- Abstract
Based on the results of instrumental observations of geomagnetic variations at the Mikhnevo Observatory of the Institute of Geosphere Dynamics, Russian Academy of Sciences, and the data from the IERS catalog, it is found that the frequency F of the fundamental spheroidal mode 0S2 of the Earth's free oscillations, distinguished in the spectra of magnetic field variations, changes with time; the values of F are higher when the speed of the Earth's rotation decreases and are lower when it increases. An empirical relationship between the variations in F and the speed of the Earth's rotation is obtained.
