摘要: [1] We present a case study of Field Line Resonances (FLRs) in the dayside magnetosphere, observed both electric and magnetic field components at multiple L-shells near equator. The event measured by five THEMIS probes nearby GOES Geotail satellites provides unique opportunity to differentiate between temporal spatial characteristics FLRs. Narrow-band FLRs were excited globally different frequencies matching local line resonant frequency. In conjunction with sharp increase upstream solar wind density, prompt intensification FLR power was L-shells, simultaneously amplitudes.
