrograms, these events are called "intense nose events." Almost 400 observations of such structures were made during 1997. Intense nose events axe shown to be more frequent i...
متن کاملInjection of a bubble into the inner magnetosphere
[1] Magnetic reconnection in the magnetotail or other forms of current sheet disruption are believed to produce plasma bubbles, which consist of flux tubes that have lower entropy content PV than their surroundings. We present an initial Rice-Convection-Model-based simulation of the injection of a bubble into the inner magnetosphere and explore the consequences on ring current formation. As the...
متن کاملSubstorm inner plasma sheet particle reduction
[1] Geotail measurements from within the equatorial inner plasma sheet at r 10–13 RE are used to show that a reduction in equatorial plasma pressure within the current wedge is a general feature of substorms and that this decrease is simultaneous with the wellknown expansion phase increase in energetic particle fluxes. The decrease in pressure is found to be due to a decrease in particle fluxes...
متن کاملThe statistical studies of the inner boundary of plasma sheet
The penetration of plasma sheet ions into the inner magnetosphere is very important to the inner magnetospheric dynamics since plasma sheet ions are one of the major particle sources of ring current during storm times. However, the direct observations of the inner boundary of the plasma sheet are fairly rare due to the limited number of satellites in near equatorial orbits outside 6.6RE. In thi...
متن کاملTransport of energetic electrons into Saturn’s inner magnetosphere
[1] We present energetic electron data obtained by Cassini’s Magnetospheric Imaging Instrument in the inner magnetosphere of Saturn. We find here that inward transport and energization processes are consistent with conservation of the first two adiabatic invariants of motion. We model several injections near local midnight, one injection has a maximum energy of hundreds of keV, that are consist...
