SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 09/2330Z JUNE 2009 BY IPS RADIO AND SPACE SERVICES
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: 69/3
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 68/2 68/2
COMMENT: Solar wind speed at the ACE spacecraft remained low
merging of the IMF and geomagnetic fields was 10-14UT. The new
region AR1020 (N22E00) numbered 9th June is a simple beta magnetic
configuration and unlikely to flare. X-ray activity at the GOES
spacecraft remains very low. Solar activity is expected to stay
at very low levels for at least the next 3 days.

2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 09 Jun: Quiet
Estimated Indices 09 Jun : A K

Observed Regional daily pc3 Indices 09 Jun :
Darwin 0 (Quiet)
Townsville 0 (Quiet)
Learmonth 0 (Quiet)
Alice_Springs 0 (Quiet)
Camden 0 (Quiet)
Gnangara 0 (Quiet)
Canberra 0 (Quiet)
Hobart 0 (Quiet)
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 Space Environment Research Center, Japan.

COMMENT: Geomagnetic activity remained at quiet levels today.
Quiet levels are expected for the next three days with the possibility
of some Unsettled periods in the next 24hrs on 10 June.

4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY
Date T index
09 Jun 8
Observed Australian Regional MUFs
Equatorial PNG/Niue Region:
Mostly near predicted monthly values,
Northern Australian Region:
Near predicted monthly values.
Southern Australian and New Zealand Region:
Near predicted monthly values during local day,
Enhanced by 25% during local night.
Antarctic Region (Casey/Scott Base/Davis/Mawson):
Near predicted monthly values over the UT day.
Predicted Monthly T index for June: 5
4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
10 Jun 5 near predicted monthly values
11 Jun 5 Near predicted monthly values
12 Jun 5 Near predicted monthly values
COMMENT: HF conditions are expected to remain mostly normal across
Aust/NZ regions for the next three days. Equatorial regions expected
to remain dynamic but averaging to predicted monthly median MUFs.
Possibility of some ionospherc disturbance in the Southern regions
in next 24hrs from possible Unsettled geomagnetic activity, due
to a recurrent mild solar wind stream.
