Weekly Bulletin on Solar and Geomagnetic Activity
               Highlights on 08 - 14.07.2019,
                Forecast on 15 - 22.07.2019,
          Carrington Rotation 2219 (29,5.06.2019)    
           Earth out of ecliptic (0.5 - 1.2) deg. 
          (S25 - N25 is zone of geoeffectiveness)

 THE SUNSPOT-FORMING SOLAR ACTIVITY WAS AT THE VERY LOW LEVEL. 
THE SOLAR DISC WAS SPOTLESS (124 SPOTLESS DAYS IN THE CURRENT 
YEAR). ESTIMATED, MOST LIKELY WEEKLY AVERAGE VALUE OF THE RE-
LATIVE SUNSPOT NUMBER  IN THE INTERNATIONAL SYSTEM (old) FOR 
PERIOD W =0 (Wn=0). 

 NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY  WAS ON VERY LOW LE-
VELS. THE VISIBLE SOLAR DISK EXPECTED SPOTLESS. LIKELY WEEKLY 
AVERAGE VALUE OF THE RELATIVE SUNSPOT NUMBER IN THE INTERNATI-
ONAL SYSTEM (old) FOR THE NEXT WEEK IS W=010+20/-10. 

 FLARE ACTIVITY  WAS AT THE VERY LOW LEVEL. ONE SOLAR FILAMENT 
AND ONE CORONAL MASS EJECTIONS HAVE BEEN OBSERVED.

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

 MIDDLE ARE REMAINED WITH THE "+" SIGN. THE NEXT SECTOR LIMIT OF THE 
 EARTH HAS TO PASS 24.07.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT BEGUN 
AT 10.07/1230 AND 10-14.07 HAVE BEEN OBSERVED. 
 
NEXT WEEK THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS OR-
BIT IS EXPECTED 15-16.07.

THE GEOMAGNETIC CONDITION AT MIDDLE LATITUDES 9 AND 10.07 WAS ACTIVE 
BECAUSE OF JOINT IMPACT OF DISTURBANCE FROM SOLAR FILAMENT EJECTION 
02.07 WITH VERY SLOW CORONAL MASS EJECTION AND THE HIGH-SPEED STREAM 
OF THE SOLAR WIND FROM THE CORONAL HOLE "+" POLARITY OF NORTHERN HE-
MISPHERE. IN OTHER DAYS THE GEOMAGNETIC CONDITION REMAINED QUIET AND 
UNSETTLED.

NEXT WEEK THE GEOMAGNETIC CONDITION IS MOST PROBABLE QUIET AND UNSET-
TLED.
