FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 09 JUNE AND FORECAST FOR 10 JUNE - 12 JUNE
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 09 Jun: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 09 Jun: 67/0
1B. SOLAR FORECAST
10 Jun 11 Jun 12 Jun
Activity Very low Very low Very low
Fadeouts None expected None expected None expected
10.7cm/SSN 68/2 71/6 71/6
COMMENT: Solar activity was Very Low during the UT day, 9 June.
There are currently no numbered sunspot regions on the visible
disk. For the next 3 UT days, 10-12 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,
9 June, in LASCO C2 imagery up to 09/1848 UT. During the last
24 h, the solar wind speed varied between 360 km/s and 320 km/s,
currently around 340 km/s. The IMF Bt varied between 1-4 nT.
The Bz component of IMF varied between +/-2 nT. The outlook for
10-11 June is for the solar wind speed to remain at nominal values
then become moderately enhanced on the UT day 12 June due to
the influence of a recurrent coronal hole.

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.

2B. MAGNETIC FORECAST
Date Ap Conditions
10 Jun 4 Quiet
11 Jun 4 Quiet
12 Jun 8 Quiet to Unsettled, with the chance of isolated
Active periods
COMMENT: Geomagnetic conditions across the Australian region
on UT day 9 June were at Quiet levels. Geomagnetic activity is
expected to be Quiet on the next two UT days, 10-11 June, then
become Quiet to Unsettled, with a chance of isolated Active periods,
on UT day 12 June due to the influence of a recurrent coronal
hole.

4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
10 Jun 0 Near predicted monthly values
11 Jun 0 Near predicted monthly values
12 Jun 10 Near predicted monthly values
COMMENT: On UT day 9 June, MUFs were mostly near predicted monthly
values for AUS/NZ regions. Expect mostly near predicted monthly
values for the next two UT days, 10-11 June. On UT day 12 June,
MUFs are expected to be mostly near predicted monthly values
but may become enhanced due to expected Unsettled geomagnetic
activity levels.
