Short summary
The K index is the classical, commonly used parameter of geomagnetic activity that serves as the measure of local magnetic field variations. This paper presents a unique collection of historical K index values that was formed at the World Data Center for Solar-Terrestrial Physics in Moscow. It includes the results of the K index determination at 41 geomagnetic observatories of the former USSR for the period from July 1957 to the early 1990s.
