            Carrington Rotation 2164 (21,44.05.2015)

SUNSPOT-FORMING ACTIVITY OF THE SUN WAS AT THE AVERAGE AND LOW LEVEL.
ESTIMATED, WEEKLY AVERAGE VALUE OF THE RELATIVE SUNSPOT NUMBER IN THE
INTERNATIONAL SYSTEM WAS MADE W=021+19/-07. ON THE VISIBLE SOLAR DISK
CONSTANTLY OBSERVED 4 - 2 SMALL SUNSPOT GROUPS, ALL QUITE.

 NEXT WEEK  THE AVERAGE AND LOW LEVELS OF SUNSPOT-FORMING OF ACTIVITY,
IS EXPECTED. ESTIMATED,  MOST LIKELY WEEKLY AVERAGE VALUE  OF RELATIVE
SUNSPOT NUMBER IN THE INTERNATIONAL SYSTEM FOR THE NEXT WEEK IS EXPEC-
TED W = 030+10/-20.

 FLARE ACTIVITY WAS AT THE LOW LEVEL ONLY MAY, 27  AND THE VERY LOW IN
OTHER DAYS. ONE SOLAR FILAMENT EJECTIONS OCCURRENCE THROUGH THE PERIOD.
BY DATA OF CORONOGRAPHS SOHO AND STEREO WERE OBSERVED >22 CME FROM WHICH
ONE WAS THE "PARTIAL HALO II" TYPE (angular width 90 - 180 degrees).

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

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

The last two, perhaps, make one enormous CH.
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.
