SOLAR ACTIVITY WAS LOW. REGION 8065 (N18W56) HAS CONTINUED TO GROW AND SHOWS THE FORMATION OF SOME MAGNETIC COMPLEXITY, PARTICULARLY IN THE TRAILING PORTION OF THE GROUP WHERE A GAMMA (AND POTENTIALLY A DELTA) CONFIGURATION HAS FORMED. THE INVERSION LINE RUNS IN A MOSTLY EAST-WEST DIRECTION AND IS A GOOD CANDIDATE FOR DEVELOPING SHEAR. THE GROUP PRODUCED NUMEROUS LOW LEVEL C-FLARES TODAY. THE MOST NOTABLE OF THESE WAS A LONG DURATION C4/SN THAT BEGAN AT ABOUT 2015Z, ROSE SLOWLY TO MAXIMUM AT 2035Z, AND WAS DECAYING SLOWLY AT FORECAST ISSUE TIME. THIS EVENT WAS ACCOMPANIED BY STRONG RADIO BURSTS (1600 SFU AT 2695 MHZ), AND TYPE II/IV RADIO SWEEPS. THE TYPE II SHOCK SPEED WAS ESTIMATED TO BE AROUND 900 KM/S. THERE ARE THREE OTHER SPOTTED REGIONS ON THE DISK INCLUDING NEW REGION 8066 (N22E73), BUT THESE REGIONS WERE RELATIVELY CALM COMPARED TO 8065.

SOLAR ACTIVITY IS EXPECTED TO BE MOSLY LOW. THERE IS A CHANCE FOR AN ISOLATED M-CLASS FLARE FROM REGION 8065 OVER THE NEXT THREE DAYS.

THE GEOMAGNETIC FIELD WAS PREDOMINANTLY QUIET. THERE WERE OCCASIONAL UNSETTLED PERIODS, PARTICULARLY AT THE HIGH LATITUDES.

THE GEOMAGNETIC FIELD IS EXPECTED TO BE QUIET TO UNSETTLED FOR THE NEXT THREE DAYS. THERE IS A POSSIBILITY FOR ENHANCED ACTIVITY BEGINNING LATE ON THE THIRD DAY IN RESPONSE TO A CORONAL HOLE THAT WILL BE ROTATING INTO A GEOEFFECTIVE POSITION AT THAT TIME.
