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 AND ONLY 20.03 - ON THE LOW LEVEL. ESTIMATED, WEEKLY AVERAGE
VALUE OF THE RELATIVE SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM
WAS MADE W = 033+20/-17. ON THE VISIBLE DISK OF THE SUN CONSTANT-
LY OBSERVED 4-2 SUNSPOT GROUPS, ONE OF WHICH WAS AVERAGE SIZE.
AR12297- ITS FINAL EVOLUTIONARY FORMULA:
AR12297 (S17L196, CMP 13.03. 2014; Spmax = 420 msh);
XRI=6.26 - a flare index; X/1+M/17, from which 4 large flares;
PFER 1-(53 h.) 5-7.03 (M/4)-the 1st period of flare energy release;
PFER 2 - (72 h.) 9-12.03 (X/1+M/11) - the second PFER.

NEXT WEEK EXPECTED THE AVERAGE AND THE LOW LEVELS OF SUNSPOT ACTI-
VITY. ESTIMATED, MOST LIKELY WEEKLY AVERAGE VALUE OF RELATIVE SUN-
SPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR THE NEXT WEEK IS EX-
PECTED W = 030+10/-20.

FLARE ACTIVITY WAS AT THE MIDDLE LEVEL ON 17-18 MARCH, AT THE LOW
LEVEL - 18 - 22.03. EJECTIONS OF SOLAR FILAMENTS WERE OBSERVED 16,
18 AND 22.03. BY DATA OF CORONOGRAPHS SOHO AND STEREO WERE OBSER -
VED 20 CME FROM WHICH ONE WAS -"PARTIAL HALO III".

The last three CH perhaps one, were formed on a visible disk of the
Sun at March, 16 - 18.
R - solar rotations; KP - KIT PEAK solar observatory;
EE-date of possible geomag. disturbance in the Earth's environment.
G - geoeffectivity in last solar rotation;
A-active geomagnetic condition.

AFTER 14.03/22 UT THE EARTH IS IN "-" SECTOR OF THE INTERPLANETARY
MAGNETIC FIELD. THE FOLLOWING SECTOR BOUNDARY -/+ THE EARTH HAS TO
PASS 23.03.

MINOR PROTON EVENTS WERE REGISTERED FROM SOLAR FLARE M1.2 15/2242 UT:

Pr>10 MeV: to~16/0000 UT; tmax - 09 UT; te-15 UT;

THE GREATER THEN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT OF VERY
HIGH LEVEL BEGAN 18.03/1515 UT AND WAS OBSERVED ON MARCH, 18 - 22.03.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT OF VERY
HIGH LEVEL IS EXPECTED 23 - 26.03.

THE GEOMAGNETIC CONDITIONS WERE DISTURBED 17 - 20, 22.03. SEVERE MAG-
NETIC STORM (G5, Ams=117, dur. = 24 h.) - THE BIGGEST IN THE CURRENT
SOLAR CYCLE, BY DATA OF IZMIRAN 17 - 18.03 IS REGISTERED AFTER ARRIVAL
DISTURBANCE FROM FLARE C9.1/1F 15.03/0115 UT WITH "HALO" TYPE CME. AF-
TER IT, IN 6 HOURS, 18 - 19.03 MINOR the MAGNETIC STORM IS NOTED (G1,
Ams= 38, dur.= 18 h.) AND IN 15 HOURS (20.03) ONE MORE MINOR MAGNETIC
STORM (G0, Ams=24, dur.=30 h.) IS NOTED, AND 22.03 -SUBSTORM OF INTEN-
SITY (G1, dur. 6 h.) WAS REGISTERED ALSO.
ACCORDING TO THE CENTRE IN BOULDER 17-19.03 ONE LONG MAGNETIC STORM
WAS OBSERVED (G4, Ams = 83, dur. = 60 h.), AFTER WHICH IN 6 HOURS (19
- 20.03) MINOR MAGNETIC STORM FOLLOWED (G1, Ams= 33, dur.= 12 h.) AND
AT THE END OF THE DAY 20 AND 21.03 ONE MORE MINOR MAGNETIC STORM (G1,
Ams= 25, dur.= 12 h.), AND 22.03 IT IS NOTED SUBSTORM OF G1 INTENSITY,
dur. 9 h. ALL THESE ADDITIONAL GEOMAGNETIC DISTURBANCES WERE FED WITH
FLARES IN AR12297 AND SOLAR FILAMENT EJECTIONS 17-18.03. ONLY 16 AND
21.03 GEOMAGNETIC CONDITIONS WAS UNSETTLED.

23 - 24 MARCH THE EARTH WILL PASS THE HIGH-SPEED STREAMS OF THE SOLAR
WIND FROM NEAR EQUATORIAL CORONAL HOLES. 26.03 DISTURBANCE FROM SOLAR
FILAMENT EJECTIONS ON THE CENTRAL ZONE OF THE SUN 22.03 WILL APPROACH
THE EARTH. THEREFORE THESE DAYS GROWTH OF GEOMAGNETIC DISTURBANCE IS
POSSIBLE. PROBABILITY OF MAGNETIC STORMS ABOUT 30%. IN OTHER DAYS GEO-
MAGNETIC CONDITIONS UNSETTLED AND QUIET IS EXPECTED.
