                         solar and interplanetary sources of intense geomagnetic storms 
                         have been discussed. We consider the very intense geomagnetic 
                         storms that occurred during Solar Cycle 23 by setting a value of 
                         Dstmin <= \−200 nT as threshold. We have identified and 
                         characterized the solar and interplanetary sources of each storm. 
                         After this, we investigate the overall characteristics of the 
                         interplanetary (IP) main-phase storm driver, including the time 
                         arrival of the shock/disturbance at 1 AU, the type of associated 
                         IP structure/ejecta, the origin of a prolonged and enhanced 
                         southward component (Bz ) of the IP field, and other 
                         characteristics related to the energy injected into the 
                         magnetosphere during the storm.",
