THE RELATIVE MONTHLY MEAN SUNSPOT NUMBER ON JULY 2012 HAS MADE
Wjuly= 66.5,
THAT GIVES FOR 37 MONTH (2012, JANUARY) DEVELOPMENT CURRENT 24 CYCLES

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 GEOMAGNETIC Ap-index ON 2012, JULY

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 the solar cycle N14.

Weekly Bulletin on Solar and Geomagnetic Activity
Highlights on 30.07 - 05.08.2012,
Forecast on 06 - 13.08.2012,
Carrington Rotation 2126 (18.82.07.2012)

SUNSPOT ACTIVITY OF THE SUN REMAINED AT THE AVERAGE LEVEL, HOWEVER ON
JULY 3 ROSE TO THE HIGH. WEEKLY, THE AVERAGE OF SUNSPOT NUMBER IN THE
INTERNATIONAL SYSTEM FOR THE PERIOD WAS MADE W=075+21/-11. ON THE VI-
SIBLE SOLAR DISK CONSTANTLY THERE WERE 6-12 SUNSPOT GROUPS, ONE OF
THEM, AR11532 (S20L185), GRADUALLY DEGRADING, BECAME AT FIRST THE AVE-
RAGE, AND SINCE AUGUST 1 THE SMALL SIZE:
AR11532 (S20L185, Sp= 510 m.v.h. on 28.07)- it was appeares on the vi-
sible disk 25.07. Fast development with August 27 on 28 with increase
of sunspot area in 6.5 times and at the end of the days a large flare
was occurrences. In only 37 hours on July 27-30 in this active region
were occurence 1 large and 2 flares of the average class.

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=060+10/-10.

FLARE ACTIVITY WAS ON THE AVERAGE LEVEL AT 30.07, AND THE LOW IN OTHER
DAYS. BY DATA OF SOHO AND STEREO CORONOGRAPHS FOR THE PERIOD IT WAS OB-
SERVED 73 CME AMONG WHICH ONE WAS "HALO" TYPE, ONE OF "PARTIAL HALO III"
AND 3 WERE "PARTIAL HALO II".

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.

GEOMAGNETIC ACTIVITY WERE ACTIVE ON JULY 30 AND ON AUGUST 2 WHEN TWO
SUBSTORMS WERE REGISTERED BY DURATION OF 6 HOURS (G1) AND OF 9 HOURS
(G1). IN OTHER DAYS THE GEOMAGNETIC SITUATION REMAINED UNSETTLED AND
QUIET.

NEXT WEEK THE GEOMAGNETIC SITUATION IS EXPECTED UNSETTLED AND QUIET,
HOWEVER AUGUST 6, 8 AND 10 THE SEPARATE PERIODS OF ACTIVE ARE POSSIBLE.
