             abstract = "This paper is a study of the relationship between the geomagnetic 
                         storm index Dst and the southward component, Bs, of the 
                         interplanetary magnetic field (IMF) driver. This study was 
                         performed during the ACE observational period (1997-2002), for 
                         which 64 intense geomagnetic storms (Dst <= -85 nT) were analyzed. 
                         After taking into account the propagation time between the L1 
                         point and Earth (similar to 1 h) and the magnetosphere/ring 
                         current response-time to solar wind forcing (similar to 1 h), it 
                         was determined that the average delay between the peak Bs and the 
                         peak Dst values is similar to 2 h. It was also observed that the 
                         Bs value at peak Dst is similar to 75% of the peak Bs value in the 
                         entire event. When these results are analyzed in terms of the 
                         interplanetary electric field, associated with Bz, some 
                         interesting additional studies are indicated, for which some 
                         simple results, of practical space weather forecasting use, are 
                         anticipated.",
