(a) PSDs for the first wave packet and IMF variations from 13:35 (left panels). Three right panels from the top separately show ground spectra of three groups of stations in the polar cap, in cusp latitudes (~73° geomagnetic latitude) and in the auroral oval. Spectra plotted in the bottom panel are those of auroral oval stations in the afternoon sector. (b) PSDs for two intervals from 14:40 and 15:45. Top panels present total PSDs of six high latitude stations in the morning sector. Bottom panels shows PSDs of IMF variations.
