SOLAR ACTIVITY INCREASED TO MODERATE. AN UNOBSERVED M3 X-RAY FLARE OCCURRED AT 0317Z. TYPE II SWEEP AND MODERATE DISCRETE RADIO BURSTS ACCOMPANIED THE EVENT. FREQUENT LOW-LEVEL C-CLASS FLARES FROM REGIONS 8293 (S22W05) AND 8299 (N16E64) WERE COMMONPLACE DURING THE PERIOD. BOTH OF THESE REGIONS ARE IMPRESSIVE IN WHITE LIGHT AND H-ALPHA, AND SHOW NO SIGNS OF ABATING THEIR FLARE ACTIVITY. IN THE EARLY HOURS OF 08 AUGUST, A VERY PROMINENT, CENTRALLY-LOCATED FILAMENT MEASURING APPROXIMATELY 30 DEGREES DISAPPEARED. THIS FEATURE WAS ORIENTED NORTH-SOUTH AND CENTERED NEAR N30E00. IT IS LIKELY THAT THIS WAS A SYMPTOM OF A MASS EJECTION HIGHER IN THE CORONA. ELSEWHERE, THE REMAINING FOUR SPOTTED REGIONS EXHIBITED LITTLE ACTIVITY, AND THE LIMBS WERE QUIET.

SOLAR ACTIVITY IS EXPECTED TO BE LOW TO MODERATE. REGIONS 8293 AND 8299 ARE BOTH GOOD CANDIDATES FOR CONTINUED OCCASIONAL M-CLASS EVENTS.

THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE. SHORT-LIVED SUBSTORMS OCCURRED DURING LOCAL NIGHTTIME HOURS.

THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO UNSETTLED THE NEXT 72 HOURS. TODAY'S DSF/CME EVENT IS NOT EXPECTED TO AFFECT THE FIELD BEFORE 12 AUGUST.
