Nine Fs(t) wave packets of Pc1 geomagnetic pulsations recorded at the Sogra observatory were subjected to detailed Fourier analysis. The spectra have pronounced maxima at the second and third harmonics, 2fs0 = 2.097 Hz, 3fs0 = 3.146 Hz, fs0 = 1.044 Hz. The relative values of their amplitudes, delta Ss(2) = 0.08-0.19 and delta Ss(3) = 0.03-0.08, significantly exceed the amplitudes of spectrum satellites and the plasma-oscillation background in the vicinity of these frequencies. Two pairs of intense symmetric satellites of modulation type with frequencies of 0.031 and 0.047 = H2 were identified, which determine the third and fourth resonant frequencies of the magnetospheric cavity.
