Weekly Bulletin on Solar and Geomagnetic Activity Highlights on 17 - 23.11.2014, Forecast on 24 - 30.11.2014, Carrington Rotation 2157 (11.30.11.2014) SUNSPOT-FORMING ACTIVITY OF THE SUN WAS AT THE AVERAGE LEVEL. ESTIMATED, WEEKLY AVERAGE VALUE OF THE RELATIVE SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM WAS MADE W = 054+16/-16. ON THE VI- SIBLE DISK OF THE SUN CONSTANTLY OBSERVED 5 - 3 SUNSPOT GROUPS, TWO OF WHICH WAS LARGE SIZE: AR12209 (S13L264, CMP 18.11.2014, Sp max= 1100 mvh) -appearance on east limb at 11.11, it consisting of two interacting parts. In 30 hours on 15-16.11 in tail, northwest part of sunspot group there were the flare of X-ray class 1 large and 2 middle. After 16.11 significant flares were not. AR12216 (S13L164, CMP 25.11.2014, Sp max = 640 ÍÄÐ) left because of E-limb quite created quiet sunspot group. In both sunspot groups significant flares are possible only at emergence of new magnetic fluxes that so far, judging by dynamics of their development, it is improbable. NEXT WEEK EXPECTED AVERAGE, AND BY END OF THE PERIOD POSSIBLE AND THE LOW SUNSPOT ACTIVITY. ESTIMATED, MOST LIKELY WEEKLY AVERAGE VALUE OF RELATIVE SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR THE NEXT WEEK IS EXPECTED W = 040+20/-20. FLARE ACTIVITY WAS AT THE LOW LEVEL ALL DAYS. THERE IS ONE EJEC- TIONS OF THE SOLAR FILAMENT. BY DATA OF CORONOGRAPHS SOHO AND STE- REO WERE OBSERVED 33 CME. ------------------------------------------------------------------- FLARES to tm te c/p local.Class E(1-8A) AR RII/IV CME X-ray/Ïp J/m-2 DSF to te c/p local. l in deg.

IN CASE OF EMERGENCE OF THE NEW MAGNETIC FLUX LARGE FLARES ARE POSSIBLE IN AR 12209 AND AR12216.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT VERY HIGH LEVEL WAS BEGAN AT 16.11 AND OBSERVED 17 - 20 NOVEVBER. THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT VERY HIGH LEVEL IS NOT EXPECTED. THE GEOMAGNETIC CJNDITIONS LAST WEEK WAS FORMALLY UNSETTLED AND QUIET THOUGH SUBSTORMS WERE ALMOST EVERY DAY OBSERVED INTENSITY (G0 - a K- index 4) AND DURATION UP TO 6 HOURS. NEXT WEEK CHARACTER OF THE SPACE ENVIRONMENT CONDITIONS WON'T CHANGE: AGAINST THE RESULTANT QUIET AND UNSETTLED OF THE GEOMAGNETIC CONDITI- ONS CAN BE REGISTERED SEPARATE MINOR SUBSTORMS.
