SOLAR ACTIVITY WAS MODERATE. A SERIES OF OPTICALLY UNCORRELATED X-RAY EVENTS OCCURRED THROUGH THE PERIOD. THE FIRST WAS A C6 AT 22/2351Z. A LONG DURATION M2 OCCURRED AT 23/0659Z WITH AN ASSOCIATED TYPE II AND TYPE IV RADIO SWEEP. THE TYPE II SHOCK SPEED WAS 850 KM/S. THIS EVENT WAS FOLLOWED SOON AFTER BY AN M1 AT 23/0816Z. POST FLARE LOOPS OBSERVED AT N24E89 SUGGEST NEW REGION NUMBERED TODAY AS 8421 (N29E83) WAS THE LIKELY SOURCE REGION FOR ALL THESE EVENTS. REGION 8421 APPEARS TO BE A LARGE COMPLEX AREA WHICH HAS PRODUCED STRONG SURGING SINCE BECOMING VISIBLE ON THE LIMB. OTHER NEW REGIONS NUMBERED TODAY WERE REGION 8419 (N27E25) AND REGION 8420 (N18E64). TWO DISAPPEARING FILAMENTS WERE REPORTED, ONE BETWEEN 22/2320Z AND 23/1713Z AT N23W23 WHICH WAS 10 DEGREES LONG AND THE OTHER BETWEEN 23/1753-1812Z AT N16E37 WHICH WAS 5 DEGREES LONG.

SOLAR ACTIVITY SHOULD BE LOW TO MODERATE. SEVERAL OF THE REGIONS ON THE DISK ARE CAPABLE OF PRODUCING OCCASIONAL M-CLASS FLARES ESPECIALLY REGION 8421.

THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED.

THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO SLIGHTLY UNSETTLED THROUGH THE FORECAST PERIOD.
