Weekly Bulletin on Solar and Geomagnetic Activity Highlights on 20 - 26.01.2014, Forecast on 27.01 - 03.02.2014, Carrington Rotation 2146 (15.39.01.2014) SUNSPOT-FORMING ACTIVITY OF THE SUN REMAINED AT THE AVERAGE LEVEL AND ONLY 24.01 NOTED THE HIGH LEVEL. WEEKLY, THE AVERAGE OF SUN- SPOT NUMBER IN THE INTERNATIONAL SYSTEM WAS MADE W = 077+13/-12. ON THE VISIBLE SOLAR DISK CONSTANTLY OBSERVED 7-10 SMALL QUITE SUNSPOT GROUPS. NEXT WEEK IS EXPECTED THE AVERAGE AND THE HIGH LEVEL OF SUNSPOT-FOR- MING ACTIVITY. ESTIMATED MOST LIKELY WEEKLY AVERAGE VALUE OF RELATI- VE SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR THE NEXT WEEK IS EXPECTED W=070+20/-20. FLARE ACTIVITY WAS AT THE LOW LEVEL IN ALL DAYS. DURING THE REPORT- ING PERIOD WERE 2 EJECTA OF SOLAR FILAMENT, NON GEOEFFCTIVE. BY SOHO AND STEREO CORONOGRAPHS DATA THERE WERE OBSERVED 40 CME FROM WHICH 2 WERE "PARTIAL HALO III" TYPE AND 4 - "PARTIAL HALO II". -------------------------------------------------------------------- FLARES to tm te c/p local.
