Variations of geomagnetic field by ionospheric and magnetospheric sources during extrastorm of 20-21 November 2003 are separated. It is shown that at the beginning of the storm events developed in particular way. The part of variations generated by ionospheric currents in the middle latitudes is evaluated.
