Weekly Bulletin on Solar and Geomagnetic Activity
               Highlights on 03 - 09.12.2012,
                Forecast on 10 - 17.12.2012,
         Carrington Rotations 2131 (02,17.12.2012)

 SUNSPOT-FORMING ACTIVITY OF THE SUN WAS REMAINED ON THE LOW AND 4 - 5
NOVEMBER - THE AVERAGE LEVELS.  WEEKLY,  THE AVERAGE OF SUNSPOT NUMBER 
IN THE INTERNATIONAL SYSTEM FOR THE PERIOD WAS MADE W = 028+19/-14. ON 
THE VISIBLE SOLAR DISK CONSTANTLY THERE WERE PRESENT 2-6 SMAL SUNSPOTS 
GROUPS.

NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY IS EXPECTED TO BE THE LOW  AND 
LOW LEVELS. THE CALCULATED MOST LIKELY WEEKLY AVERAGE VALUE OF SUNSPOT 
NUMBER IN THE INTERNATIONAL SYSTEM FOR THE NEXT WEEK IS EXPECTED W = 
040+10/-20.

FLARE ACTIVITY WAS AT THE LOW LEVEL ON DECEMBER 3, 5, 7 AND 9, AND THE 
VERY LOW LEVEL IN OTHER DAYS. BY SOHO AND STEREO CORONOGRAPHS DATA THE-
RE WERE OBSERVED 11 CME ON 5.12 THREE OF WHICH WAS THE "PARTIAL HALO II".
