SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 07/2330Z AUGUST 2008 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 07 AUGUST AND FORECAST FOR 08 AUGUST - 10 AUGUST
STATUS INDICATORS SOL:GREEN MAG:** YELLOW ** ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 07 Aug: Very low
Flares: None
Observed 10.7 cm flux/Equivalent Sunspot Number for 07 Aug: 66/0
1B. SOLAR FORECAST
08 Aug 09 Aug 10 Aug
Activity Very low Very low Very low
Fadeouts None expected None expected None expected
10.7cm/SSN 66/0 66/0 66/0
COMMENT: The solar disk is spotless. The solar wind ranged from
about 330 to 380 km/s over the past 24 hours. The solar wind
speed is expected to begin increasing later on the 8th or 9th
due to the high speed wind stream associated with a recurrent
coronal hole.

Observed Regional daily pc3 Indices 07 Aug :
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.
Estimated AFr/Ap Indices 07 Aug : A
Fredericksburg 4
Planetary 4
Observed AFr/Ap Indices 06 Aug : A K

2B. MAGNETIC FORECAST
Date Ap Conditions
08 Aug 10 Mostly quiet to unsettled. Possibility of isolated
active periods later.
09 Aug 20 Mostly unsettled to active. Possibility of isolated
minor storm periods.
10 Aug 14 Unsettled with isolated active periods.
COMMENT: IPS Geomagnetic Warning 9 was issued on 6 August and
is current for interval 7-9 August. Activity is expected to begin
increasing later on the 8th due to the effects of a high speed
wind stream associated with a recurrent coronal hole.
