Abstract: | Solar quiet day variations of the vertical geomagnetic component Sq(Z) have been studied. These show abnormal variations from day to day. The study for the period 1961 to 1976 indicates that, for quite a number of days, the Sq(Z) phase reverses completely. It is concluded that changes in phase of Sq(Z) could be explained by the movement of the Sq current system and the penetration of the Sq southern current system into the northern hemisphere. |
