SDF Number 235 Issued at 2200Z on 23 AUG 1997

IA. Analysis of Solar Active Regions and Activity from 22-2100Z to 23-2100Z

SOLAR ACTIVITY WAS VERY LOW. A LONG DURATION B3 X-RAY EVENT WAS RECORDED AT AN UNSPECIFIED LOCATION DURING THE INTERVAL 23/1413-1456Z. REGION 8073 (N13W85), THE ONLY ACTIVE REGION ON THE VISIBLE DISK, IS QUIETLY ROTATING AROUND THE WEST LIMB AS A SINGLE SPOT 'AXX' GROUP. OLD REGION 8069 APPEARS TO BE RETURNING AROUND THE EAST LIMB, WITH IT'S CURRENT CHARACTERISTICS AND INTENSITY AS YET UNDEFINED.
IB. Solar Activity Forecast
SOLAR ACTIVITY IS EXPECTED TO BE VERY LOW. IIA. GEOPHYSICAL ACTIVITY SUMMARY FROM 22/2100Z TO 23/2100Z: THE GEOMAGNETIC FIELD HAS BEEN QUIET AT ALL LATITUDES FOR THE PAST 24 HOURS.
IIB. Geophysical Activity Forecast
THE GEOMAGNETIC FIELD IS EXPECTED TO BE MOSTLY QUIET FOR THE NEXT THREE DAYS, WITH THE CHANCE FOR ISOLATED PERIODS OF UNSETTLED CONDITIONS.
