An analysis is presented of the dynamic spectra of Pi1B pulsations, pearls, and specific oscillations in the Pc1 range observed at auroral-zone latitudes. It is shown that Pi1B pulsations in auroras and in magnetic fields are observed synchronously and that the frequency-amplitude characteristics of these pulsations in auroras and magnetic fields are morphologically similar. Both types of emission are found to have an ionospheric-origin mechanism, and this mechanism can serve as a basis for determining the energy distribution and evolution of electron fluxes precipitating into the ionosphere. Pi1B bursts can serve to stimulate the development of Pc1 pulsations, morphologically related to irregular oscillations.
