Outer magnetosphere topology and Pc5 ULF waves at high-latitudes / S.T. Ables, B.J. Fraser, F.W. Menk, D.A. Neudegg, R.J. Morris, Liu Ruiyuan.

Abstract: Induction magnetometer data recorded in 1996 at three closely-spaced sites near Davis station, Antarctica, were examined for ionospheric signatures of outer magnetosphere and cusp/cleft regions. Cross-phase analysis of 1-10 mHz band using pure-state filtering techniques reveal diurnally varying field line resonances embedded in the spectra, while interstation phase lag measurements indicate azimuthal propagation of waves away from local magnetic noon. Using T96 external field model, cross-phase measurements are put in context of diurnally changing field line topology due to compression at sub-solar region and stretching along dawn and dusk flanks, suggesting field line stretching as an alternative or additional explanation to the Kelvin-Helmholtz instability for azimuthal wave propagation. A wave cusp meridian identified in propagation data shows variable location about local magnetic noon which is under control of IMF By and shows same well-known behaviour as cusp to these variations.
