Weekly Bulletin on Solar and Geomagnetic Activity
                Highlights on 09 - 15.09.2013,
                 Forecast on 16 - 23.09.2013,
           Carrington Rotation 2041 (31,87.08.2013)

 SUNSPOT-FORMING ACTIVITY OF THE SUN CHANGED AT THE AVERAGE TO THE 
LOW LEVEL. WEEKLY, THE AVERAGE OF SUNSPOT NUMBER IN THE INTERNATI-
ONAL SYSTEM WAS MADE W=019+16/-12. ON THE VISIBLE SOLAR DISK CONS-
TANTLY THERE WERE 5 - 1 QUITE SMALL SUNSPOT GROUPS.

NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY IS EXPECTED TO BE THE LOW 
AND AVERAGE LEVEL. THE CALCULATED MOST LIKELY WEEKLY AVERAGE VALUE 
OF SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR THE NEXT WEEK IS 
EXPECTED W = 030+20/-20.

 FLARE ACTIVITY WAS FOR AT A VERY LOW LEVEL. DURING THE CONSIDERED 
PERIOD 7 DSF  WERE OBSERVED.  BY SOHO AND STEREO CORONOGRAPHS DATA  
THERE WERE OBSERVED 28  CME FROM WHICH THREE WERE THE "PARTIAL HALO 
II" TYPE.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT VERY HIGH 
LEVEL BEGAN 02.09/1315 UT AND WERE OBSERVED ON SEPTEMBER 09-10.

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

 THE GEOMAGNETIC SITUATION CHANGED FROM UNSETTLED TO QUITE ALL PERIOD. 

NEXT WEEK THE GEOMAGNETIC CONDITION IS EXPECTED QUIET  AND  UNSETTLED.
