Weekly Bulletin on Solar and Geomagnetic Activity
Highlights on 07 - 13.10.2013,
Forecast on 14 - 21.10.2013,
Carrington Rotation 2142 (28.14.09.2013)

SUNSPOT-FORMING ACTIVITY OF THE SUN REMAINED AT THE AVERAGE LEVEL.
WEEKLY, THE AVERAGE OF SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM
WAS MADE W=066+17/-20. ON THE VISIBLE SOLAR DISK CONSTANTLY THERE
WERE 4 - 8 SUNSPOT GROUPS ONE OF WHICH AR11861 (S13L164, Sp max =
380 m.v.h.). THE MODERATE SIZE, THE QUITE.

NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY IS EXPECTED TO BE THE AVE-
RAGE LEVEL. THE CALCULATED MOST LIKELY WEEKLY AVERAGE VALUE OF SUN-
SPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR THE NEXT WEEK IS EXPEC-
TED W = 050+20/-20.

FLARE ACTIVITY WAS FOR AT A AVERAGE LEVEL ON 9, 11 AND 13.10 AND
THE LOW - IN OTHER DAYS. DURING THE CONSIDERED PERIOD 8 DSF WERE
OBSERVED. BY SOHO AND STEREO CORONOGRAPHS DATA THERE WERE OBSERVED
42 CME FROM WHICH SIX WERE THE "PARTIAL HALO II" TYPE.

NEXT WEEK THE LEVEL OF THE FLARE ACTIVITY IS EXPECTED AT THE LOW AND
THE VERY LOW.

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

The last two were one on previous solar rotation.
R - solar rotations; KP - KIT PEAK solar observatory;
EE-date of possible geomag. disturbance in the Earth's environment.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT VERY HIGH
LEVEL BEGAN 12.10/1520 UT AND WERE OBSERVED ON OCTOBER 12 ONLY.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT VERY HIGH

DISTURBANCE FROM FILAMENT EJECTION AT OCTOBER 5 REACHED ON ENVIRON-
MENT SI-8.10/2023 UT AND CAUSED THE MINOR MAGNETIC STORM 8-9 OCTOBER
(G1, Ams=34, dur. =12 h. ) ACCORDING TO IZMIRAN DATA AND (G1, Ams=41,
dur.=18 h.) ACCORDING BOULDER SWPC CENTRE DATA. IN OTHER DAYS GEOMAG-
NETIC CONDITION CHANGED FROM UNSETTLED TO QUIET.

NEXT WEEK THE GEOMAGNETIC SITUATION IS EXPECTED QUIET AND UNSETTLED
ALL DAYS. HOWEVER 14 - 15.10 GROWTH OF GEOMAGNETIC DISTURBANCE IS POS-
SIBLE AT PASS BY EARTH OF THE HIGH-SPEED STREAM SOLAR WIND FROM NEAR
EQUATORIAL CORONAL HOLE. PROBABILITY MAGNETIC STORM ABOUT 20%.

THE GEOMAGNETIC SITUATION CHANGED FROM UNSETTLED TO QUITE ALL PERIOD.

NEXT WEEK THE GEOMAGNETIC CONDITION IS EXPECTED QUIET AND UNSETTLED.
