Abstract : The following problems are studied: (1) The frequency distribution of magnetic storms: large as well as moderate magnetic storms occur more frequently on some days during the period of solar rotation than others. (2) The periodic variation of the daily K index total during the period of solar rotation: the K index is a comparatively more objective standard for indicating geomagnetic activity. Curves showing its variation are primarily consistent with the frequency distribution curves of international magnetically disturbed days. (3) The periodic variation of the daily average of the geomagnetic field's horizontal intensity during the period of solar rotation: similar to the case of the K index, the effect of solar rotation on the horizontal intensity is also very pronounced. The crest occurs within the period of solar rotation when there are fewer disturbed days and the trough occurs when there are more disturbed days. The time lag is approximately one day in both cases.
