SOLAR ACTIVITY WAS LOW. THE TWO MOST ACTIVE REGIONS WERE 8439 (S24E24) AND 8440 (N19E16). REGION 8439 HAS SHOWN AN INCREASE IN ACTIVITY, PRODUCING 3 C-CLASS EVENTS. THE LARGEST BEING A C5/SF AT 17/1955UT. THIS EVENT ALSO PRODUCED A TYPE II SWEEP. THE REGIONS SPOT COUNT HAS INCREASED FROM 31 TO 40, WITH A SLIGHT REDUCTION IN AREA. CURRENTLY AN FAO SPOT GROUP WITH A BETA MAGNETIC CLASSIFICATION. REGION 8440 HAS SHOWN A REDUCTION IN ACTIVITY PRODUCING ONLY 5 C-CLASS FLARES, THE LARGEST A C4/SF AT 17/1156UT. THE REGIONS SPOT COUNT HAS INCREASED FROM 31 TO 42, WITH A SLIGHT REDUCTION IN AREA. CURRENTLY AN EAI SPOT GROUP WITH A BETA-GAMMA MAGNETIC CLASSIFICATION. ONE NEW REGION WAS NUMBERED TODAY; 8442 (N24W16). CURRENTLY AN 8 SPOT DSO BETA SPOT GROUP.

SOLAR ACTIVITY IS EXPECTED TO BE LOW TO MODERATE. REGIONS 8439 AND 8440 ARE STILL CAPABLE OF PRODUCING ISOLATED M-CLASS EVENTS.

THE GEOMAGNETIC FIELD WAS QUIET. THE GREATER THAN 2 MEV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT WAS AT HIGH LEVELS FOR MOST OF THE DAY WITH THE EXCEPTION OF THE PERIOD BETWEEN 17/0000-0130UT. THE FLUX FELL BELOW THRESHOLD LEVELS DURING THAT PERIOD.

THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO UNSETTLED.
