| Popis: | Based on the data from the Vostok station, Antarctica, for the period from 1966 to 1971, the frequency modulation of the serpentine-emission-type (SE) geomagnetic pulsations is studied. The spectral analysis of the selected emission events revealed a number of modulation periods in the interval from 1 to 60 min. The 5-min SE modulation period is most common. The obtained results are compared to the observations of solar atmosphere oscillations. The correspondence of the periods of the SE frequency modulation to the periods of oscillations of the solar photosphere is established. This confirms the previously suggested hypothesis of the existence of a genetic connection between the frequency modulation of the emission and oscillations of the solar surface. |
