Weekly Bulletin on Solar and Geomagnetic Activity
                  Highlights on 02 - 08.11.2020,
                    Forecast on 09 - 16.11.2020,
               Carrington Rotation 2237(1,31.11.2020)   
                Earth out of ecliptic (5.1 - 4.6) deg. 
               (S25 - N30 is zone of geoeffectiveness)

THE SUNSPOT-FORMING SOLAR ACTIVITY REMAINED ON LOW AND MIDDLE
LEVELS. ESTIMATED, MOST LIKELY WEEKLY AVERAGE VALUE OF THE SUN-
SPOT NUMBER IN THE INTERNATIONAL SYSTEM (old) FOR PERIOD W=16+8
/-9 (Wn=26+14/-15). ON THE VISIBLE SOLAR DISC 2 SUNSPOT GROUPS 
WERE OBSERVED, 1 SMALL, AND 1 REACHED MIDDLE SIZE AT 4-6.11. 

 NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY WAS ON LOW LEVEL. LIKE-
LY  WEEKLY  AVERAGE VALUE OF THE RELATIVE SUNSPOT NUMBER IN THE
INTERNATIONAL SYSTEM (old) FOR NEXT WEEK IS W = 020+10/-10. 

 FLARE ACTIVITY WAS AT LOW AND VERY LOW LEVEL. 28 SOLAR FLARE OF 
LOW X-RAY CLASS CLASS "C", 73-CLASS "B", AND 2 CORONAL MASS EJEC-
TIONS (2, 8.11) HAVE BEEN OBSERVED.

 FROM 5.11/1350 UT, THE EARTH IS IN THE "-" SECTOR OF THE INTERPLANETA-
RY MAGNETIC FIELD. THE FOLLOWING THE NEXT SECTOR BOUNDARY "-/+" IT CAN 
BE EXPECT 14.11.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT BEGUN 
5.11/1250 AND OBSERVED 5 - 06.11.  
 
NEXT WEEK THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS 
ORBIT IS NOT EXPECTED.

ALL DAYS QUITE AND UNSETTLED GEOMAGNETIC CONDITION WAS OBSERVED. 

NEXT WEEK THE MOST PROBABLY QUIET AND UNSETTLED GEOMAGNETIC CON-
DITION WILL BE OBSERVED.
