FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 08 JUNE AND FORECAST FOR 09 JUNE - 11 JUNE
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 08 Jun: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 08 Jun: 68/2
1B. SOLAR FORECAST
09 Jun 10 Jun 11 Jun
Activity Very low Very low Very low
Fadeouts None expected None expected None expected
10.7cm/SSN 69/3 69/3 71/6
COMMENT: Solar activity was Very Low during the UT day, 8 June.
There are currently no numbered sunspot regions on the visible
disk. For the next 3 UT days, 9-11 June, solar activity is expected
to remain at Very Low levels with a slight chance for C-class
flares. No Earth-directed CMEs were observed during the UT day,
8 June, in LASCO C2 imagery up to 08/2012 UT. During the last
24 h, the solar wind speed decreased from 380 km/s to currently
around 355 km/s. The IMF Bt varied between 1-5 nT. The Bz component
of IMF varied between +/-5 nT. The outlook for 9-11 June is for
the solar wind speed to remain at nominal values.

Pc3 pulsations are high frequency (10-45 second period) variations
of the Earths magnetic field. Daily pc3-indices are the daily sum
of 20 minute pc3-indices for that station and have been shown to be
well correlated with rejection of high resolution aeromagnetic
survey flight-line data.
NOTE: Indices may have been generated from data obtained in
cooperation with the following organisations: Geoscience Australia,
University of Newcastle Space Physics Group, Australian Government
Antarctic Division and International Center for Space Weather
Science and Education, Japan.

COMMENT: Geomagnetic conditions across the Australian region
on UT day, 8 June, were mainly at Quiet levels, with an isolated
Unsettled period in the middle of the UT day in the Southern
Australian region. Geomagnetic activity is expected to be Quiet
on the UT days, 9-11 June.
