Weekly Bulletin on Solar and Geomagnetic Activity
Highlights on 09 - 15.03.2015,
Forecast on 16 - 23.03.2015,
Carrington Rotation 2161 (27,93.03.2015)
SUNSPOT-FORMING ACTIVITY OF THE SUN REMAINED AT THE AVERAGE LE-
VEL, BUT IN THE LAST 2 DAYS OF THE PERIOD - ALREADY ON THE LOW.
ESTIMATED, WEEKLY AVERAGE VALUE OF THE RELATIVE SUNSPOT NUMBER
IN THE INTERNATIONAL SYSTEM WAS MADE W=031+21/-14. ON THE VISIB-
LE DISK OF THE SUN CONSTANTLY OBSERVED 2-1 SMALL SUNSPOT GROUPS.
ON THE VISIBLE DISK OF THE SUN WERE CONSTANTLY OBSERVED FROM 1
TO 5 SUNSPOT GROUPS ONE OF WHICH WAS AVERAGE SIZE. AR12297- SUN-
SPOT GROUP IS FLARE-ACTIVE:
AR12297 (S17L196, CMP 13.03. 2014; Sp=420 msh)
XRI=6.02 on 14.03; X/1+M/15, from which 4 large;
PFR1 (1st period of large flares realization): 53 h. 5-7.03(M/4);
PFR2 - 72 h. 9-12.03 (X/1+M/11).
NEXT WEEK EXPECTED THE LOW LEVELS OF SUNSPOT ACTIVITY. ESTIMA-
TED, MOST LIKELY WEEKLY AVERAGE VALUE OF RELATIVE SUNSPOT NUM-
BER IN THE INTERNATIONAL SYSTEM FOR THE NEXT WEEK IS EXPECTED
W = 030+10/-20.
FLARE ACTIVITY WAS AT THE HIGH LEVEL ON 9 - 11 MARCH, AT THE
MIDDLE LEVEL - 12-15.03. BY DATA OF CORONOGRAPHS SOHO AND STEREO
WERE OBSERVED >35 CME FROM WHICH ONE WAS "HALO" TYPE, ONE -"PAR-
TIAL HALO III" TYPE AND THREE - "PARTIAL HALO II" TYPE.
