                         sources for selected major geomagnetic storms (disturbance storm 
                         index-Dst<=\−100 nT) that occurred in OctoberNovember 2003. 
                         The CME data were obtained from the LASCO CME Catalog. We 
                         estimated time of flight of the CMEs from Sun to near-Earth space 
                         from their speed obtained from the linear fit, and identified the 
                         geoeffective ones. We analyzed the CMEs produced by the active 
                         region NOAA AR10486 from October 22 to November 4, during its 
                         passage across the visible solar disk. This huge sunspot region 
                         produced many X flares, the largest ones accompanied by intense 
                         >100 MeV SEP events and associated with full halo CMEs that mostly 
                         propagated in the western hemisphere, and caused strong 
                         geomagnetic storms. These results are in agreement with the idea 
                         that the fast and large CMEs propagating in a disturbed solar wind 
                         could accelerate energetic particles and intensify the magnetic 
                         storms.",
