HAPPY NEW YEAR FOR ALL USERS

      Weekly Bulletin on Solar and Geomagnetic Activity
               Highlights on 24 - 30.12.2012,
                Forecast on 31.12.2012 -05.01.2013,
   Carrington Rotations 2131, 2132 (02,17; 29,50.12.2012) 

SUNSPOT-FORMING ACTIVITY OF THE SUN AT THE LAST TWO DAYS WERE ON THE 
LOW AND OTHER DAYS - THE AVERAGE LEVELS.  WEEKLY, THE AVERAGE OF SUN-
SPOT  NUMBER  IN THE INTERNATIONAL SYSTEM  FOR THE PERIOD  WAS  MADE 
W=035+14/-12. ON THE VISIBLE SOLAR DISK CONSTANTLY THERE WERE PRESENT 
5 - 2 SMALL SUNSPOTS GROUPS.

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

FLARE ACTIVITY WAS AT A LOW LEVEL ALL DAYS, EXCEPT DECEMBER 28 AND 
30. BY SOHO AND STEREO CORONOGRAPHS DATA THERE WERE OBSERVED 47 CME 
TWO OF WHICH WAS THE "PARTIAL HALO II".
