Weekly Bulletin on Solar and Geomagnetic Activity
               Highlights on 03 - 10.02.2013,
                 Forecast on 11 - 18.02.2013,
           Carrington Rotations 2133 (25,84.01.2013)

SUNSPOT-FORMING ACTIVITY OF THE SUN REMAINED AT THE LOW AND AVERAGE LE-
VEL. WEEKLY, THE AVERAGE OF SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM  
FOR THE PERIOD (8 DAY) WAS MADE W=031+16/-13. ON THE VISIBLE SOLAR DISK 
CONSTANTLY THERE WERE PRESENT 2 - 4 SMALLAND QUITE 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 SUNSPOT 
NUMBER IN THE INTERNATIONAL SYSTEM  FOR THE NEXT WEEK IS EXPECTED  W = 
040+10/-10.

FLARE ACTIVITY WAS AT LOW LEVEL 3-6.02 AND VERY LOW LEVEL ON THE OTHER 
DAYS. BY SOHO AND STEREO CORONOGRAPHS DATA THERE WERE OBSERVED 34 CME 
AND TWO OF THEM WERE THE "PARTIAL HALO II" TYPE.
