SOLAR ACTIVITY CONTINUED LOW. THOUGH FEW FLARES OCCURRED, A SIGNIFICANT AMOUNT OF NEW FLUX EMERGED, AS EVIDENCED BY FOUR NEW REGIONS THAT WERE NUMBERED. THE REGIONS ARE: 9071 (N22W23), 9072 (N15E16), 9073 (S21E44), AND 9074 (N10E64). THERE ARE 13 REGIONS ON THE DISK, WITH REGION 9070 (N17E29) THE LARGEST AND MOST COMPLEX. THERE WAS A TYPE II SWEEP ASSOCIATED WITH A FILAMENT DISAPPEARANCE FROM REGION 9068 (S19E11) AT 04/2243Z. THAT EVENT WAS DEVOID OF ANY X-RAY ENHANCEMENT, AND DID NOT APPEAR TO SPAWN AN EARTH-DIRECTED CME.

SOLAR ACTIVITY IS EXPECTED TO PERSIST AT THE LOW LEVEL.

THE GEOMAGNETIC FIELD WAS AT QUIET TO ACTIVE LEVELS. THE FEW ACTIVE PERIODS WERE RELATED TO HOUR-LONG INTERVALS OF SOUTHWARD INTERPLANETARY MAGNETIC FIELD ORIENTATION.

THE GEOMAGNETIC FIELD IS EXPECTED TO BE UNSETTLED TO ACTIVE FOR THE NEXT TWO DAYS. EFFECTS OF A HIGH-SPEED SOLAR WIND STREAM ARE DUE, FROM AN EXTENDED NORTH-SOUTH CORONAL HOLE NOW LOCATED MID-WAY IN THE WESTERN SOLAR HEMISPHERE.
