Fig. 7.From: ULF waves in the outer magnetosphere: Geotail observation 1 transverse waves(a) Waveforms of ion flow at GTL, solar wind dynamic pressure and IMF variations in GSM coordinates. (b) High-pass filtered records from five stations, HUA in dip equator, CHB in cusp latitudes, NAQ, FCC and YKC in the auroral oval. The arrows indicate local magnetic noon at HUA and NAQ. Note that the waveform at HUA is very similar to those at high latitude stations.Back to article page
