Weekly Bulletin on Solar and Geomagnetic Activity
                  Highlights on 22 - 28.07.2013,
                 Forecast on 29.07 - 04.08.2013,
             Carrington Rotations 2139 (08,42.07.2013)

 SUNSPOT-FORMING ACTIVITY OF THE SUN  REMAINED AT THE AVERAGE LEVEL,
GRADUALLY INCREASING. WEEKLY,  THE AVERAGE OF SUNSPOT NUMBER IN THE 
INTERNATIONAL SYSTEM  WAS MADE W = 040+10/-8.  ON THE VISIBLE SOLAR 
DISK CONSTANTLY THERE WERE 3 - 5 QUITE SUNSPOTS GROUPS. 

NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY IS EXPECTED TO BE THE AVE-
RAGE LEVEL.  THE CALCULATED  MOST  LIKELY WEEKLY AVERAGE VALUE OF 
SUNSPOT NUMBER  IN THE INTERNATIONAL SYSTEM  FOR THE NEXT WEEK IS 
EXPECTED W = 050+10/-10.

 FLARE ACTIVITY  WAS AT THE LOW LEVEL. BY SOHO AND STEREO CORONO-
GRAPHS DATA THERE  WERE OBSERVED 24 CME  FROM WHICH ONE WAS THE 
TYPE " HALO" AND ONE - "PARTIAL HALO II" TYPE.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT VERY HIGH 
LEVEL BEGAN AT 11/01 UT AND OBSERVED TO 25 AND 27. 

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

 MINOR GEOMAGNETIC STORM (G0, Ams = 27, dur.= 12 h.) WAS REGISTERED 25
-27 JULY ACCORDING BY DATA OF THE CENTER IN BOULDER. ACCORDING IZMIRAN 
DATA IN THIS DAY WAS REGISTERED SUBSTORM (9 h.) INTENSITE G0. IN OTHER 
DAYS GEOMAGNETIC CONDITION WAS UNSETTLED AND QUITE.

NEXT WEEK THE GEOMAGNETIC SITUATION IS EXPECTED UNSETTLED AND QUITE.
