Weekly Bulletin on Solar and Geomagnetic Activity
Highlights on 08 - 14.08.2011,
Forecast on 15 - 22.08.2011 ,
Carrington Rotation 2113 (30,22.07.2011)

SOLAR SUNSPOT ACTIVITY OF THE LAST PERIOD CHANGED FROM THE AVERAGE
LEVEL TO ZERRO ACTIVITY. ESTIMATED, RATING, WEEKLY AVERAGE OF SUN-
SPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR THE PERIOD WAS MADE
W=023+25/-23. ON THE VISIBLE DISK OF THE SUN CONSTANTLY WAS PRESENT
FROM 3 TO 2 SUNSPOT GROUPS AND TO 14 AUGUST THERE ARE NO SUNSPOT GROUPS.

NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY IS EXPECTED TO BE THE LOW
AND VERY LOW. THE CALCULATED MOST LIKELY WEEKLY AVERAGE VALUE OF SUNSPOT
NUMBER IN THE INTERNATIONAL SYSTEM FOR THE NEXT PERIOD W=025+10/-10.

FLARE ACTIVITY WAS AT HIGH LEVEL ON AUGUST, 9 WHEN IN SUNSPOT GROUP
AR11263 (N18L302, Sp=720 m.v.h) WERE OCCURENCED MOSTLY POWER FLARES
IN THE CURRENT SOLAR CYCLE: X-RAY CLASS X6.9, AT THE AVERAGE LEVEL -
ON AUGUST, 8, OTHER DAYS - ON A LOW LEVEL. SOHO CORONOGRAPH HAVE
REGISTRED 53 CME FROM WHICH 4 WERE TYPE PARTIAL HALO II AND ONE HALO
TYPEII FROM THE LARGE FLARE ON AUGUST, 9th.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT VERY HIGH LEVEL
OF FLUX WAS OBSERVED AUGUST, 8 - 13.

NEXT WEEK THE GREATER THAN 2 MeV ELECTRON FLUX AT HIGH LEVEL IS EXPECTED 16 -
22 AUGUST.

ALL PERIOD GEOMAGNETIC CONDITIONS WERE UNSETTLED AND QUIET.

NEXT WEEK IT IS MOST PROBABLE QUIET AND UNSETTLED GEOMAGNETIC CONDITIONS.
