Dobrovolsky2 1Shmidt Institute of Physics of the Earth RAS, Moscow, Russia AbstractWe have digitized and made available for free access analog magnetic records of the Soviet Antarctic expeditions to Vostok station from 1967 to 1971. Despite the deployment of observatories and automatic stations in the polar cap in recent years in Antarctica, these old observations near the geomagnetic pole by a highly sensitive induction magnetometer with a recording frequency of 20 Hz remain unique. These data make it possible to study the nature of specific impulse and wave electrodynamic disturbances in the polar cap and their relationship with dynamic processes in the near-Earth space. Examples of signals and emissions in the polar cap, first recorded at Vostok station: discrete Pc1 pulsations, serpentine emission, and Pc3-4 pulsations. The proposed database will help to increase Russian participation in research on space weather manifestations in Antarctica.
