Weekly Bulletin on Solar and Geomagnetic Activity
               Highlights on  11 - 17.11.2019,
                 Forecast on 18 - 25.11.2019,
            Carrington Rotation 2223 (16,44.10.2019)   
             Earth out of ecliptic (4.5 - 4.1) deg. 
            (S20 - N25 is zone of geoeffectiveness)

 THE SUNSPOT-FORMING SOLAR ACTIVITY REMAINED VERY LOW WITH A SPOT-
LESS VISIBLE DISK (241 SPOTLESS DAYS IN THE YEAR - 75%). ESTIMATED,  
MOST LIKELY WEEKLY AVERAGE VALUE OF THE RELATIVE SUNSPOT NUMBER IN 
THE INTERNATIONAL SYSTEM (old) FOR PERIOD W= 0 (Wn=0). 

NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY WAS ON VERY LOW LEVEL. LI-
KELY  WEEKLY AVERAGE VALUE OF THE RELATIVE SUNSPOT NUMBER  IN THE 
INTERNATIONAL SYSTEM (old) FOR THE NEXT WEEK IS W=010+10/-10. 

 FLARE ACTIVITY  WAS AT THE VERY LOW LEVEL. NO SOLAR FILAMENT EJEC-
TION AND ONE CORONAL MASS EJECTION (17.11) HAVE BEEN OBSERVED.

SOLAR WIND PARAMETERS WERE AT BACKGROUND LEVELS THIS PERIOD UNDER A NO-
MINAL SOLAR WIND REGIME.

 AFTER 16.11/23 UT THE INTERPLANETARY MAGNETIC FIELD SIGN IS UNSTABLE, 
BUT IN THE AVERAGE ARE REMAINED "-".  THE NEXT PERIOD SECTOR BOUNDARY 
REMAINED UNSTABLE.

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 OR-
BIT IS NOT EXPECTED.

 THE GEOMAGNETIC FIELD AT MID-LATITUDES REMAINED UNSETTLED AND QUIET.

NEXT WEEK FROM 10.21, THE EARTH WILL PASS A HIGH-SPEED STREAM OF SOLAR
WIND FROM THE TRANS-EQUATORIAL CORONAL HOLE, WHICH ALREADY 4 ROTATIONS 
PROVIDES ON NEAR EARTH SPACE BY MINOR MAGNETIC STORMS. THE PROBABILITY 
OF A MINOR MAGNETIC STORM 21 - 22.11 AT LEAST 60%.  ON OTHER DAYS, THE 
MOST PROBABLY QUIET AND WEAKLY GROUNDED GEOMAGNETIC CONDITION.

 NEXT WEEK THE GEOMAGNETIC FIELD THE MOST PROBABLY IS EXPECTED QUIET 
 AND UNSETTLED.
