SOLAR ACTIVITY WAS MODERATE. REGION 8026 (S25E07), A 13 SPOT 'CAO' GROUP, GENERATED A SINGLE M1/1B FLARE AT 01/1348, WHICH WAS PRECEEDED BY THREE C-CLASS EVENTS. THE REGION HAD BEEN SURGING PRIOR TO, BUT HAD STOPPED BEFORE THE ONSET OF THE M1 EVENT. AN ASSOCIATED HIGH SPEED DARK SURGE ACCOMPANIED THE M1 FLARE. ALL FOUR FLARES OCCURRED NEAR THE SMALL OPPOSITE POLARITY FIELD EAST OF THE SOUTHERNMOST PENUMBRA, WHICH SUPPORTS THE MT. WILSON SOLAR OBSERVATORY'S MAGNETIC CLASSIFICATION OF THIS REGION AS A BETA-GAMMA-DELTA. NUMEROUS RADIO BURSTS AT VARIOUS FREQUENCIES WERE OBSERVED BEORE AND AFTER THE FLARE ACTIVITY. IN ADDITION, TWO FILAMENTS DISSAPPEARED OVERNIGHT FROM REGION 8026, WITH THE LARGER OF THE TWO (7 DEGREES) HAVING BECOME HIGHLY ACTIVE PRIOR TO DISAPPEARING.

SOLAR ACTIVITY IS EXPECTED TO BE VERY LOW TO LOW, WITH A CONTINUED CHANCE FOR ISOLATED M-CLASS EVENTS FOR THE NEXT THREE DAYS.

THE GEOMAGNETIC FIELD WAS MOSTLY UNSETTLED FOR THE FIRST HALF OF THE REPORTING PERIOD, WITH A SINGLE PERIOD OF ACTIVE CONDITIONS RECORDED AT FREDRICKSBURG DURING THE INTERVAL 01/0300-0600Z, AND THEN QUIET FOR THE SECOND HALF OF THE DAY. THE GREATER THAN 2 MEV ELECTRONS WERE IN THE MODERATE TO HIGH RANGE.

THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO UNSETTLED FOR THE NEXT THREE DAYS, WITH A CHANCE FOR ISOLATED PERIODS OF ACTIVE CONDITIONS.
