      Weekly Bulletin on Solar and Geomagnetic Activity
               Highlights on 28.04 - 4.05.2014,
                 Forecast on 5 - 12.05.2014,
    Carrington Rotation 2149,2150 (7,36.04; 04,62.05.2014)

 SUNSPOT-FORMING ACTIVITY OF THE SUN REMAINED ON THE AVERAGE, CONST-
ANTLY GOING DOWN  BY THE THREE LAST DAY OF PERIOD. ESTIMATED,  WEEK-
LY AVERAGE VALUE OF THE RELATIVE SUNSPOT NUMBER IN THE INTERNATIONAL 
SYSTEM WAS MADE W = 59+18/-12.  ON THE VISIBLE SOLAR DISK CONSTANTLY 
OBSERVED 5-6 SUNSPOT GROUPS, TWO OF WHICH WERE THE MIDDLE SIZE.

 NEXT WEEK IS EXPECTED THE MODERATE LEVEL OF SUNSPOT-FORMING ACTIVI-
TY.  ESTIMATED, MOST LIKELY WEEKLY AVERAGE VALUE OF RELATIVE SUNSPOT 
NUMBER IN THE INTERNATIONAL SYSTEM FOR THE NEXT WEEK IS EXPECTED W=
050+20/-20.

 FLARE ACTIVITY WAS AT THE THE LOW LEVEL. WITHIN THE PERIOD WERE OB-
SERVED 3 SOLAR FILAMENT EJECTIONS. BY SOHO AND STEREO CORONOGRAPHS 
DATA THERE WERE OBSERVED 46 CME, ONE OF WHICH WAS THE TYPE OF "PAR-
TIAL HALO II".

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT VERY HIGH 
LEVEL BEGAN 25.04/1835 UT AND WAS OBSERVED 28.04.

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

THE GEOMAGNETIC CONDITIONS REMAINED GENERALLY UNSETTLED AND QUITE. HOWEVER 
30.04 AND 4.05 ITS WERE ACTIVE: IN THE FIRST DAY ACCORDING TO IZMIRAN (G1)  
AND THE CENTER IN BOULDER (G0) THE SUBSTORM OF 9 h. DURATION WAS NOTED. 

NEXT WEEK THE GEOMAGNETIC CONDITIONS ARE EXPECTED UNSETTLED AND QUIET.
