The use of geomagnetic activity observations in studies of solar wind-magnetosphere coupling and centennial solar change
The source of the semi-annual variation in geomagnetic indices is investigated with regard to its possible origins in the solar wind and within the magnetosphere/ionosphere system. To further this investigation, the patterns of annual' and diurnal variations of the existing long-running aa and...
