THE RELATIVE MONTHLY MEAN SUNSPOT NUMBER ON FEBRUARY 2016 HAS MADE
Wfeb. = 34.3, 57.2 (new)
THAT GIVES FOR 79 MONTHS (2015, AUGUST) DEVELOPMENT CURRENT 24 CYC-
LE OF SOLAR ACTIVITY THE SMOOTHED MONTHLY MEAN SUNSPOT NUMBER
W*aug. = 39.8; 66.3 - (in new system);
W*july = 41.0; 68.2 - (in new system);

- On July 1, 2015 Centre in Brussels moved to a new system of cal-
culation the relative number of sunspots and practically all of the
values were replaced throughout the numbered series of Wolf numbers
(see link). While there is addictive, I recalculated (0.6) to the
old system, but only W*, and present below the new values for the
minimum and maximum of 24 cycles SA.
Almost all the work using smooth W* have to lead to a new system,
if it remains.

THE BEGINNING OF 24 SOLAR CYCLE - I 2009 with W*=1.8; (2.2)
THE TIME OF THE CURRENT CYCLE MAXIMUM-IV 2014, - Wmax = 82;(116.4)

Forecast on 29.02 - 06.03.2016,
Carrington Rotation 2174 (18,17.02.2016)

SUNSPOT-FORMED ACTIVITY OF THE SUN WERE AT THE AVERAGE LEVEL.CAL-
CULATED, AVERAGE VALUE OF SUNSPOT RELATIVE NUMBER IN THE INTERNA-
TIONAL SYSTEM (old) FOR THE PERIOD MADE W=37+20/-14 (Wn=59+42/-22).
ON THE VISIBLE DISK OF THE SUN 3 - 7 SMALL QUITE SUNSPOT GROUPS WE-
RE CONSTANTLY OBSERVED.

THE MIDDLE LEVEL OF THE SUNSPOT-FORMED ACTIVITY IS EXPECTED ON THE
NEXT WEEK. ESTIMATED, THE MOST LIKELY WEEKLY AVERAGE VALUE OF THE
RELATIVE SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR THE NEXT
WEEK IS W = 030+15/-10.

FLARE ACTIVITY WAS AT THE VERY LOW LEVEL ALL DAY, EXCEPT 4.03 - THE
LOW LEVEL. FIVE EJECTIONS OF SOLAR FILAMENTS HAVE BEEN OBSERVED. AC-
CORDING TO SOHO AND STEREO CORONOGRAPHS DATA >17 CMEs, ONE WAS "PAR-
TIALE HALO II" TYPE (angular width 90 - 180 deg.).

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT WAS NOT
OBSERVED.

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

GEOMAGNETIC FIELD ACTIVITY REMAINED QUIET TO THE MIDDLE OF DAY 6.03
WHEN HAS BEEN NOTED MAJOR (G3, Ams= 65, dur.= 18 h.), ACCORDING TO THE
CENTER IN BOULDERE, AND (G2, Ams= 51, dur.= 12 h.) TO IZMIRAN DATA MAG-
NETIC STORM. DISTURBATION FROM EJECTION OF VERY LARGE SOLAR FILAMENTS
1.03 BECAME ITS SOURCE WITH THE HIGH PROBABILITY. GROUND OBSERVATORIES
HAVE NOT REGISTERED (perhaps, at the moment) THE SUDDEN COMMENCEMENT,
HOWEVER BY DATA ACE (especially in a magnetic field) SUCH IMPULSE IS
LOOKED THROUGH ABOUT 11 h UT.

NEXT WEEK THE GEOMAGNETIC CONDITION IS EXPECTED UNSETTLED AND QUIET.
