SOLAR ACTIVITY WAS MODERATE DUE TO TWO M-CLASS EVENTS DURING THE PERIOD. THE FIRST WAS AN OPTICALLY UNCORRELATED M1 X-RAY FLARE AT 23/0030UT AND THE SECOND WAS AN M2/SF FROM REGION 8910 AT 23/1214UT. REGION 8910 IS THE LARGEST AND MOST ACTIVE REGION AND CAN BE EXPECTED TO CONTINUE TO PRODUCE C AND POSSIBLE M-CLASS EVENTS AS IT APPROACHES THE WEST LIMB. REGIONS 8913 (S06W50), 8915 (N23W14), AND 8917 (N19W47) ALL PRODUCED C-CLASS FLARES DURING THE PERIOD. REGIONS 8916 (N13E01), 8918 (N13W66), AND 8921 (S15E37) WERE ALSO ACTIVE, PRODUCING OPTICAL SUBFLARES DURING THE REPORTING PERIOD. FOUR NEW REGIONS WERE NUMBERED; 8924 (N13E70), 8925 (S17E76), 8926 (S10W18), AND 8927 (N18E01).

SOLAR ACTIVITY IS EXPECTED TO BE MODERATE.

THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE. THE SOLAR WIND SPEED REMAINED HIGH, ALTHOUGH SHOWING A SLIGHT DECREASE DURING THE PERIOD, FROM 600 TO 500 KM/S. PRESUMABLY RELATED TO A WELL POSITIONED CORONAL HOLE IN THE SOUTHWEST.

THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO ACTIVE, WITH ISOLATED MINOR STORMING CONDITIONS POSSIBLE AT HIGHER LATITUDES DURING THE SECOND DAY OF THE PERIOD.
