SOLAR ACTIVITY WAS LOW. REGIONS 8224 (S24W90) AND 8226 (N18W66) PRODUCED SEVERAL C-CLASS FLARES INCLUDING A C7 LONG DURATION EVENT AT 27/1335Z WITH MODERATE RADIO BURSTS. BOTH REGIONS HAD A FLARE IN PROGRESS DURING THE X-RAY EVENT. LASCO IMAGERY SHOWS A LARGE CORONAL MASS EJECTION ORIGINATING FROM THE NW. WELL DEFINED POST FLARE LOOPS ARE OBVIOUS ON THE EIT IMAGES SUGGESTING THAT REGION 8226 WAS THE PROBABLE SOURCE FOR THE LONG DURATION EVENT. A MODERATE 8 FREQUENCY RADIO BURST AND TENFLARE ALSO OCCURRED WITH THIS EVENT. REGION 8224 WAS SPOTLESS FOR MOST OF ITS TRANSIT ON THE VISIBLE DISK BEFORE DEVELOPING RAPIDLY EARLY YESTERDAY. SPOTS ARE NOW VISIBLE IN THIS REGION AS IT ROUNDS THE WEST LIMB. REMAINING REGIONS HAVE BEEN QUIET.

SOLAR ACTIVITY IS EXPECTED TO BE LOW TO MODERATE. DRAMATIC GROWTH IN REGION 8224 WILL LIKELY ENSURE CONTINUED C-CLASS ACTIVITY AND A DEVELOPING CHANCE FOR M-CLASS. REGION 8226 WILL ALSO CONTINUE PRODUCING C-CLASS WITH A CHANCE OF A M-CLASS FLARE.

THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED.

THE GEOMAGNETIC FIELD IS EXPECTED TO REMAIN MOSTLY QUIET TO UNSETTLED. WE ARE EXPECTING MINOR GEOEFFECTIVNESS ON DAY 3 FROM TODAY'S LONG DURATION EVENT.
