SOLAR ACTIVITY WAS LOW. THE LARGEST EVENTS OF THE PERIOD WERE A C6/SF FROM REGION 8904 (N23W59), AND A C6/1F FROM REGION 8898 (S13W59). BOTH FLARES EXHIBITED MINOR MULTI-FREQUENCY RADIO BURSTS. REGIONS 8904 AND 8906 (S15E18) PRODUCED SEVERAL SMALLER C-CLASS EVENTS. REGION 8906 REMAINS THE LARGEST REGION ON THE VISIBLE DISK AND NOW EXCEEDS 800 MILLIONTHS OF WHITE LIGHT AREA. A MAGNETIC DELTA CONFIGURATION AND MODERATE TO STRONG GRADIENTS ARE ALSO APPARENT. REMAINING REGIONS WERE STABLE.

SOLAR ACTIVITY IS EXPECTED TO BE MODERATE. REGION 8906 WILL CONTINUE PRODUCING C-CLASS X-RAY ACTIVITY WITH A GOOD CHANCE FOR AN M-CLASS EVENT. MOSTLY C-CLASS ACTIVITY WITH AN ISOLATED CHANCE FOR AN M-CLASS EVENT, EXPECTED FROM REGIONS 8898 AND 8904 AS THEY APPROACH THE WEST LIMB.

THE GEOMAGNETIC FIELD BEGAN THE PERIOD AT QUIET LEVELS BUT WAS UNSETTLED TO ACTIVE SINCE. ISOLATED MINOR STORMING PERIODS WERE ALSO OBSERVED AT HIGH LATITUDES.

THE GEOMAGNETIC FIELD IS EXPECTED TO CONTINUE AT QUIET TO ACTIVE LEVELS. ISOLATED MINOR STORMING PERIODS ARE ALSO POSSIBLE AGAIN, MOSTLY AT HIGH LATITUDES.
