Weekly Bulletin on Solar and Geomagnetic Activity
Highlights on 25.06 - 02.07.2012,
Forecast on 03 - 10.07.2012,
Carrington Rotation 2125 (21,62.06.2012)

SUNSPOT ACTIVITY WAS ON THE LOW LEVEL AT 25-26 JUNE AND AFTER - ON
THE AVERAGE. WEEKLY, THE AVERAGE OF SUNSPOT NUMBER IN THE INTERNATI-
ONAL SYSTEM FOR THE PERIOD WAS MADE W = 044 +38/-36. ON THE VISIBLE
DISK OF THE SUN CONSTANTLY WERE PRESENT FROM 1 TO 5 SUNSPOT GROUP
ONE OF WHICH SINCE WAS BIG SIZE.

AR11515 (S16L205, Sp=850 Э.Ф.а. ON 30.06)- appeared from East limb at
the end of the 25.06 as sunspot group of the average size. Probably
makes the complex of active regions with AR11514. After 30.06 to 1.07
it area increased in 2.5 times (new magnetic flux emergence), than
created reconditions of sharp increase of flare activity since June 3.

NEXT WEEK THE LEVEL OF SUNSPOT ACTIVITY IS EXPECTED TO BE AVERAGE.
THE CALCULATED MOST LIKELY WEEKLY AVERAGE VALUE OF SUNSPOT NUMBER IN
THE INTERNATIONAL SYSTEM FOR THE NEXT WEEK W=050+25/-10.

FLARE ACTIVITY WAS AT AVERAGE LEVEL 28-30.06 and 1.07, IN OTHER DAYS
- AT LOW LEVEL. BY DATA OF SOHO AND STEREO CORONOGRAPHS FOR THE PERI-
OD IT WAS OBSERVED MORE THAN 48 CME AMONG WHICH 5 WAS SUCH AS "PARTI-
AL HALO II" TYPE.

NEXT WEEK FLARE ACTIVITY IS EXPECTED ON AVERAGE AND HIGH LEVELS. LAR-

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT VERY HIGH
LEVEL WAS OBSERVED AFTER 1.07/1320 UT.

THE GREATER THAN 2 MeV ELECTRON FLUX AT GEOSTATIONARY ORBIT VERY HIGH
LEVEL IS EXPECTED 2 - 9.07, AS A RESULT OF RECURRENT GEOMAGNETIC DIS-
TURBANCE FROM SOLAR CORONAL HOLE.

LAST WEEK THE GEOMAGNETIC CONDITIONS WAS UNSETTLED AND QUIET TO THE
FIRST HALF ON JUNE 30 WHEN EARTH WAS INCLUDED INTO THE HIGH-SPEED
STREAM OF THE SOLAR WIND FROM VERY BIG CORONAL HOLE. GEOMAGNETIC OB-
SERVATORY REGISTERED THE MINOR MAGNETIC STORM (G0, Ams=24, dur.=15 h.)
ACCORDING IZMIRAN DATA AND (G0, Ams=26, dur.= 24 h.) ACCORDING TO THE
CENTER IN BOULDER.

NEXT WEEK THE GEOMAGNETIC CONDITIONS IS EXPECTED UNSETTLED AND QUIET.
