SOLAR ACTIVITY REMAINED LOW. A VERY LONG DURATION C5 X-RAY EVENT WAS OBSERVED FROM 25/1231-1434Z (HALF POWER). HOWEVER, X-RAY FLUXES FROM THIS EVENT DID NOT RETURN TO BACKGROUND UNTIL THE END OF THE PERIOD. A LARGE FAST CORONAL MASS EJECTION WAS OBSERVED IN THE SOUTHWEST QUADRANT WITH THIS EVENT AND RECENT X-RAY IMAGERY SHOW THIS FLARE ORIGINATING FROM BEHIND THE SOUTHWEST LIMB. THE SOURCE REGIONS THERE ARE 2-3 DAYS BEHIND THE LIMB. REGION 8185 (S25E25) SHOWED SLIGHT DECAY AND PRODUCED SEVERAL SUBFLARES. THIS REGION REMAINED MAGNETICALLY COMPLEX. A SMALL FILAMENT FADED IN THIS REGION BETWEEN 25/0112-1320Z. REGION 8183 (N22W32) CEASED ITS RAPID GROWTH PHASE AND BEGAN TO DECAY. AN OPTICALLY UNCORRELATED WEAK TYPE IV WAS OBSERVED AT 24/2207Z.

SOLAR ACTIVITY SHOULD BE PREDOMINANTLY LOW FOR THE NEXT THREE DAYS. REGION 8185 IS BECOMING LESS A THREAT FOR M-CLASS FLARES.

THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED FROM 24/2100Z-25/0900Z. UNSETTLED TO ACTIVE CONDITIONS WERE OBSERVED FOR THE REMAINDER OF THE PERIOD. IT IS LIKELY THIS SMALL DISTURBANCE IS FROM AN OBLIQUE IMPACT OF ONE OF THE MANY CORONAL MASS EJECTIONS OBSERVED DURING THE LAST WEEK.

THE GEOMAGNETIC FIELD SHOULD BE UNSETTLED TO ACTIVE ON 26 MAR. ISOLATED MINOR STORM PERIODS ARE POSSIBLE DURING THIS TIME. QUIET TO UNSETTLED CONDITIONS ARE FORECAST FOR 27-28 MAR.
