                         -100 nT ) were identified, in which their main phases were totally 
                         or partially associated with the presence of intense 
                         interplanetary Sheath-Bz magnetic fields that seem to have 
                         originated from the interaction of an ICME-Shock with fluctuating 
                         (Alfvenic) - Bz fields of a simultaneously present High Speed 
                         Stream. This set of events represent a substantial fraction ( 
                         ~30%) of geoeffective Sheath - events that led to the occurrence 
                         of intense storms during solar cycles 23 and 24. In addition to 
                         such an interaction process to explain the origin of these largely 
                         geoeffective sheath-Bz field events, other candidate processes 
                         will be argued to may also have played a role for that origin,
