Direct measurements of the ionospheric convection variability near the cusp/throat
[1] For the first time precise measurements obtained using Super Dual Auroral Radar Network (SuperDARN) radars are used to quantify the temporal variability in the convection velocity and identify the cause of the variations for a particular event located in the vicinity of the cusp. Using SuperDARN line-of-sight (LOS) Doppler velocities near 1200 magnetic local time and a standard fitting tech...
متن کاملThe dayside ultraviolet aurora and convection responses to a southward turning of the interplanetary magnetic field
We examine the large-scale ultraviolet aurora and convection responses to a series of flux transfer events that immediately followed a sharp and isolated southward turning of the IMF. During the interval of interest, SuperDARN was monitoring the plasma convection in the dayside northern ionosphere, while the VIS Earth Camera and the Far Ultraviolet Imager (UVI) were monitoring the northern hemi...
متن کاملObservations of convection in the dayside magnetosphere by the beam instrument on Geotail
We report observations of magnetospheric convection by the beam instrument, EFD-B, on Geotail. The region analyzed in this study is mainly the afternoon sector of the magnetosphere between L = 9.7−11.5. When the instrument is operated, electron beams are emitted from guns and some of them return to detectors attached to the main body of the satellite. However, we find that the return beams are ...
متن کاملCoordinated Cluster/Double Star and ground-based observations of dayside reconnection signatures on 11 February 2004
A number of flux transfer events (FTEs) were observed between 09:00 and 12:00 UT on 11 February 2004, during southward and dawnward IMF, while the Cluster spacecraft array moved outbound through the northern, highaltitude cusp and dayside high-latitude boundary layer, and the Double Star TC-1 spacecraft was crossing the dayside low-latitude magnetopause into the magnetosheath south of the eclip...
