 On July 1, 2015 Centre in Brussels moved to a new system of calcu-
lation 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.

      Weekly Bulletin on Solar and Geomagnetic Activity
              Highlights on 29.01- 04.02.2018,
                Forecast on 05 - 12.01.2018,
         Carrington Rotation 2200 (27,28.01.2018)
        Earth out of ecliptic (-5.6 - -6.2) deg. 
             (S30 - N24 is geoeffectiveness zone)
(for my carelessness in the line "Earth out of ecliptic", incor-
rect data has been published in recent months.
In January, the Earth was projected onto the visible disk of the 
Sun in the interval from -3.0 to -5.9 degrees. I apologize...)

 SUNSPOT-FORMING ACTIVITY WAS ON THE VERY LOW LEVEL AND THE SUN 
WAS SPOTLESS 29.01, 1 AND 3.02 (18 DAYS-IN 2018). THE ESTIMATED, 
MOST LIKELY WEEKLY AVERAGE VALUE OF THE RELATIVE SUNSPOT NUMBER  
IN THE INTERNATIONAL SYSTEM (old) FOR THE PERIOD W=004+5/-4 (Wn
= 006+8/-6). ON THE VISIBLE SOLAR DISK 3 SMALL, SHORT-LIVED QUI-
ET SUNSPOT GROUPS, ALL IN THE SOUTHERN HEMISPHERE HAVE BEEN OB-
SERVED.

 NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY WILL BE ON THE LOW AND 
VERY LOW LEVEL. LIKELY WEEKLY AVERAGE VALUE OF THE RELATIVE SUN-
SPOT NUMBER IN THE INTERNATIONAL SYSTEM (old) FOR THE NEXT WEEK 
IS W = 010+10/-10.  

 FLARE ACTIVITY  WAS ON THE LOW LEVEL AT4.09 AND VERY LOW LEVEL 
IN OTHER DAYS. EJECTA OF SOLAR FILAMENTS AND CORONAL MASS EJEC-
TIONS WERE NOT OBSERVED.

AFTER C 29.01/0610 UT EARTH IS IN "-" SECTOR OF INTERPLANETARY MAGNETIC
FIELD, BUT THE SIGN OF SECTOR IS VERY UNSTABLE AND FREQUENTLY CHANGING. 
NEXT SECTOR BOUNDARY -/+ EARTH MUST PASS 10-11.02.

OBSERVED.
 
NEXT WEEK THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS OR-

GEOMAGNETIC CONDITION WAS QUIET IN THE PERIOD.  

NEXT WEEK THE GEOMAGNETIC CONDITION IS EXPECTED UNSETTLED AND  QUIET.
