Waveform and spectral properties of the H, X component magnetic field data from MDM–EYR pairs for the time intervals of 7–12 Sep 2011. a Time series plot and b dynamic power spectrum of the H component magnetic field at MDM. c Phase of H components at MDM relative to the phase of X components at EYR. d MDM to EYR power ratio. The black dots in (c) and (d) indicate the field line resonance frequency estimated by the cross-phase analysis method. e The equatorial plasma mass density inferred from the field line resonance frequency
