Weekly Bulletin on Solar and Geomagnetic Activity
                  Highlights on 23 - 29.11.2020,
                    Forecast on 30.11 - 06.12.2020,
    Carrington Rotations 22372238(28,6.11; 25,94.12.2020)   
                Earth out of ecliptic (3.1 - 2.7) deg. 
               (S29 - N31 is zone of geoeffectiveness)

THE SUNSPOT-FORMING SOLAR ACTIVITY REMAINED ON MIDDLE LEVEL. ES-
TIMATED, MOST LIKELY WEEKLY AVERAGE VALUE OF THE SUNSPOT NUMBER 
IN THE INTERNATIONAL SYSTEM (old) FOR PERIOD W = 32+18/-10 (Wn= 
53+29/-16). ON THE VISIBLE DISK OF THE SUN ONE LARGE (FIRST IN 
THE CURRENT CYCLE) AND FOUR MINOR SUNSPOT GROUPS WERE OBSERVED. 
THE LARGE AND 2 MINOR SUNSPOT GROUPS FORMED A COMPLEX OF ACTIVE 
REGIONS IN COORDINATES (S23-S16, L359-L349).

NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY WAS MIDDLE. LIKELY WEEK-
LY AVERAGE VALUE OF THE RELATIVE SUNSPOT NUMBER IN THE INTERNA-
TIONAL SYSTEM (old) FOR NEXT WEEK IS W=040+20/-20. 

 FLARE ACTIVITY  WAS AT MIDDLE, LOW AND VERY LOW LEVELS. SOLAR 
FLAREM4.4 X-RAY CLASS OCCURENCED BEHIND E-LIMB IN ACTIVE REGION
THAT WILL GO AT 2.11. 14 SOLAR FLARE OF LOW X-RAY CLASS "C", 31
-CLASS "B",  AND 9 CORONAL MASS EJECTIONS (23 - 27, 29.11) HAVE 
BEEN OBSERVED.

EE-date of possible geomagnetic disturbance in the Earth's environment. 
G(0-5)-geoeffectivity in last solar rotation on the middle latitudes.

 FROM 17.11/1350 UT, THE EARTH IS IN THE "+" SECTOR OF THE INTERPLANETA-
RY MAGNETIC FIELD. THE FOLLOWING THE NEXT SECTOR BOUNDARY "-/+" IT CAN 
BE EXPECT 4.12.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT BEGUN 
22.11 AND OBSERVED 22-29.11.  
 
NEXT WEEK THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS 
ORBIT IS EXPECTED 30.11 - 2.12.

ALL DAYS THERE ARE UNSETTLED AND QUITE GEOMAGNETIC CONDITION HAVE 
BEEN OBSERVED. 

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