THE PREVIOUSLY MENTIONED MAJOR CME ARRIVED AT APPROXIMATELY 2250 UTC ON JULY
26, 2004. THE SOLAR WIND VELOCITY HAS EXCEEDED 1000 KM/S AND THE BZ IS VERY

27, 2004, TRIGGERING MORE STRONG TO SEVERE GEOMAGNETIC STORMING.
SUNDAY 1500 UTC JULY 25, 2004
IN THE PAST 12 HOUR PERIOD THE KP INDEX HAS REACHED A LEVEL OF 8, WHICH IS A
