Solar origin Bs events (long intervals of large southward interplanetary magnetic field) is one of the primary cause of intense geomagnetic disturbances with the Bs component the more important quantity. In this paper, magnetic configurations of three active regions, AR8100, AR8375 and AR9026 are analyzed in order to explore the mechanisms of the relative Bs events. Each of the three regions generates several flares that associated with halo CMEs. The subsequent Bs events are identified unambiguously to associate with these CMEs. We measured tilts of the axis of the active regions, calculated twists of magnetic fields, estimated magnetic field structures of the active regions, and analyzed evolutions and characteristics of related flares/CMEs. We then investigate possible relationships of those properties with the subsequent Bs events, and discuss mechanisms of Bs events.
