The Borok Geophysical Observatory BGO was established by the Schmidt's Institute of Physics of the Earth of the Russian Academy of Sciences IPERAS in 1957 under the International Geophysical Year program, as a central station of a mid latitude region observing the ULF geomagnetic field pulsations. In April 2004, the BGO and the Institute of Physics of the Earth in Paris IPGP installed new magnetometers, after which the observatory gained official INTERMAGNET magnetic observatory status. INTERMAGNET is a global network of cooperating digital magnetic observatories, adopting modern standard specifications for measuring and recording equipment and transmitting data in quasi-real time via Geomagnetic Information Nodes to the scientific community. Main results and future developments of the Borok INTERMAGNET observatory are presented. Almost ten years after the launch of the Oslash;rsted magnetic satellite and a few years before that of the ESA Earth Explorer mission Swarm, the role of ground magnetic observatories such as Borok as evolved but remains essential.
