SOLAR ACTIVITY WAS MODERATE. THREE M-CLASS EVENTS OCCURRED OVER THE LAST 24 HOURS: AN M3 AT 0204Z (WITH TYPE II/IV SWEEPS), AND M1 AT 0608Z (WITH TYPE II/IV), AND AN M1 AT 1415Z. NO H-ALPHA FLARES WERE OBSERVED WITH THESE X-RAY EVENTS, BUT SUPPLEMENTAL DATA (EIT AND LASCO) INDICATE THAT REGION 8210, WHICH HAS ROTATED AROUND WEST LIMB, WAS THE MOST LIKELY SOURCE. REGION 8214 (N28W61) WAS ABLE TO MUSTER A C5/1N FLARE AT 1306Z. THE REGION APPEARS TO BE DECAYING AND SIMPLIFYING, ALTHOUGH THE PROXIMITY TO THE LIMB MAKES ANALYSIS MORE DIFFICULT. A NEW B-TYPE GROUP NEAR N26E53 WAS ASSIGNED TODAY AS 8219. REGION 8218 (S20E48) APPEARS TO BE GROWING, BUT WAS FAIRLY STABLE. X-RAY IMAGES INDICATE THAT THERE IS A REGION BEHIND THE NORTHEAST LIMB WHICH SHOULD ROTATE INTO VIEW SOMETIME IN THE NEXT FEW DAYS.

SOLAR ACTIVITY IS EXPECTED TO BE MODERATE. THERE IS A FAIR CHANCE FOR AN ISOLATED M-CLASS EVENT FROM EITHER REGION 8214 OR 8218.

THE GEOMAGNETIC FIELD WAS PREDOMINANTLY ACTIVE DURING THE PAST 24 HOURS. THERE WERE SOME PERIODS OF MINOR STORM LEVELS AT HIGH LATITUDES, PARTICULARLY AROUND 07/2100-08/0200Z AND FROM 08/1500-08/1700Z.THE DISTURBANCE BEGAN GRADUALLY: THERE WAS NO CLEAR INDICATOR OF THE ARRIVAL OF A SHOCK AT L1 OR EARTH. THE GREATER THAN 2 MEV ELECTRON FLUXES WERE AT MODERATE TO HIGH LEVELS DURING THE DAY.

THE GEOMAGNETIC FIELD IS EXPECTED TO BE UNSETTLED TO ACTIVE FOR THE NEXT 24 HOURS. PERSISTENCE FROM THE CURRENT DISTURBANCE MAY CAUSE SOME LOCAL NIGHTTIME SUBSTORM EFFECTS. PREDOMINANTLY UNSETTLED LEVELS ARE EXPECTED FOR THE SECOND AND THIRD DAYS.
