THE RELATIVE MONTHLY MEAN SUNSPOT NUMBER ON OCTOBER 2012 HAS MADE
Woct.= 53.3,
THAT GIVES FOR 40 MONTH (2012, APRIL) DEVELOPMENT CURRENT 24 CYCLES
OF SOLAR ACTIVITY THE SMOOTHED MONTHLY MEAN SUNSPOT NUMBER
W*apr.= 64.6
THE BEGINNING 24 CYCLES OF SOLAR ACTIVITY - JANUARY, 2009 with W*=1.8
THE MOST PROBABLE TIME OF THE MAXIMUM OF THE CURRENT CYCLE-
09 - 12.2012
THE MOST PROBABLE HEIGHT OF THE MAXIMUM - Wmax = 60 - 90.

THE MONTHLY MEAN OF OBSERVED FLUX OF THE 10 cm (2800 MHz)ON 2012,
OCTOBER F*oct. = 123.3

THE MONTHLY MEAN OF GEOMAGNETIC Ap-index ON 2012, OCTOBER
Ap oct. = 10.4

Values of the smoothed numbers of Wolf went down after 2012, February
designating first peak of the current solar cycle development. If it
appears the greatest from several (in their 14th solar cycle was 4 and
the maximum fell on the second), it there will be a maximum 24 cycles
of solar activity.

Weekly Bulletin on Solar and Geomagnetic Activity
Highlights on 29.10 - 04.11.2012,
Forecast on 05 - 12.11.2012,
Carrington Rotations 2129, 2130 (8,57.10; 04,86.11.2012)


SUNSPOT-FORMING ACTIVITY OF THE SUN WAS REMAINED ON THE AVERAGE LEVEL.
WEEKLY, THE AVERAGE OF SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR
THE PERIOD WAS MADE W=028+17/-8. ON THE VISIBLE SOLAR DISK CONSTANTLY
THERE WERE PRESENT 3-4 SMALL SUNSPOTS GROUPS.

NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY IS EXPECTED TO BE THE LOW AND
THE AVERAGE. THE CALCULATED MOST LIKELY WEEKLY AVERAGE VALUE OF SUN-
SPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR THE NEXT WEEK IS EXPECTED
W = 040+10/-20.

FLARE ACTIVITY WAS ON THE LOW LEVEL AT OCTOBER 31, AND THE VERY lOW
IN OTER DAYS. BY DATA OF SOHO AND STEREO CORONOGRAPHS FOR THE PERIOD
IT WAS OBSERVED 29 CME AMONG WHICH ONE - "PARTIAL HALO III" AND ONE -
"PARTIAL HALO II".

ON THE FOLLOWING WEEK FLARE ACTIVITY IS EXPECTED ON THE LOW AND VERY

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT VERY HIGH
LEVEL WAS NOT OBSERVED.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT VERY HIGH
LEVEL IS NOT EXPECTED.

THE GEOMAGNETIC CONDITIONS WERE ON THE MINOR MAGNETIC STORM LEVEL (G0,
Ams=27, dur.=12 h.) ACCORDING TO IZMIRAN DATA AND ACTIVE-ACCORDING TO
THE CENTER IN BOULDER DATA. IN OTHER DAYS THE GEOMAGNETIC CONDITIONS
REMAINED QUIET AND UNSETTLED.

NEXT WEEK THE GEOMAGNETIC CONDITION IS EXPECTED UNSETTLED AND QUIET,
HOWEVER ON OCTOBER 5-6 ACCORDING TO THE BOULDER DATA GROWTH OF GEOMAG-
NETIC DISTURBANCE BECAUSE OF TRIPLE CME FROM DSFs ON WEST HEMISPHERE
OF SOLAR VISIBLE DISK ARRIVAL IS POSSIBLE. INFORMATION HAS NOT ENOUGH
TO PLACE THEM IN THE CORRESPONDING TABLE.
