SOLAR ACTIVITY WAS MODERATE. REGION 8993 (S23W58) WAS THE MOST ACTIVE GROUP TODAY, PRODUCING AN M1/SF AT 0805Z, AS WELL AS ADDITIONAL, UPPER-LEVEL C-CLASS EVENTS. THE REGION SHOWED SOME GROWTH IN THE TRAILING PART OF THE REGION. REGION 8996 (S21E44) IS THE LARGEST GROUP ON THE DISK WITH 1140 MILLIONTHS AREA, AND WAS ABLE TO MUSTER A COUPLE UPPER-LEVEL C-CLASS EVENTS. REGION 8998 (S13E54) SHOWED SOME GROWTH TODAY, AND ALSO PRODUCED A C-CLASS EVENT. NEW REGION 9002 (N18E76) ROTATED INTO VIEW TODAY AS A LARGE, H-TYPE SUNSPOT: THE TRAILING PORTION OF THE REGION MAY BECOME APPARENT OVER THE NEXT 24 HOURS. A LONG DURATION C-CLASS EVENT OCCURRED FROM 13/2301 TO 14/0020Z. THIS EVENT WAS ASSOCIATED WITH A FILAMENT DISAPPEARANCE IN THE NORTHEAST QUADRANT AND A CORONAL MASS EJECTION WHICH BECAME VISIBLE IN THE LASCO C2 FIELD OF VIEW AT 0026Z. THE MASS EJECTION DOES NOT APPEAR TO BE EARTHWARD DIRECTED.

SOLAR ACTIVITY IS EXPECTED TO BE MODERATE OVER THE NEXT THREE DAYS, WITH REGIONS 8993 AND 8996 BEING THE MOST LIKELY SOURCES FOR M-CLASS FLARES, ALTHOUGH 8989 (N16W54) AND 8998 COULD ALSO CONTRIBUTE. THERE IS A SLIGHT CHANCE FOR A MAJOR FLARE DURING THE NEXT 72 HOURS.

THE GEOMAGNETIC FIELD RANGED FROM QUIET TO MINOR STORM LEVELS. QUIET TO UNSETTLED LEVELS DOMINATED FOR MOST OF THE DAY, BUT A PERIOD OF ENHANCED ACTIVITY (ACTIVE TO MINOR STORM) WAS OBSERVED BETWEEN 0000-0300Z. THERE WAS NO CLEAR-CUT SOLAR WIND SIGNATURE TO ACCOUNT FOR THE SUBSTORM, OTHER THAN TWO HOURS OF MODERATELY ENHANCED NEGATIVE BZ FROM 0000-0200Z.

THE GEOMAGNETIC FIELD IS EXPECTED TO BE MOSTLY UNSETTLED OVER THE NEXT THREE DAYS.
