Weekly Bulletin on Solar and Geomagnetic Activity
Highlights on 12 - 18.10.2015,
Forecast on 19 - 26.10.2015,
Carrington Rotation 2169 (04,57.10.2015)

SUNSPOT-FORMING ACTIVITY OF THE SUN REMAINED AT THE MIDDLE LEVEL.
ESTIMATED, WEEKLY AVERAGE VALUE OF THE RELATIVE SUNSPOT NUMBER IN
THE INTERNATIONAL SYSTEM (old) WAS W = 38+11/-9 (Wn=62+17/-14). ON
THE VISIBLE SOLAR DISK HAVE BEEN OBSERVED 4-5 SMALL, QUITE SUNSPOT
GROUPS.

THE MIDDLE LEVEL OF THE SUNSPOT-FORMING ACTIVITY IS EXPECTED ON
THE NEXT WEEK. AS ESTIMATED, THE MOST LIKELY WEEKLY AVERAGE VALUE
OF THE RELATIVE SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR THE
NEXT WEEK IS W = 040+20/-10.

FLARE ACTIVITY WAS AT THE MIDDLE LEVEL AT 15 - 17.10 AND THE LOW -
IN OTHER DAYS. THERE WERE THREE SOLAR FILAMENT EJECTION OCCURREN-
CES THROUGH THE PERIOD. ACCORDING TO THE DATA FROM SOHO AND STEREO
CORONOGRAPHS >24 CMEs HAVE BEEN OBSERVED.

NEXT WEEK FLARE ACTIVITY IS EXPECTED ON THE LOW AND AVERAGE LEVELS.

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

On the last rotation the last two CH were one.
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.

15.10/07 - 18.10/1530 UT ON THE EARTH WAS IN "-" SECTOR OF THE INTER-
PLANETARY MAGNETIC FIELD. THE FOLLOWING SECTOR BOUNDARY +/- EARTH HAS

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT WAS BE-
GINNING AT 08.10/0935 UT AND WAS OBSERVED 8 - 19.10.
THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT OF VERY
HIGH LEVEL IS EXPECTED 12 - 18.10.

GEOMAGNETIC CONDITION ALREADY BEEN OCTOBER 12-13 IN A MINOR MAGNETIC
STORM (G1, Ams= 29, dur.= 27 h.) ACCORDING TO THE CENTER IN BOULDER
DATA. ACCORDING IZMIRAN DATA, IT WAS 9 hour SUBSTORM INTENSITY (G1).
WITHIN 5 hours 13-14.10, START THE NEXT MINOR MAGNETIC STORM (G1, Ams
= 33, dur.= 21 h.) According to Boulder DATA and (G0, Ams = 27, dur.=
18 h.) ACCORDING IZMIRAN DATA. RESPONSIBILITY FOR THESE GEOMAGNETIC
DISTURBANCE STEEL SOLAR WIND HIGH STREAM FROM A VERY LARGE CORONAL HO-
LE OF NORTHERN HEMISPHERE AND DISTURBANCES FROM SOLAR FILAMENT EJECTI-
ONS 7 - 9.10. 18.10 THE 9-hour SUBSTORM G1 YAVE BEEN OBSERVED. IN THE
REMAINING DAYS THE GEOMAGNETIC CONDITION WAS UNSETTLED.

NEXT WEEK THE GEOMAGNETIC CONDITION IS EXPECTED ACTIVE 21-22.10 WHEN
THE EARTH PASSES THE HIGH-SPEED STREAM OF THE SOLAR WIND FROM NORTHERN
CORONAL HOLES. PROBABILITY OF THE MAGNETIC STORM LESS THAN 10%.
