SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 06/2330Z OCTOBER 2003 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 06 OCTOBER AND FORECAST FOR 07 OCTOBER - 09 OCTOBER
STATUS INDICATORS SOL:GREEN MAG:* YELLOW * ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 06 Oct: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 06 Oct: 112/63
1B. SOLAR FORECAST
07 Oct 08 Oct 09 Oct
Activity Low Low Low
Fadeouts None expected None expected None expected
10.7cm/SSN 110/60 110/60 105/54
COMMENT: Solar activity remained very low today. Occasional Type
III sweep activity observed on Culgoora radiospectrograph, and
a non-correlated very weak Type II sweep observed at 0145UT.
Possibility of isolated C to M-class flares today from region
471.

2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 06 Oct: Quiet to Unsettled
Estimated Indices 06 Oct : A K
Australian Region 6 2122 2222
Darwin 1 1000 0200
Townsville 9 2222 323-
Learmonth 8 2122 323-
Canberra 7 1212 223-
Hobart 6 1211 223-
Casey(Ant) 9 3-32 21-3
Observed Regional daily pc3 Indices 06 OCT :
Townsville 0 (Quiet)
Learmonth 8 (Quiet)
Canberra 50 (Unsettled)
Hobart 64 (Active)
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.
Estimated AFr/Ap Indices 06 Oct : A
Fredericksburg 8
Planetary 12
Observed AFr/Ap Indices 05 Oct : A K
Fredericksburg 4
Planetary 9 2212 2334
2B. MAGNETIC FORECAST
Date Ap Conditions
07 Oct 18 Active
08 Oct 12 Unsettled
09 Oct 10 Quiet to Unsettled
COMMENT: Mostly quiet geomagnetic conditions were observed over
the UT day. Solar wind speed increased to over 600 km/s during
the latter half of the UT day. IMF remained mostly northward
during the UT day, with a period of strong magnitude fluctuations
towards the end of the day. Isolated active periods in the geomagnetic
field were observed at high latitudes during this time. Solar
wind speed reamins elevated under the influence of a coronal
hole at the time of report issue. Expect unsettled conditions
today with isolated active periods.

4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY
Date T index
06 Oct 85
Observed Australian Regional MUFs
Equatorial PNG Region:
Near predicted monthly values during local day.
Enhanced by 15% during local night and after
local dawn.
Northern Australian Region:
Near predicted monthly values during local day,
Enhanced by 20% during local night.
Southern Australian and New Zealand Region:
Enhanced by 15% during local day,
Enhanced by 20% during local night.
Enhanced by 25% after local dawn.
Antarctic Region (Casey/Scott Base):
Enhanced by 25% over the UT day.
Predicted Monthly T index for October: 54
4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
07 Oct 85 5 to 15% above predicted monthly values
08 Oct 70 5 to 10% above predicted monthly values
09 Oct 85 5 to 15% above predicted monthly values
COMMENT: Widespread and persistent spread-F conditions observed
over the UT day S. Aus/NZ/Antarctic regions. Expect normal to
enhanced ionospheric propagation conditions today at low to mid
latitudes. Possibile periods of degradation over the next two
days in association with increased geomagnetic activity, especially
at high latitudes.
