Abstract

Borok Geophysical Observatory was created as an experimental base of the Schmidt Institute of Physics of the Earth to carry out natural observations of ultralow-frequency geomagnetic pulsations during the International Geophysical Year. The continuous observation data allowed to solve problems of solar-terrestrial physics and to develop methods of near-earth gas-plasma shells diagnostics. Now the continuous geomagnetic observations have been expanded by measurements of geomagnetic variations and the main magnetic field, including absolute magnetic measurements. Geomagnetic field variations are recorded by means of a fluxgate-magnetometer operated within the Sub-Auroral Magnetometers Network SAMNET and made by the University of York (Great Britain). The main geomagnetic field components are recorded within the framework of the international program INTERMAGNET (http://www.intermagnet.org) by scalar and vector magnetometers manufactured by the Institute of Earth Physics of Paris (France). The absolute magnetic measurements are made twice a week. The geomagnetic observation data in near real time mode comes via local data logging network to the database of the mid-latitude Borok Geophysical Observatory (http://geobrk.adm.yar.ru), as well as the data of continuous observations of telluric currents, atmospheric electric field, atmosphere electric current density, some meteorological and aerodynamic parameters of the surface atmosphere and the planetary boundary layer.
