                         (Dst < -100 nT) that occurred during solar cycle 23 (1997-2005). 
                         It was found that the most common interplanetary structures 
                         leading to the development of an intense storm were: magnetic 
                         clouds, sheath fields, sheath fields followed by a magnetic cloud 
                         and corotating interaction regions leading high speed streams. 
                         However, the relative importance of each of those driving 
                         structures was found to vary with the solar cycle phase. We divide 
                         the cycle in three phases (rising, maximum and declining) and 
                         explain the differences. We also discuss about the 
                         geoeffectiveness of each of the four main interplanetary driving 
                         structures.",
