Weekly Bulletin on Solar and Geomagnetic Activity
              Highlights on 15- 21.01.2018,
               Forecast on 22 - 29.01.2018,
Carrington Rotation 2199, 2200 (30,94.12.2017; 27,28.01.2018)
          Earth above the ecliptic (0.0 - -0.7) deg. 
             (S30 - N30 is geoeffectiveness zone)

 SUNSPOT-FORMING ACTIVITY WAS ON THE VERY LOW LEVEL AND THE SUN 
WAS SPOTLESS ALL PERIOD (15 DAYS IN 2018). THE ESTIMATED, MOST 
LIKELY WEEKLY AVERAGE VALUE OF THE RELATIVE SUNSPOT NUMBER  IN 
THE INTERNATIONAL SYSTEM (old) FOR THE PERIOD W= 000 (Wn= 000). 

 NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY  WITH HIGH PROBABILITY 
WILL BE ON THE VERY LOW LEVEL. WITH A GRATE PROBABILITY, WE ARE 
WAITING FOR THE NEXT WEEK  OF THE SPOTLESS SUN.  LIKELY  WEEKLY 
AVERAGE VALUE OF THE RELATIVE SUNSPOT NUMBER IN THE INTERNATIO-
NAL SYSTEM (old) FOR THE NEXT WEEK IS W = 010+10/-10.  

THE FLARE ACTIVITY WAS AT THE VERY LOW LEVEL. NO EJECTION OF SO-
LAR FILAMENT AND TWO CORONAL MASS EJECTION HAVE BEEN OBSERVED.

Sch - CH Square in Mm**2 (in square megameters) near the central meri-
dian on http://sdowww.lmsal.com/suntoday/; n/d - no data;
R - solar rotations; EE-date of possible geomag. disturbance in the 
Earth's environment. G(0-5)-geoeffectivity in last solar rotation on
the middle latitudes. A-active geomagnetic condition.

AFTER 18.01/17 UT THE EARTH IS IN "-" SECTOR OF THE INTERPLANETARY MAG-
NETIC FIELD. NEXT SECTOR BOUNDARY -/+ EARTH SHOULD BE PASSED 0N 28.01.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT HAS BE-
GUN 23.01/1830 UT AND OBSERVED 23 - 24.01.
 
NEXT WEEK THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS OR-
BIT IS NOT EXPECTED.

GEOMAGNETIC CONDITION WAS UNSETTLED AND QUIET IN THE PERIOD.  

NEXT WEEK THE GEOMAGNETIC CONDITION IS EXPECTED UNSETTLED AND  QUIET.
