The difference between northern and southern hemispheric geomagnetic activity is investigated as a function of the sector polarity pattern of the interplanetary magnetic field. It is found for the year 1964 that sectors with field directed away from the sun are associated with slightly enhanced northern hemisphere activity, and toward sectors are associated with slightly enhanced southern hemisphere activity.
