SOLAR ACTIVITY HAS BEEN LOW FOR THE PAST 24 HOURS. REGION 8882 (S15W83) PRODUCED TODAY'S LARGEST EVENT, A C6/SF AT 03/2345Z. TWO NEW SUNSPOT GROUPS EMERGED: REGION 8899 (S11E19) AND REGION 8900 (S15E16). REGION 8900 SHOWED STEADY GROWTH AND PRODUCED OCCASIONAL SUBFLARES. THE GROUP DEVELOPED INTO A SMALL, D-TYPE REGION BY THE END OF THE REPORTING PERIOD. REGION 8891 (S15W29) IS STILL THE LARGEST GROUP ON THE DISK BUT SHOWED SIGNS OF DECAY AND WEAKENING MAGNETIC FIELDS. AN 11 DEGREE FILAMENT NEAR N40W36 DISAPPEARED BETWEEN 0804-0900Z. X-RAY IMAGES FROM THE YOHKOH SPACECRAFT SHOWED AN ENHANCED LOOP SYSTEM FORMED IN ASSOCIATION WITH THE DISAPPEARANCE, SUGGESTING THAT A CME OCCURRED. ANOTHER 15 DEGREE FILAMENT NEAR S35E50 DISAPPEARED AT ABOUT 1800Z. THIS DISAPPEARANCE WAS FOLLOWED BY PARALLEL H-ALPHA RIBBONS, A WEAK X-RAY ENHANCEMENT, A WEAK TYPE II SWEEP, AND A FAINT CME SIGNATURE AS OBSERVED BY THE MAUNA LOA CORONAGRAPH, ALL OF WHICH INDICATE ERUPTION OF THE FILAMENT.

SOLAR ACTIVITY IS EXPECTED TO BE LOW TO MODERATE. A GRADUAL DOWNWARD TREND IN ACTIVITY IS EXPECTED WITH THE DEPARTURE OF REGIONS 8886 AND 8882 OVER THE NEXT THREE DAYS. THERE REMAINS A SLIGHT CHANCE FOR A MAJOR FLARE EVENT. REGION 8891 CONTINUES TO BE THE MAIN THREAT FOR AN ISOLATED MAJOR EVENT.

THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. SOLAR WIND OBSERVATIONS AT THE L1 POINT GAVE NO INDICATION OF RECENT FLARE-ASSOCIATED CORONAL MASS EJECTION ACTIVITY.

THE GEOMAGNETIC FIELD IS EXPECTED TO BE UNSETTLED TOMORROW, WITH A POSSIBILITY FOR SOME ACTIVE PERIODS. PREDOMINANTLY UNSETTLED LEVELS SHOULD FOLLOW ON THE SECOND DAY, AND CONDITIONS SHOULD BE QUIET TO UNSETTLED ON THE THIRD DAY. THERE IS A SLIGHT, BUT DECREASING POSSIBILITY THAT A GLANCING BLOW FROM CME ACTIVITY OF 2 MARCH WILL BE SEEN OVER THE NEXT 24 HOURS.
