The Borok INTERMAGNET magnetic observatory

The Borok Geophysical Observatory (BGO) was established by the Schmidt’s Instituteof Physics of the Earth of the Russian Academy of Sciences (IPERAS) in 1957 underthe International Geophysical Year program, as a central station of a mid latituderegion observing the ULF geomagnetic field pulsations. In April 2004, the BGO andthe 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, adoptingmodern standard specifications for measuring and recording equipment and transmittingdata in quasi-real time via Geomagnetic Information Nodes to the scientific community.Main results and future developments of the Borok INTERMAGNET observatory arepresented. Almost ten years after the launch of the Orsted magnetic satellite and afew years before that of the ESA Earth Explorer mission Swarm, the role of groundmagnetic observatories such as Borok as evolved but remains essential.
