✦ Synopsis

The distinction between faint and bright sources of the slowly varying component of the solar microwave emission (Paper lI) is applied to statistics of the geomagnetic activity. Superposed epoch diagrams (recurrent disturbances excluded) show that the increased number of disturbed days after the CMP of sunspot groups can almost exclusively be ascribed to the spot groups associated with faint sources. The variation of the disturbance amplitude with the heliographic latitude of the spot groups is discussed. A tentative model for the solar-wind enhancement associated with a faint source is presented.
