SOLAR ACTIVITY WAS LOW. ONLY TWO LOW C-CLASS EVENTS OCCURRED - AN OPTICALLY UNCORRELATED C1 FLARE AT 05/0433Z AND A C1/SF AT 05/0140Z FROM DEVELOPING REGION 9110 (S19W07). MINOR GROWTH WAS ALSO OBSERVED IN REGIONS 9114 (N12E41) AND 9115 (N16E56), BOTH PRODUCING OCCASIONAL SMALL FLARES AND BRIGHTENINGS. NEW REGIONS 9117 (S09W07), 9118 (N18W02), AND 9119 (S13E08) WERE NUMBERED TODAY.

SOLAR ACTIVITY IS EXPECTED TO REMAIN LOW. OCCASIONAL LOW C-CLASS FLARES ARE EXPECTED. IIA. GEOPHYSICAL ACTIVITY SUMMARY 04/2100Z TO 05/2100Z: THE GEOMAGNETIC FIELD WAS AT QUIET TO MAJOR STORM LEVELS. A SINGLE PERIOD OF MAJOR STORMING, MOSTLY AT HIGH LATITUDES, OCCURRED BETWEEN 05/06 - 09Z. THE PERIOD BEGAN WITH QUIET TO UNSETTLED CONDITIONS, BUT BY 05/06Z, SOLAR WIND SPEED BEGAN TO INCREASE, REACHING 600KM/S BY AROUND 05/10Z. BZ SUSTAINED EXTENDED PERIODS OF NEAR -10NT. AT THIS POINT IT IS DIFFICULT TO SAY FOR CERTAIN THE ORIGIN OF THE DISTURBANCE, BUT IT MAY BE FROM HIGH-SPEED CORONAL HOLE FLOW, PRECEDED BY A SUBSTANTIAL CO-ROTATING INTERACTION REGION.

THE GEOMAGNETIC FIELD IS EXPECTED TO BE AT QUIET TO ACTIVE LEVELS THROUGH DAY ONE WHILE THE PRESENT DISTURBANCE SUBSIDES. ISOLATED MINOR STORM PERIODS AT HIGH LATITUDES ARE LIKELY. QUIET TO UNSETTLED CONDITIONS SHOULD PREVAIL THROUGH DAYS TWO AND THREE.
