THE NON-CYCLIC VARIATION DURING QUIET DAYS
Abstract
New methods of studying Sq during the IGY have revealed a clear pattern of the non-cyclic variation field which was not discernible form earlier studies. The field is mainly zonal about the geomagnetic axis, though there are significant departures from axial symmetry. The zonal part corresponds closely to a uniform field plus a dipole field along the geomagnetic axis. The relative values of these two parts accord well with the assumption that the internal part arises from currents induced in the earth by Dst varia tions. The relationship between the non-cyclic variations and hourly values of equatorial Dst is discussed.
