Weekly Bulletin on Solar and Geomagnetic Activity
Highlights on 16 - 22.03.2015,
Forecast on 23 - 30.03.2015,
Carrington Rotation 2161 (27,93.03.2015)

SUNSPOT-FORMING ACTIVITY OF THE SUN REMAINED ON THE AVERAGE LE-
VEL ALL DAYS, GRADUALLY DECREASING BY THE END OF THE PERIOD. ES-
TIMATED, WEEKLY AVERAGE VALUE OF THE RELATIVE SUNSPOT NUMBER IN
THE INTERNATIONAL SYSTEM WAS MADE W =062+14/-18. ON THE VISIBLE
DISK OF THE SUN CONSTANTLY OBSERVED 8 - 5 SUNSPOT GROUPS, ONE OF
WHICH WAS AVERAGE SIZE.

NEXT WEEK EXPECTED THE AVERAGE AND THE LOW LEVELS OF SUNSPOT AC-
TIVITY. ESTIMATED, MOST LIKELY WEEKLY AVERAGE VALUE OF RELATIVE
SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR THE NEXT WEEK IS
EXPECTED W = 030+20/-20.

FLARE ACTIVITY WAS AT THE LOW LEVEL. EJECTIONS OF SOLAR FILAMENTS
WERE OBSERVED 23 AND 27.03. BY DATA OF CORONOGRAPHS SOHO AND STE-
REO WERE OBSERVED > 38 CME FROM WHICH ONE WAS "HALO" TYPE AND TWO
-"PARTIAL HALO II" TYPE.

NEXT WEEK FLARE ACTIVITY IS EXPECTED AT THE AT THE LOW AND THE
AVERAGE (IMPROBABLE) LEVELS.

EE-date of possible geomag. disturbance in the Earth's environment.
G - geoeffectivity in last solar rotation;
A-active geomagnetic condition.

FROM 26.03/1430 UT THE EARTH IS IN "-" SECTOR OF THE INTERPLANETARY
MAGNETIC FIELD. FROM 23/00 UT TILL 26.03 THE EARTH PASSED "+" SECTOR.
THE FOLLOWING SECTOR BOUNDARY -/+ THE EARTH HAS TO PASS 31.03.

THE GREATER THEN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT OF VERY
HIGH LEVEL BEGAN 18.03/1515 UT AND WAS OBSERVED ON MARCH, 23 - 28.03.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT OF VERY
HIGH LEVEL IS NOT EXPECTED.

ACCORDING TO IZMIRAN DATA 23.03 ARE NOTED SUBSTORM G1-INTENSITY (dur.
=6 h.), AFTER WHICH IN 6 HOURS the MINOR MAGNETIC STORM WAS REGISTERED
(G1, Ams = 26, dur.= 12 h.). ACCORDING TO CENTRE IN BOULDER THIS DAY
TWO SUBSTORMS ARE REGISTERED by G1 AND G0-INTENSITY, DURATION 6 AND 3
HOURS. IN OTHER DAYS THE GEOMAGNETIC CONDITIONS WERE UNSETTLED AND
QUIET: ON MARCH, 24-25 SEPARATE 3-HOUR SUBSTORMS (G0) WERE NOTED.

3-4 APRIL THE EARTH WILL PASS THE HIGH-SPEED STREAMS OF THE SOLAR WIND
FROM EQUATORIAL CORONAL HOLES. THEREFORE THESE DAYS GROWTH OF GEOMAG-
NETIC DISTURBANCE IS POSSIBLE. PROBABILITY OF MAGNETIC STORMS ABOUT 40%.
IN OTHER DAYS GEOMAGNETIC CONDITIONS UNSETTLED AND QUIET IS EXPECTED.
