Weekly Bulletin on Solar and Geomagnetic Activity
                  Highlights on 13 - 19.07.2020,
                   Forecast on 20 - 27.07.2020,
    Carrington Rotation 2232, 2233 (18,08.06; 15.28.07.2020)   
             Earth out of ecliptic (-1.1 - +1.5) 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 (152 SPOTLESS DAYS AT 
2020). ESTIMATED, MOST LIKELY WEEKLY AVERAGE VALUE OF THE RELA-
TIVE SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM (old) FOR PERI-
OD W= 0 (Wn= 0).

 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", 3 SOLAR FILAMENT EJECTION (DSF)  AND 4 CORONAL 
MASS EJECTION (16 AND 17.07) HAVE BEEN OBSERVED.

NEXT WEEK THE FLARE ACTIVITY IS EXPECTED AT VERY LOW LEVEL.

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 2.07/1120 UT, THE EARTH IS IN THE "+" SECTOR OF THE INTERPLANE-
TARY MAGNETIC FIELD. THE FOLLOWING THE NEXT SECTOR BOUNDARY "+/-" IT 
CAN EXPECT 23.07.

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.
