                         (¦¤Dstˇ(C100 nT during 1 h) that occurred during 1996¨C2005. These 
                         events are expected to be better related to geomagnetic induced 
                         current (GIC) events than those events where any geomagnetic index 
                         is far from its quiet time value. At least one full halo CME with 
                         a speed on the plane of sky above 900 km/s participates in every 
                         studied event. The seven events were triggered by interplanetary 
                         signatures, which arise as a consequence of interaction among 
                         different solar ejections. The interaction arises at different 
                         stages from the solar surface, between segments of a filament, to 
                         the interplanetary medium, appearing as ejecta or 
                         multiple-magnetic clouds (MultiMCs). In other cases, shock waves 
                         overtake or compress previous ICMEs and at other times the 
                         interaction also appears between magnetic clouds (MCs) and 
                         streams.",
