Description

The new index of recurrence of enhanced geomagnetic activity is compared with the latitudinal and longitudinal distribution of solar magnetic fields and prominences for the recent two eleven-year cycles of solar activity. It is demonstrated that the streamers of the solar wind causing the considerable enhancement and regularity in recurrences of large geomagnetic disturbances during the descending phase and before the end of an eleven-year cycle, are anchored into the system of magnetic fields formed by the fields of the old eleven-year cycle of solar activity.
