TUESDAY 0330 UTC JULY 27, 2004

 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 NEGATIVE. I WOULD EXPECT TO SEE A SEVERE KP-8/G4 TO EXTREME KP-9/G5
GEOMAGNETIC STORM AT MID LATITUDES. THERE IS ALSO A POSSIBILITY OF VISIBLE
AURORA DOWN TO 28 DEG. NORTH LATITUDE.

 MONDAY 2100 UTC JULY 26, 2004

 THE STRONG TO SEVERE GEOMAGNETIC STORMING OF THE PAST 24 HOURS HAS ENDED.
ANOTHER GEO-EFFECTIVE (EARTH FACING) CORONAL MASS EJECTION IS CURRENTLY
ENROUTE TO EARTH. IT SHOULD STRIKE OUR MAGNETIC FIELD SOMETIME DURING UTC
TUESDAY JULY 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 GEOMAGNETIC STORM LEVEL OF G4 SEVERE. DURING THE SAME TIME PERIOD THE
BOULDER K INDEX HAS REACHED A LEVEL OF 7, WHICH IS A GEOMAGNETIC STORM LEVEL
OF G3 STRONG.
