SOLAR ACTIVITY WAS LOW. SEVERAL C-CLASS FLARES OCCURRED FROM A VARIETY OF SUNSPOT GROUPS, INCLUDING 8392 (S22W46), 8395 (N22E11), AND 8396 (N28W95). REGION 8395 HAS CHANGED LITTLE SINCE YESTERDAY. THE SUNSPOTS LEADING THIS GROUP HAVE BEEN SPLIT OFF AS A SEPARATE BIPOLAR REGION AND NUMBERED 8398 (N18W05). THE SUNSPOTS TO THE NORTHEAST HAVE ALSO BEEN SPLIT OFF AS A SEPARATE GROUP AND NUMBERED 8399 (N30E23). THE REMAINING SPOTS STILL LEAVE 8395 AS A MODERATELY LARGE F-TYPE GROUP SPANNING OVER 20 DEGREES IN EXTENT. EMERGING REGIONS 8400 (S18E08) AND 8401 (N12E27) WERE ALSO NUMBERED. ADDITIONAL SUNSPOTS ARE ROTATING AROUND THE EAST LIMB BEHIND REGION 8397 (N15E64). PRELIMINARY ANALYSIS SUGGESTS THAT THESE COMPRISE A SEPARATE GROUP AND WILL MOST LIKELY BE NUMBERED AFTER A PROPER SEPARATION IS DETERMINED.

SOLAR ACTIVITY IS EXPECTED TO BE LOW TO MODERATE. C-CLASS ACTIVITY IS EXPECTED AND MODERATE ACTIVITY IS POSSIBLE IN A NUMBER OF SUNSPOT GROUPS. REGIONS 8395, 8396, AND 8397 ARE EXPECTED TO BE THE PRIMARY FLARE PRODUCERS.

THE GEOMAGNETIC FIELD RANGED FROM QUIET TO ACTIVE. A WEAK SUDDEN IMPULSE WAS OBSERVED ON GROUND MAGNETOMETERS AT ABOUT 30/0512Z. ACE DID NOT SEE A STRONG SHOCK; HOWEVER, IT DID INDICATE A CHANGE IN THE SOLAR WIND STRUCTURE AT ABOUT 30/0430Z. THIS MAY BE RELATED TO THE CME DETECTED BY SOHO/LASCO ON 27 NOVEMBER.

THE GEOMAGNETIC FIELD IS EXPECTED TO BE MOSTLY QUIET TO UNSETTLED WITH THE POSSIBILITY OF ISOLATED ACTIVE PERIODS.
