Weekly Bulletin on Solar and Geomagnetic Activity
       Highlights on 06 - 12.08.2012,
        Forecast on 13 - 20.08.2012,
Carrington Rotations 2126, 2127 (18,82.07; 15,04.08.2012)

SUNSPOT ACTIVITY OF THE SUN REMAINED AT THE AVERAGE LEVEL. WEEKLY, 
THE AVERAGE OF SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR THE 
PERIOD WAS MADE W=061+13/-15. ON THE VISIBLE SOLAR DISK CONSTANTLY 
THERE WERE 6-8 THE SMALL SUNSPOT GROUPS. 

NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY IS EXPECTED TO BE LOW AND AVE-
RAGE. THE CALCULATED MOST LIKELY WEEKLY AVERAGE VALUE OF SUNSPOT NUM-
BER  IN THE INTERNATIONAL SYSTEM  FOR THE NEXT WEEK  IS  EXPECTED W = 
060+10/-10.

FLARE ACTIVITY WAS ON THE AVERAGE LEVEL AT 6 AND 11 AUGUST, AND THE 
LOW IN OTHER DAYS. BY DATA OF SOHO AND STEREO CORONOGRAPHS  FOR THE 
PERIOD IT WAS OBSERVED 47 CME - ONE WAS TYPE "PARTIAL HALO III" .

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT VERY HIGH 
LEVEL IS NOT EXPECTED.

GEOMAGNETIC ACTIVITY WAS ACTIVE ON AUGUST 8 WHEN EARTH PASSED DOUBLE 
SECTOR BOUNDARY. IN OTHER DAYS THE GEOMAGNETIC SITUATION REMAINED UN-
SETTLED AND QUIET.
   
NEXT WEEK THE GEOMAGNETIC SITUATION IS EXPECTED UNSETTLED AND QUITE.
