THE RELATIVE MONTHLY MEAN SUNSPOT NUMBER ON AUGUST 2012 HAS MADE
Waug.= 63.1,
THAT GIVES FOR 38 MONTH (2012, FEBRUARY) DEVELOPMENT CURRENT 24 CYCLES
OF SOLAR ACTIVITY THE SMOOTHED MONTHLY MEAN SUNSPOT NUMBER
W*feb.= 66.9
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 INTERNATIONAL DAILY VALUE OF RELATIVE SUNSPOT NUMBER FOR 2012,

THE MONTHLY MEAN OF OBSERVED FLUX OF THE 10 cm (2800 MHz) ON 2012, AUGUST
F*aug. = 115.4
THE MONTHLY MEAN OF GEOMAGNETIC Ap-index ON 2012, AUGUST
Ap aug. = 7.53

It became so far clear that the current solar cycle didn't become
lowest of authentic cycles of solar activity. The lowest
solar cycle there was N14.

Weekly Bulletin on Solar and Geomagnetic Activity
Highlights on 27.08 - 02.09.2012,
Forecast on 03 - 10.09.2012,
Carrington Rotation 2127 (15,04.08.2012)

SUNSPOT ACTIVITY OF THE SUN REMAINED AT THE AVERAGE LEVEL. WEEKLY, THE
AVERAGE OF SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR THE PERIOD
WAS MADE W=064+22/-20. ON THE VISIBLE SOLAR DISK CONSTANTLY THERE WERE
4-5 SUNSPOT GROUPS ONE OF WHICH, APPEARING ON THE VISIBLE SOLAR DISK
ON AUGUST 25, AVERAGE SIZES.

NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY IS EXPECTED TO BE AVERAGE. THE
CALCULATED MOST LIKELY WEEKLY AVERAGE VALUE OF SUNSPOT NUMBER IN THE
INTERNATIONAL SYSTEM FOR THE NEXT WEEK IS EXPECTED W=050+20/-20.

FLARE ACTIVITY WAS ON THE MIDDLE LEVEL AT AUGUST 30 AND OTHER DAYS -
ON LOW. BY DATA OF SOHO AND STEREO CORONOGRAPHS FOR THE PERIOD IT WAS
OBSERVED 31 CME AMONG WHICH ONE WAS TYPE "HALO" AND ONE WERE "PARTIAL
HALO II".

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT VERY HIGH
LEVEL WAS OBSERVED 27 - 31 AUGUST.

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

GEOMAGNETIC ACTIVITY REMAINED QUITE AND ACTIVE. HOWEVER, ON MARCH 2
AFTER THE ARRIVAL AT THE EARTH OF INTERPLANETARY DISTURBANCE FROM THE
FLARE C8.5/2F AND THE SOLAR FILAMENT EJECTION OF THE FLARE ASSOCIATING
(SI - 2/1214 UT) IN THE END OF THE DAY ACCORDING TO THE DATA OF CENTER
IN BOULDER IS NOTED THE PROLONGED (12 HOURS) SUBSTORM, WHICH IN THE
INTENSITY DID NOT REACH THE THRESHOLD OF MINOR MAGNETIC STORM; HOWEVER,
ACCORDING TO THE DATA IZMIRAN GEOMAGNETIC CONDITION WAS UNSETTLEDED.

NEXT WEEK THE GEOMAGNETIC CONDITIONS IS EXPECTED ACTIVE WITH MAGNETIC
STORMS 3-5 SEPTEMBER. IN OTHER DAYS GEOMAGNETIC CONDITIONS IS EXPECTED
UNSETTLED AND QUIET.
