THE RELATIVE MONTHLY MEAN SUNSPOT NUMBER ON JULY 2011 HAS MADE
Wjuly =43.9,
THAT GIVES FOR 25 MONTH (2011, JANUARY) DEVELOPMENT CURRENT 24 CYCLES OF
SOLAR ACTIVITY THE SMOOTHED MONTHLY MEAN SUNSPOT NUMBER
W*jan. = 31.0
THE BEGINNING 24 CYCLES OF SOLAR ACTIVITY - JANUARY, 2009 with W*=1.8
THE MOST PROBABLE TIME OF THE MAXIMUM OF THE CURRENT CYCLE - 02-06 2013
(Date of approach of a maximum of a current cycle close to a reality can
be defined only after 18 - 24 months of its development).

THE MAXIMUM OF 23 SOLAR CYCLE HAS COME IN APRIL 2000 WITH VALUE
OF THE SMOOTHED MONTHLY WOLF'S NUMBER - W*= 120.7
SECONDARY MAXIMUM OF THE CYCLE IS NOTED IN NOVEMBER 2001 - W*= 115.6
MAXIMUM OF THE RADIO EMISSION ON 10 cm FLUX - F*= 197.2
HAS COME IN FEBRUARY 2002.
THE OF THE 23 CYCLE MINIMUM - DECEMBER 2008 with W*=1.7.
The most probable height according to all available information will make
current 24 cycles of solar activity Wmax = 50 - 70.
Possible specifications after 28 months of development of a cycle (on the
smoothed values of relative Wolf number).

Forecast on 01 - 08.08.2011,
Carrington Rotations 2112 2113 (03,01 - 30,22.07.2011)

SOLAR SUNSPOT ACTIVITY OF THE LAST PERIOD KEPT CLOSE TO LOW AND MIDDLE
LEVELS. ESTIMATED, RATING, WEEKLY AVERAGE OF SUNSPOT NUMBER IN THE
INTERNATIONAL SYSTEM FOR THE PERIOD WAS MADE W=045+32/-27. ON THE
VISIBLE SOLAR DISK WAS CONSTANTLY PRESENT BETWEEN 8 AND 3 OF SMALL
QUITE SUNSPOT GROUPS.

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

FLARE ACTIVITY WAS AT HIGH LEVEL ON JULY, 30th, WHEN IN SUNSPOT GROUP
AR11261 (N16L330, Sp=350 m.v.h) THE LARGE PULSE SOLAR FLARE OF X-RAY
CLASS М9.3 WAS OCCURENCED, AT THE AVERAGE LEVEL - ON JULY, 27th, OTHER
DAYS - ON A LOW LEVEL. SOHO CORONOGRAPH HAVE REGISTRED 46 CORONAL MASS
EJECTIONS FROM THEM 4 (25, 26 AND 28 JULY) WAS OF TYPE "PARTIAL HALO II"
(90-180 deg.).

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT EXCEEDS THE
THRESHOLD IN 1000 p.f.u. 20/1250 UT UT AND VERY HIGH LEVEL OF FLUX OBSERVED
25-29.07.

NEXT WEEK THE GREATER THAN 2 MeV ELECTRON FLUX AT HIGH LEVEL IS NOT EXPECTED.

ON JULY, 30-31th ACCORDING TO GEOMAGNETIC OBSERVATORIES OF THE WESTERN
HEMISPHERE THE MINOR MAGNETIC STORM STRETCHED ON TIME (G1, Ams=29, dur.
= 12 h.), HOWEVER ACCORDING TO IZMIRAN DATA GEOMAGNETIC CONDITIONS THESE
DAYS WERE ONLY UNSETTLED, WITHOUT REACHING PARAMETERS OF THE MAGNETIC STORM.
IN OTHER DAYS GEOMAGNETIC CONDITIONS WERE UNSETTLED AND QUIET.

NEXT WEEK IT IS MOST PROBABLE QUIET AND UNSETTLED GEOMAGNETIC CONDITIONS.
