Probing the relationship between electromagnetic ion cyclotron waves and plasmaspheric plumes near geosynchronous orbit
[1] Plasmaspheric plumes created during disturbed geomagnetic conditions have been suggested as a major cause of increased occurrences of electromagnetic ion cyclotron (EMIC) waves at these times. We have catalogued occurrences of strong Pc1 EMIC waves from 1996 through 2003 at three automated geophysical observatories operated by the British Antarctic Survey at auroral zone latitudes in Antarc...
متن کاملSimultaneous remote-sensing and in situ observations of plasmaspheric drainage plumes
Plasmaspheric drainage plumes are regions of dense plasma that extend outward from the plasmasphere into the outer magnetosphere. We present observations of plumes for two events, 2 June 2001 and 26–27 June 2000. Our observations come from two sources. A global perspective is provided by the IMAGE extreme ultraviolet (EUV) imager, which routinely obtains images of the helium portion of the plas...
متن کاملTwostream modeling of plasmaspheric refilling
Plasmaspheric refilling on an L = 4 flux tube was studied by using a time-dePendent, hydrodynamic plasmaspheric flow model in which the ion streams from the tWO hemispheres are treated as distinct fluids. In the model the continuity, momentum, and energy equations of a twoion (O + and H+), quasi-neu.tral, currentless plasma are solved along aclosed geomagnetic field line; diffusive quilibrium i...
متن کاملOrigin and evolution of deep plasmaspheric notches
[1] Deep plasmaspheric notches can extend over more than 2 RE in radial distance and 3 hours MLT in the magnetic equatorial plane, as observed by the extreme ultraviolet (EUV) imager on the IMAGE mission. They are among the largest evacuated features in the exterior plasmaspheric boundary. They can last for days and exhibit a variety of shapes. It appears that weak convection and limited erosio...
متن کاملResponse of plasmaspheric configuration to substorms revealed by Chang’e 3
The Moon-based Extreme Ultraviolet Camera (EUVC) of the Chang'e 3 mission provides a global and instantaneous meridian view (side view) of the Earth's plasmasphere. The plasmasphere is one inner component of the whole magnetosphere, and the configuration of the plasmasphere is sensitive to magnetospheric activity (storms and substorms). However, the response of the plasmaspheric configuration t...
