Weekly Bulletin on Solar and Geomagnetic Activity
Highlights on 02 - 08.01.2012,
Forecast on 09 - 16.01.2012,
Carrington Rotations 2118, 2119 (13,61.12.2011; 09,94.01.2012)


SOLAR SUNSPOT ACTIVITY OF THE LAST PERIOD  WAS ON AVERAGE LEVEL. 
ESTIMATED, RATING, WEEKLY AVERAGE OF SUNSPOT NUMBER IN THE INTE-
RNATIONAL SYSTEM  FOR THE PERIOD  WAS MADE W=060+11/-10. ON THE 
VISIBLE DISK OF THE SUN CONSTANTLY ARE PRESENT FROM 5 TO 7 SUN-
SPOT GROUPS, AMONG WHICH ONE AVERAGE SIZE.

 NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY  IS EXPECTED TO BE THE 
AVERAGE. THE CALCULATED MOST LIKELY WEEKLY AVERAGE VALUE OF SUN-
SPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR THE NEXT PERIOD W =
060+10/-10.

FLARE ACTIVITY WAS ON LOW LEVEL IN ALL DAYS. BY DATA OF SOHO CO-
RONOGRAPHS FOR THE PERIOD IT WAS OBSERVED 45 CORONAL MASS EJECTION  
AMONG WHICH WERE ONE TYPE "HALO" (2.01) AND 4 - TYPE "PARTIAL HALO 
II" (angular width 90-180 deg.).

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT VERY 
HIGH LEVEL OF FLUX WAS NOT OBSERVED.

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

ALL PERIOD GEOMAGNETIC CONDITIONS WERE UNSETTLED AND QUIET.

NEXT WEEK GEOMAGNETIC CONDITIONS ARE EXPECTED QUIET AND UNSETTLED.
