Weekly Bulletin on Solar and Geomagnetic Activity
       Highlights on 18 - 24.06.2012,
        Forecast on 25.06 - 02.07.2012,
Carrington Rotations 2124 2125 (25,42.05; 21,62.06.2012)
 
SUNSPOT ACTIVITY WAS ON THE AVERAGE LEVEL, BUT AFTER 20.06 - ON THE
LOW. WEEKLY, THE AVERAGE OF SUNSPOT NUMBER IN THE INTERNATIONAL SYS-
TEM FOR THE PERIOD WAS MADE W=019+21/-5. ON THE VISIBLE DISK OF THE 
SUN CONSTANTLY WERE PRESENT FROM 5 TO 1 SUNSPOT GROUP ONE OF WHICH 
SINCE WAS BIG, BUT JUNE 21 IT WENT FOR WEST LIMB.

NEXT WEEK  THE LEVEL OF SUNSPOT ACTIVITY  IS EXPECTED TO BE LOW AND 
AVERAGE. THE CALCULATED MOST LIKELY WEEKLY AVERAGE VALUE OF SUNSPOT 
NUMBER IN THE INTERNATIONAL SYSTEM FOR THE NEXT WEEK W=040+15/-15.

FLARE ACTIVITY WAS AT LOW LEVEL 18 - 20 AND 23.06.  IN OTHER DAYS - 
AT VERY LOW LEVEL. BY DATA OF SOHO AND STEREO CORONOGRAPHS FOR THE 
PERIOD IT WAS OBSERVED 23 CME.
