Geomagnetic pulsations in the frequency range of Pc1 pearl waves with the dynamic spectra having a very narrow spectrum width at the beginning of the event and a very broad spectrum width in the later part of the event are analyzed. One of the observed events shown by the dynamic spectrum resembles a goose with the beak at the beginning of the event and with the wing in the later part of the event.
