SOLAR ACTIVITY WAS VERY LOW. TWO NEW REGIONS ROTATED INTO VIEW, 8178 (S15E72) AND 8179 (S22E60), MAKING A TOTAL OF 5 SPOTTED REGIONS NOW VISIBLE. REGION 8179 IS THE LIKELY RETURN OF OLD 8156, THE PRODUCER OF MANY C-CLASS FLARES LAST ROTATION. A LARGE BUSHY FILAMENT POSITIONED NEAR S50E10 DISAPPEARED EARLY IN THE PERIOD.

SOLAR ACTIVITY IS EXPECTED TO BE VERY LOW TO LOW. IIA. GEOPHYSICAL ACTIVITY SUMMARY FROM 09/2100Z TO 10/2100Z: THE GEOMAGNETIC FIELD WAS QUIET UNTIL 0600Z. ACTIVE TO MAJOR STORM CONDITIONS HAVE PREVAILED SINCE. SOLAR WIND DATA SHOW A STEADY INCREASE IN SPEED STARTING NEAR 0600Z AND CONTINUING TO A MAXIMUM VALUE NEAR 500 KM/S AT THE END OF THE PERIOD. OTHER SOLAR WIND DATA SUGGEST THE POSSIBLE SOURCE OF THE ACTIVITY TO BE A HIGH SPEED STREAM ORIGINATING FROM THE SOLAR SOUTHWEST QUADRANT, ALTHOUGH AN EXACT DETERMINATION IS ELUSIVE AT THIS POINT. THE ENHANCED TOTAL FIELD IN THE SOLAR WIND ARGUES FOR A CONTRIBUTION FROM A CME AS WELL.

THE GEOMAGNETIC FIELD IS EXPECTED TO PERSIST AT ACTIVE TO MINOR STORM LEVELS FOR THE MAJORITY OF THE NEXT 24 HOURS. THE DISTURBANCE SHOULD THEN WEAKEN WITH TIME, GIVING WAY TO QUIET TO UNSETTLED CONDITIONS BY THE END OF THE INTERVAL.
