SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 08/2330Z JUNE 2009 BY IPS RADIO AND SPACE SERVICES
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: 69/3
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 69/3
COMMENT: Solar activity was very low over the last 24 hours.
Solar wind speed gradually decreased from 380 to 310 km/s
during the day. The Bz component of the interplanetary
magnetic field stayed close to the normal value for most
parts of the day. Solar activity is expected to stay at
very low levels for the next 3 days. A new region 1020(N22E07)
has been numbered today.

2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 08 Jun: Quiet
Estimated Indices 08 Jun : A K
Australian Region 2 11111101
Darwin 1 11101001
Townsville 5 12112122
Learmonth 2 11111100
Camden 0 11000000
Canberra 0 00000000
Hobart 2 11111100
Casey(Ant) 4 22211111
Observed Regional daily pc3 Indices 08 Jun :
Darwin 0 (Quiet)
Townsville 0 (Quiet)
Learmonth 2 (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 08 Jun : A
Fredericksburg 3
Planetary 4
Observed AFr/Ap Indices 07 Jun : A K

2B. MAGNETIC FORECAST
Date Ap Conditions
09 Jun 4 Quiet
10 Jun 6 Mostly quiet, some unsettled periods possible.
11 Jun 4 Quiet
COMMENT: Geomagnetic activity remained at quiet levels today.
Similar level of activity is expected for the next three days
with the possibility of some unsettled periods on 10 June.

3A. GLOBAL HF PROPAGATION SUMMARY
Latitude Band
Date Low Middle High
08 Jun Normal Normal Normal
PCA Event : No event.
3B. GLOBAL HF PROPAGATION FORECAST
Latitude Band
Date Low Middle High
09 Jun Normal Normal Normal
10 Jun Normal Normal Normal-fair
11 Jun Normal Normal Normal
COMMENT: HF conditions were mostly normal on most locations
today although sporadic E-layers and spread-F conditions
were also observed at times. Some degradations at high
latitudes were also observed today. HF conditions are expected
to remain mostly normal on most locations for the next three
days with some possibility of periods of degraded conditions
on high latitudes on 10 June.

Equatorial PNG/Niue Region:
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 15% 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
09 Jun 6 Near predicted monthly values to enhanced 10%.
10 Jun 3 near predicted monthly values
11 Jun 6 Near predicted monthly values to enhanced 10%.
COMMENT: HF conditions are expected to remain mostly normal
on most locations across Aus/NZ regions for the next three
days with small possibility of some periods of minor degradations
in the Southern Aus/NZ regions on 10 June.
