The study was conducted of the dynamics of large-scale structures of the polar region F2, due to the change of the sign of the By-component of the interplanetary magnetic field. It is shown that one of the reasons for non-stationary variations of the ionosphere structure in polar caps can be fast variations of the By-components of MMP. The time of transfer of the ionization language from morning to evening is 3000 s. This process is accompanied by the stratification of the ionization language and the formation of large-scale ionization spots that disintegrate over time.
