| Zusammenfassung |
| On 24 November 2006, simultaneous observations of Pc5 pulsations, electron
precipitation and whistler-mode chorus, as well as solar wind and IMF
parameters have been analyzed based on data from IMAGE magnetometers,
riometer array and temporal VLF station. This paper focuses on the Pc5
pulsations detected at the same time, in the 1–25 millihertz range,
by the [SQUID]2 system (SQUID magnetometer within a Shielding QUalified for Ionosphere Detection)
installed 518 m underground at 43.92° N, 5.48° E. As
expected, the 3-D-frequency spectrum of these mid-latitude [SQUID]2
signals exhibits frequency peaks quasi identical to those observed by polar
stations of close geomagnetic longitude. The signal/noise ratio allows the
observation of the wave polarization and the beatings of the frequencies. As
a result, the possibility of studying, at mid-latitude, magnetic Pc5
pulsations linked with an event in the magnetosphere can improve the
description of both behaviour and propagation of these waves. |
