Summary

The Q index at three antarctic stations during the International Geophysical Year is examined. The monthly diurnal and yearly variation is discussed and harmonically analyzed for disturbed, quiet, and all days. Maxima of magnetic activity are discussed in connection with the direction and position of ionospheric current systems. In winter Macquarie Island and Mawson are characterized as auroral zone stations with a postmidnight maximum, whereas Mirnyy shows very slight disturbance in the horizontal components. In summer Macquarie Island and Mawson are characteristic of the Stagg transition zone with two maxima of disturbance activity, whereas Mirnyy displays a single midday maximum.
