SOLAR ACTIVITY WAS LOW. REGION 8293 (S23W58) PRODUCED C1 SUBFLARES AT 12/1159Z AND AGAIN AT 12/1759Z. THIS REGION'S MAGNETIC CONFIGURATION SIMPLIFIED SLIGHTLY AND OVERALL DECAY WAS OBVIOUS IN BOTH WHITE LIGHT AND H-ALPHA. REGION 8299 (N16E14) IS THE LARGEST REGION ON THE VISIBLE DISK COVERING 520 MILLIONTHS OF WHITE LIGHT AREA. IT PRODUCED SEVERAL PLAGE ENHANCEMENTS IN THE PAST 24 HOURS BUT NO FLARES WERE OBSERVED. NO OTHER SIGNIFICANT ACTIVITY WAS NOTED. NEW REGION 8302 (S14E30) WAS NUMBERED TODAY.

SOLAR ACTIVITY IS EXPECTED TO BE LOW. REGION 8293, THOUGH DECAYING, IS STILL QUITE ACTIVE AND CAPABLE OF MORE C-CLASS ACTIVITY. REGION 8299 IS ALSO LIKELY TO PRODUCE OCCASIONAL C-CLASS FLARES. BOTH REGIONS HAVE A SLIGHT CHANCE OF AN M-CLASS.

THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. ISOLATED ACTIVE CONDITIONS WERE EXPERIENCED AT HIGH LATITUDES DURING NIGHT TIME HOURS.

THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO UNSETTLED WITH ISOLATED ACTIVE PERIODS MOSTLY AT HIGH LATITUDES.
