Abstract Geomagnetic activity, if analysed not from the viewpoint of individual solar cycles but of polarity of the main solar dipole field, shows a 12-month wave with maxima alternatively at the vernal or autumnal equinoxes. Whether the vernal or the autumnal maximum is greater depends on the polarity of the main solar dipole; the existence of the wave may be explained by the north-south asymmetry in the main solar dipole field. The results favour the southward component of the interplanetary magnetic field as the decisive factor for geomagnetic activity.
