The calculation of the magnetic poles movement velocity for quiet days in 1958 and 2017 has been carried out. Seasonal variations of the magnetic poles movement velocity appear, as usual, not as clearly as the daily variations associated not only with the earth's revolution around the sun, but also around its axis.
