Weekly Bulletin on Solar and Geomagnetic Activity
                 Highlights on 19 - 25.11.2018,
                 Forecast on 26.11 - 02.12.2018,
   Carrington Rotation 2210, 2211 (26,87.10; 23,17.11.2018)
            Earth out of ecliptic (+4.9 - +4.82) deg. 
             (S23 - N24 is zone of geoeffectiveness)

THE SUNSPOT-FORMING ACTIVITY OF THE SUN HAVE REMAINED  AT THE LOW 
AND VERY LOW. 20 - 23.11 THE SUN WAS SPOTLESS. ESTIMATED, MOST LI-
KELY  WEEKLY  AVERAGE VALUE OF THE RELATIVE SUNSPOT NUMBER IN THE 
INTERNATIONAL SYSTEM (old) FOR PERIOD W = 004+3/-4 (Wn = 6+8/-6). 
ON VISIBLE SOLOAR DISC TWO SMALL SUNSPOT GROUP HAVE BEEN OBSERVED.

NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY WILL STAY AT A VERY LOW LE-
VEL. LIKELY WEEKLY AVERAGE VALUE OF THE RELATIVE SUNSPOT NUMBER IN 
THE INTERNATIONAL SYSTEM (old) FOR THE NEXT WEEK IS W= 010+10/-10. 

 THE FLARE ACTIVITY  WAS ON THE VERY LOW LEVEL. ONE  CORONAL MASS 
EJECTIONS HAVE BEEN OBSERVED.

 THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT HAVE 
NOT BEEN OBSERVED.  
 
 NEXT WEEK THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS 
ORBIT IS NOT EXPECTED.

THE GEOMAGNETIC CONDITION REMAINED UNSETTLED AND QUITE.

 THE NEXT WEEK IS MOST PROBABILITY OF QUIET AND UNSETTLED GEOMAGNE-
TIC CONDITION.
