Spectral characteristics of Pc 3 and Pc 4/5 magnetic pulsation bands observed near L = 6
The relationships among Pc 3, Pc 4, and Pc 5 activities observed at ground stations near L = 6 are clarified by comparing their dynamic spectral structures. It is found that there are two predominant spectral bands throughout the daytime with frequencies of about 20-80 mHz and about 3-10 mHz. At synchronous orbit, corresponding spectral bands are seen in the frequency-time spectra of the azimuthal component which generally show a clear harmonic structure when the satellite is located at the off-magnetic equator. The result strongly suggests that the 20-80 mHz band is the higher harmonics of standing shear Alfven waves and the 3-10 mHz band is the fundamental mode. Switching of activity between both bands is frequently observed on magnetically quiet days, indicating that the Pc 3 and Pc 4/5 bands are excited by different external driving sources.
