Weekly Bulletin on Solar and Geomagnetic Activity
Highlights on 21 - 27.04.2014 Г.,
Forecast on 28.04 - 4.05.2014,
Carrington Rotation 2149,2150 (7,36.04; 04,62.05.2014)

SUNSPOT-FORMING ACTIVITY OF THE SUN CHANGED FROM HIGH LEVEL (21.04)
TO THE AVERAGE, CONSTANTLY GOING DOWN BY THE PERIOD END. AVERAGE OF
SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM WAS MADE W=59+42/-14. ON
THE VISIBLE SOLAR DISK CONSTANTLY OBSERVED 8-3 SMALL SUNSPOT GROUPS

NEXT WEEK IS EXPECTED THE MODERATE AND THE LOW LEVELS OF SUNSPOT-
FORMING ACTIVITY. ESTIMATED MOST LIKELY WEEKLY AVERAGE VALUE OF RE-
LATIVE SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR THE NEXT
WEEK IS EXPECTED W=050+20/-20.

FLARE ACTIVITY WAS AT THE HIGH LEVEL 25.04, AND THE LOW LEVEL - IN
OTHER DAYS. WITHIN THE PERIOD WERE OBSERVED 9 SOLAR FILAMENT EJECTI-
ONS. BY SOHO AND STEREO CORONOGRAPHS DATA THERE WERE OBSERVED 43 CME,
SIX OF WHICH WERE THE TYPE OF "PARTIAL HALO II".

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT VERY HIGH
LEVEL BEGAN 25.04/1835 UT AND WAS OBSERVED 25-27.04.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT VERY HIGH
LEVEL BE EXPECTED 28 - 30.04.

THE GEOMAGNETIC CONDITIONS REMAINED GENERALLY UNSETTLED AND ONLY
24-25.04 BY DATA IZMIRAN WAS ACTIVE.

NEXT WEEK THE GEOMAGNETIC CONDITIONS ARE EXPECTED UNSETTLED AND QUIET.
