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.
