THE RELATIVE MONTHLY MEAN SUNSPOT NUMBER ON MAY 2013 HAS MADE

W may= 78.7,

THAT GIVES FOR 49 MONTH (2012, NOVEMBER) DEVELOPMENT CURRENT 24 CYC-

LES OF SOLAR ACTIVITY THE SMOOTHED MONTHLY MEAN SUNSPOT NUMBER

W*oct.= 59.7

THE BEGINNING 24 CYCLES OF SOLAR ACTIVITY - I 2009 with W*=1.8

THE MOST PROBABLE TIME OF THE MAXIMUM OF THE CURRENT CYCLE-

XI.2012 - IX 2013

THE MOST PROBABLE HEIGHT OF THE MAXIMUM - Wmax = 66 - 75.

THE MONTHLY MEAN OF OBSERVED RADIO FLUX OF THE 10 cm (2800 MHz)ON

2013, MAY F may. = 131.4



THE MONTHLY MEAN OF GEOMAGNETIC Ap-index ON 2013, MAY

Ap may. = 9.04



Values of smoothed Wolf numbers it is sure increase, designating

SECOND peak of the current solar cycle development. If it appears

greatest of several (in their 14th solar cycle was 4 and the maxi-

mum fell on the second), it and there will be a maximum 24 cycles

of solar activity.

Weekly Bulletin on Solar and Geomagnetic Activity

Highlights on 27.05 - 01.06.2013,

Forecast on 02 - 10.06.2013,

Carrington Rotations 2137 (15,02.05.2013)



SUNSPOT-FORMING ACTIVITY OF THE SUN REMAINED ON THE AVERAGE LEVEL.

WEEKLY, THE AVERAGE OF SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM

FOR THE PERIOD WAS MADE W=043+14/-1. ON THE VISIBLE SOLAR DISK CON-

STANTLY THERE WERE 6 - 4 SMALL SUNSPOTS GROUPS.



NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY IS EXPECTED TO BE THE AVERAGE

AND THE LOW LEVEL. THE CALCULATED MOST LIKELY WEEKLY AVERAGE VALUE OF

SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR THE NEXT WEEK IS EXPEC-

TED W = 050+20/-10.



FLARE ACTIVITY WAS AT THE AVEREGE LEVEL 31 MAY, THE LOW - 30.05 AND THE

VERY LOW - ON OTHER DAYS. THERE WERE 2 EJECTION OF SOLAR FILAMENTS OB-

SERVED IN THIS PERIOD. BY SOHO AND STEREO CORONOGRAPHS DATA THERE WERE

OBSERVED 38 CME FROM WHICH ONE WAS THE TYPE OF "HALO", AND 2 WERE THE

TYPE OF "PARTIAL GALO II".

GEOMAGNETIC CONDITION CHANGED FROM UNSETTLED TO MAGNETIC STORM. 27 MAY.

THE MINOR MAGNETIC STORM REGISTERED (G0; Ams = 27; dur = 12 h) ACCORDING

IZMIRAN DATA. ACCORDING TO THE CENTER IN BOULDER DATA GEOMAGNETIC CONDI-

TION DURING THOSE HOURS WAS ACTIVE. 31 MAY, AT THE END OF THE DAY, AFTER

COMING TO EARTH INTERPLANETARY SHOCK WAVE (SI 31/1618), WAS REGISTERED

THE MAGNETIC STORM, WHICH, ACCORDING IZMIRAN DATA, WAS MODERATE (G1; Ams

=45; dur.=18 h.). ACCORDING TO THE CENTER IN BOUDER THIS MAGNTTIC STORM

IS A MAJOR (G2; Ams= 73; dur.=15 h.). LIKELY SOURCES OF THAT DISTURBANCE

WERE A SOLAR FILAMENT EJECTA AT 29.05, WHICH WAS ACCOMPANIED BY CME "PAR-

TIAL HALO II" TYPE AND THE HIGH-SPEED SOLAR WIND STREAM FROM A LARGE NEAR

EQUATORIAL CORONAL HOLE WHICH EARTH WAS PASSED. OTHER DAYS THE GEOMAGNETIC

CONDITION REMAINED UNSETTLED



NEXT WEEK THE GEOMAGNETIC CONDITION IS EXPECTED UNSETTLED AND QUIET.
