THE RELATIVE MONTHLY MEAN SUNSPOT NUMBER ON MARCH 2016 HAS MADE
Wmarch = 32.9, 54.9 (new)
THAT GIVES FOR 80 MONTHS (2015, SEPTEMBER) DEVELOPMENT CURRENT 24
CYCLE OF SOLAR ACTIVITY THE SMOOTHED MONTHLY MEAN SUNSPOT NUMBER
W*sep. = 39.6; 66.0 - (in new system);
W*aug. = 39.8; 66.3 - (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 28.03 - 03.04.2016,
Forecast on 04 - 11.04.2016,
Carrington Rotations 2175 (16,50.03.2016)

SUNSPOT-FORMING ACTIVITY OF THE SUN WAS AT A LOW LEVEL ALL DAYS,
EXCEPT 3.04 - AVERAGE. THE ESTIMATED MOST LIKELY WEEKLY AVERAGE
VALUE OF THE RELATIVE SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM
(old)FOR THE PERIOD IS W=10+13/-7 (Wn=16+20/-4). 2 - 1 SMALL AND
QUITE SUNSPOT GROUPS WERE CONSTANTLY OBSERVED ON THE VISIBLE SO-
LAR DISK.

NEXT WEEK IT IS EXPECTED THE AVERAGE AND THE LOW LEVELS OF SUN-
SPOT-FORMING ACTIVITY. THE ESTIMATED, THE MOST LIKELY WEEKLY AVE-
RAGE VALUE OF THE RELATIVE SUNSPOT NUMBER IN THE INTERNATIONAL
SYSTEM (old) FOR THE NEXT WEEK IS W = 020+20/-10.

FLARE ACTIVITY WAS AT THE VERY LOW LEVEL ALL DAYS. THERE WERE FO-
UR SOLAR FILAMENT EJECTION OCCURRENCES THROUGH THE PERIOD. ACCOR-
DING TO THE DATA FROM SOHO AND STEREO CORONOGRAPHS, >12 CMEs HAVE
BEEN OBSERVED.

MINOR MAGNETIC STORM (G2, Ams=39, dur.=12 h) HAS BEEN NOTED 2 -3.04
AS A RESULT OF PASSING BY THE EARTH OF THE SOLAR WIND HIGH-SPEED
STREAM FROM NEGATIVE POLARITY CORONAL HOLE OF THE NORTHERN HEMI-
SPHERE. IN OTHER DAYS THE GEOMAGNETIC CONDITION WAS UNSETTLED AND
QUIET.

NEXT WEEK THE GEOMAGNETIC CONDITION IS EXPECTED UNSETTLED AND QUITE.
