SOLAR ACTIVITY BECAME HIGH DUE TO THE LARGE NUMBER OF M-CLASS EVENTS THAT OCCURRED. MULTIPLE REGIONS WERE RESPONSIBLE FOR THIS INCREASE IN ACTIVITY. REGION 8939 (N22E56) PRODUCED THE LARGEST EVENT - AN M4/SF AT 31/1019Z. THIS FLARE ALSO PRODUCED A WEAK TYPE IV AND MINOR CENTIMETER BURSTS. REGION 8939 ALSO PRODUCED M1/SF FLARES AT 31/0755Z, 31/1318Z, AND 31/1655Z. THIS REGION'S SMALL SIZE BELIES ITS M-CLASS FLARE PRODUCTION. REGION 8936 (S14E56) GREW AT A MODERATE PACE DURING THE PERIOD AND EXHIBITED INCREASING MAGNETIC GRADIENTS AND A POSSIBLE DELTA CONFIGURATION. THIS REGION PRODUCED AN M2/2B AT 30/2324Z AND AN M1/SN AT 31/0652Z (WITH A LARGE CORONAL MASS EJECTION). REGION 8925 (S18W32) PRODUCED AN M2/1N AT 31/1901Z. THIS REGION WAS PREDOMINANTLY STABLE AND EXHIBITED SOME MAGNETIC COMPLEXITY. SEVERAL FILAMENTS IN THE NORTH CENTRAL PORTION OF THE SUN FADED DURING THE PERIOD.

SOLAR ACTIVITY SHOULD REMAIN AT A MODERATE LEVEL FOR THE NEXT SEVERAL DAYS. CONTINUED GROWTH IN REGION 8936 WOULD INCREASE THE FREQUENCY OF M-CLASS EVENTS FROM THAT REGION. REGION 8939 COULD CONTINUE TO PRODUCE M-CLASS EVENTS BUT DUE TO ITS SMALL AREA IN WHITE LIGHT, IT IS LIKELY THIS REGION WILL QUIET DURING THE PERIOD. THERE IS A SLIGHT POSSIBILITY OF A MAJOR FLARE DURING THE NEXT THREE DAYS.

THE GEOMAGNETIC FIELD WAS PREDOMINANTLY UNSETTLED TO ACTIVE. ISOLATED MINOR STORMING WAS ALSO OBSERVED. THE SOURCE OF THIS DISTURBANCE IS UNKNOWN. SOLAR WIND PARAMETERS WERE REASONABLY BENIGN EXCEPT FOR SOME PERIODS OF NEGATIVE BZ AND THE PASSAGE OF A SECTOR BOUNDARY DURING THE PERIOD.

THE GEOMAGNETIC FIELD SHOULD BECOME QUIET TO UNSETTLED FOR THE NEXT THREE DAYS. ISOLATED ACTIVE CONDITIONS COULD BE EXPERIENCED EARLY ON 01 APR AND AGAIN ON 03 APR. THERE IS A POSSIBILITY OF A SOLAR PROTON EVENT DURING THE NEXT THREE DAYS.
