SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 08/2330Z SEPTEMBER 2009 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 08 SEPTEMBER AND FORECAST FOR 09 SEPTEMBER - 11 SEPTEMBER
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 08 Sep: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 08 Sep: 69/3
1B. SOLAR FORECAST
09 Sep 10 Sep 11 Sep
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.
The visible disk remains spotless. Solar wind speed gradually
decreased from 350 to 310 km/s over the UT day today. The Bz
component of the interplanetary magnetic field stayed close to
the normal value (between +/-3 nT) almost the whole day today.
Solar activity is expected to stay at very low levels for the
next 3 days.

2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 08 Sep: Quiet
Estimated Indices 08 Sep : A K

Darwin 2 12100002
Townsville 5 12211122
Learmonth 1 11000100
Canberra 0 10000001
Hobart 2 11110111

Observed Regional daily pc3 Indices 08 Sep :
Darwin 0 (Quiet)
Townsville 0 (Quiet)
Learmonth 0 (Quiet)
Alice_Springs 0 (Quiet)
Gnangara 0 (Quiet)
Canberra 0 (Quiet)
Hobart 6 (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 Sep : A
Fredericksburg 3
Planetary 8
Observed AFr/Ap Indices 07 Sep : A K

2B. MAGNETIC FORECAST
Date Ap Conditions
09 Sep 3 Quiet
10 Sep 3 Quiet
11 Sep 3 Quiet
COMMENT: The geomagnetic field was quiet over the last 24 hours.
Similar conditions are expected for the next three days.
-----------------------------------------------------------
3A. GLOBAL HF PROPAGATION SUMMARY
Latitude Band
Date Low Middle High
08 Sep Normal Normal Normal-fair
PCA Event : No event.
3B. GLOBAL HF PROPAGATION FORECAST
Latitude Band
Date Low Middle High
09 Sep Normal Normal Normal
10 Sep Normal Normal Normal
11 Sep Normal Normal Normal
COMMENT: HF conditions remained mostly normal on most
locations on 08 September with some periods of degradations
at high latitude and presence of sporadic E-layer on low
latitudes. Mostly normal HF conditions may be expected on
most locations for the next three days as no significant
variation in the ionospheric conditions is expected during
this period.

4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
09 Sep -4 near predicted monthly values
10 Sep -4 near predicted monthly values
11 Sep -4 near predicted monthly values
COMMENT: HF conditions remained mostly normal across Aus/NZ
