THE RELATIVE MONTHLY MEAN SUNSPOT NUMBER ON NOVEMBER 2015 HAS MADE
Wnov. = 37.1, 63.2 (new)
THAT GIVES FOR 75 MONTHS (2015, APRIL) DEVELOPMENT CURRENT 24 CYCLE
OF SOLAR ACTIVITY THE SMOOTHED MONTHLY MEAN SUNSPOT NUMBER
W*may = 45.6; 76.0 - in new system;
W*apr. = 49.3; 78.9 - 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.

Weekly Bulletin on Solar and Geomagnetic Activity
Highlights on 30.11 - 06.12.2015,
Forecast on 07 - 14.12.2015,
Carrington Rotation 2171 (28,17.11.2015)

SUNSPOT-FORMING ACTIVITY OF THE SUN CHANGED FROM THE MIDDLE TO LOW
LEVEL. ESTIMATED, WEEKLY AVERAGE VALUE OF THE RELATIVE SUNSPOT NUM-
BER IN THE INTERNATIONAL SYSTEM (old) WAS W=22+9/-7 (Wн=35+14/-11).
ON THE VISIBLE SOLAR DISK 2 - 4 SMALL QUITE SUNSPOT GROUPS HAVE
BEEN OBSERVED.

THE MIDDLE AND THE LOW LEVEL OF THE SUNSPOT-FORMING ACTIVITY IS EX-
PECTED ON THE NEXT WEEK. AS ESTIMATED, THE MOST LIKELY WEEKLY AVE-
RAGE VALUE OF THE RELATIVE SUNSPOT NUMBER IN THE INTERNATIONAL SYS-
TEM FOR THE NEXT WEEK IS W = 030+15/-15.

FLARE ACTIVITY ALL DAYS WAS AT THE LOW LEVEL. ACCORDING TO THE DATA
FROM SOHO AND STEREO CORONOGRAPHS > 22 CMEs, ONE-A TYPE II (angular
width 180 - 270 deg.) HAVE BEEN OBSERVED.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT WAS WAS
BEGINNING AT 02.12/1610 UT AND WAS OBSERVED 2 - 4.12.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT OF VERY
HIGH LEVEL IS EXPECTED 9 - 14.12.

THE GEOMAGNETIC CONDITION WAS ACTIVE 30.11-1.12 ANDd 5-6.12. THE MI-
NOR MAGNETIC STORM (G1, Ams = 29, dur. = 15 h.) It WAS NOTED ONLY AC-
CORDING TO THE CENTER IN BOULDER. THE SECOND, ALREADY TO DATA OF
IZMIRAN, THE MINOR MAGNETIC STORM (G1, Ams= 39, dur. = 12 h.) IT WAS
OCCURENCED IN THE SECOND HALF 1.12 (9-hour G0-SUBSTORM ACCORDING TO
THE CENTER IN BOULDER DATA). ACCORDING TO THE CENTER In BOULDER 5.11
THE MINOR MAGNETIC STORM is NOTED (G0, Ams=25, dur. = 15 h.), 6-hour
G0-SUBSTORM TO IZMIRAN DATA. AND, AT LAST, ON DECEMBER, 6 THE MINOR
MAGNETIC STORM (G1, Ams=~25, dur.=>27 h., continued) WAS ODSERVED TO
THE CENTER IN BOULDER AND (G1, Ams=31, dur.= 15 h.) ON IZMIRAN DATA.
IN OTHER DAYS THE GEOMAGNETIC CONDITION WAS QUIET AND UNSETTLED.

NEXT WEEK THE GEOMAGNETIC CONDITION IS EXPECTED ACTIVE 7-8.12, WHEN
THE EARTH WILL PASS THE HIGH-SPEED STREAMS OF THE SOLAR WIND FROM THE
CORONAL HOLE OF POSITIVE POLARITY. PROBABILITY OF GEOMAGNETIC STORM
~60%.
