Coordinated observation of field line resonance in the mid-tail
Standing Alfvén waves of 1.1 mHz (~15 min in period) were observed by the Cluster satellites in the mid-tail during 06:00-07:00 UT on 8 August 2003. Pulsations with the same frequency were also observed at several ground stations near Cluster's footpoint. The stand...

| description |
Standing Alfvén waves of 1.1 mHz (~15 min in period) were
observed by the Cluster satellites in the mid-tail during 06:00-07:00 UT on
8 August 2003. Pulsations with the same frequency were also observed at
several ground stations near Cluster's footpoint. The standing wave
properties were determined from the electric and magnetic field measurements
of Cluster. Data from the ground magnetometers indicated a latitudinal
amplitude and phase structure consistent with the driven field line
resonance (FLR) at 1.1 mHz. Simultaneously, quasi-periodic oscillations at
different frequencies were observed in the post-midnight/early morning
sector by GOES 12 (<i>l</i><sub>0</sub>≈8.7), Polar (<i>l</i><sub>0</sub>≈11-14)
and Geotail (<i>l</i><sub>0</sub>≈9.8). The 8 August 2003 event yields rare and interesting
datasets. It provides, for the first time, coordinated in situ and
ground-based observations of a very low frequency FLR in the mid-tail on
stretched field lines. |
