Weekly Bulletin on Solar and Geomagnetic Activity
                  Highlights on 15 - 21.06.2020,
                   Forecast on 22 - 29.06.2020,
   Carrington Rotations 2231, 2232 (21,88.05; 18,08.06.2020)   
             Earth out of ecliptic (-1.8 - -1.2) deg. 
             (S25 - N25 is zone of geoeffectiveness)

THE SUNSPOT-FORMING ACTIVITY REMAINED ON VERY LOW LEVEL. THE 
SUN's VISIBLE DISK  WAS SPOTLESS ALL DAYS  EXCEPT 15.06 (128 
SPOTLESS DAYS AT 2020). ESTIMATED, MOST LIKELY WEEKLY AVERAGE 
VALUE OF THE RELATIVE SUNSPOT NUMBER IN THE INTERNATIONAL SYS-
TEM (old) FOR PERIOD W =1+6/-1 (Wn= 1+10/-1).  

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

 FLARE ACTIVITY WAS AT VERY LOW LEVEL. 3 SOLAR FLARE OF VERY 
LOW X-RAY CLASS "A" HAVE BEEN OBSERVED.

ON THE VISIBLE SOLAR DISK THE FOLLOWING CORONAL HOLES WERE OBSERVED:

* - low geoeffectivity, the substorms with duration <6 h. only.
Sch - CH area in % solar hemisphere near the central meridian on 
https://www.solarmonitor.org/; n/d - no data; R - solar rotations; 
EE-date of possible geomagnetic disturbance in the Earth's environment. 
G(0-5)-geoeffectivity in last solar rotation on the middle latitudes. 
A-active geomagnetic condition.

 FROM 17.06/0620 UT, THE EARTH IS IN THE "+" SECTOR OF THE INTERPLANE-
TARY MAGNETIC FIELD.  THE FOLLOWING THE NEXT SECTOR BOUNDARY "+/-" IT 
CAN EXPECT 22.06.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT NOT OB-
OBSERVED. 
 
NEXT WEEK THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS OR-
BIT IS NOT EXPECTED.

 THE GEOMAGNETIC CONDITION REMAINED QUITE AND UNSETTLED ALL PERIOD.

NEXT WEEK THE MOST PROBABLY QUIET AND UNSETTLED GEOMAGNETIC CONDI-
TION WILL OBSERVED.
