Weekly Bulletin on Solar and Geomagnetic Activity Highlights on 13 - 19.01.2014, Forecast on 20 - 27.01.2014, Carrington Rotation 2145, 2146 (19,05.12.2013, 15.39.01.2014) SUNSPOT-FORMING ACTIVITY OF THE SUN REMAINED AT THE AVERAGE LEVEL. WEEKLY, THE AVERAGE OF SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM WAS MADE W=057+11/-11. ON THE VISIBLE SOLAR DISK CONSTANTLY OBSER- VED 6-10 SMALL QUITE SUNSPOT GROUPS. LARGE SUNSPOT GROUP (AR11944, S04L097, Sp=1560 mvh) GONE FOR W-LIMB PRACTICALLY UNCHANGED on 14.01. 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 AVERAGE LEVEL 8.01 AND LOW LEVEL IN OTHER DAYS. DURING THE REPORTING PERIOD 4 EJECTA OF SOLAR FILAMENT, NON GEOEFFCTIVE. BY SOHO AND STEREO CORONOGRAPHS DATA THERE WERE OBSER- VED 39 CME FROM WHICH FIVE WERE "PARTIAL HALO II" TYPE. -------------------------------------------------------------------- FLARES to tm te c/p local.
