Weekly Bulletin on Solar and Geomagnetic Activity
Highlights on 18 - 26.10.2014,
Forecast on 27.10 - 03.11.2014,
Carrington Rotations 2156 (15,00.10.2014)

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 = 067+21/-31. ON THE VI-
SIBLE DISK OF THE SUN CONSTANTLY OBSERVED 2 - 7 SUNSPOT GROUPS,
ONE OF WHICH WAS OF GIGANTIC AR12192 (S13L252, CMP 23.10.2014,
Sp max = 2750 mvh) - it became the biggest sunspot group of the
current solar cycle and already it made four X-flares. It appe-
ars from east limb in the course of continuous emergence of sig-
nificant magnetic fluxes in northwest part of active region which
observed 3 periods of large flares: 1. 19 - 20.10 (36 h.) 1 large
flare; 2. 22.10 (14 h.) - 2; 3. 24 - 26.10 (60 h.) - 3. Now the
sunspot group was stabilized and before emergence of a new magne-
tic flux of large flares won't be still any more. Interesting fe-
ature of large flares in this active region - lack of significant
CME and rather weak burst in dm- and m- ranges of radio waves that
can testify to closeness magnetic configurations in a place of re-
alization of these flares - strong magnetic fields?. From here and
lack of solar proton events, particles can't leave..

NEXT WEEK THE AVERAGE AND AFTER 30.11 LOW LEVELS OF SUNSPOT-FOR-
MING ACTIVITY IS EXPECTED. ESTIMATED, MOST LIKELY WEEKLY AVERAGE
VALUE OF RELATIVE SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR
THE NEXT WEEK IS EXPECTED W = 040+10/-20.

FLARE ACTIVITY WAS AT THE HIGH LEVEL AT 19-20, 22, 25-26.10; MID
DLE LEVEL IN OTHER DAYS. THERE IS 3 EJECTIONS OF THE SOLAR FILA-
MENTS. BY DATA OF CORONOGRAPHS SOHO AND STEREO WERE OBSERVED 34
CME, ONE OF WHICH WAS THE "PARTIAL GALO II" TYPE.
