SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 02/2330Z OCTOBER 2006 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 02 OCTOBER AND FORECAST FOR 03 OCTOBER - 05 OCTOBER
STATUS INDICATORS SOL:GREEN MAG:GREEN ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 02 Oct: Very low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 02 Oct: 78/17
1B. SOLAR FORECAST
03 Oct 04 Oct 05 Oct
Activity Very low Very low Very low
Fadeouts None expected None expected None expected
10.7cm/SSN 80/20 80/20 80/20
COMMENT: The solar wind has slowly decreased over the last 24
hours and is currently 450 km/s. Expect continued steady decrease
in wind speed as coronal hole regions move away from a geo-effective
position. The Bz component of the interplanetary magnetic field
(IMF) is mainly neutral at +/- 2 nT.
-----------------------------------------------------------
2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 02 Oct: Quiet
Estimated Indices 02 Oct : A K
Australian Region 6 12222221
Darwin 6 22222121
Learmonth 6 12212222
Culgoora 5 11222221
Camden 6 12222221
Canberra 6 12222221
Hobart 6 12222221
Casey(Ant) 10 23422222
Observed Regional daily pc3 Indices 02 Oct :
Charters_Towers 0 (Quiet)
Learmonth 2 (Quiet)
Camden 8 (Quiet)
Hobart 40 (Quiet to unsettled)
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 02 Oct : A
Fredericksburg 8
Planetary 8
Observed AFr/Ap Indices 01 Oct : A K
Fredericksburg 14
Planetary 25 5544 3313
2B. MAGNETIC FORECAST
Date Ap Conditions
03 Oct 8 Quiet to Unsettled
04 Oct 6 Quiet
05 Oct 5 Quiet
COMMENT: Expect the geomagnetic field to return to quiet conditions
as the effects of the high speed wind stream dissipate.
-----------------------------------------------------------
3A. GLOBAL HF PROPAGATION SUMMARY
Latitude Band
Date Low Middle High
02 Oct Fair-normal Normal Normal
PCA Event : No event.
3B. GLOBAL HF PROPAGATION FORECAST
Latitude Band
Date Low Middle High
03 Oct Normal Normal Normal-Fair
04 Oct Normal Normal Normal
05 Oct Normal Normal Normal
COMMENT: HF conditions throughout the Australasian region have
returned to normal as effects from the disturbed geomagnetic
field dissipate.
-----------------------------------------------------------
4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY
Date T index
02 Oct -2
Observed Australian Regional MUFs
near predicted monthly values
Predicted Monthly T index for October: 11
4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
03 Oct 5 near predicted monthly values
04 Oct 11 near predicted monthly values
05 Oct 11 near predicted monthly values
COMMENT: Expect normal HF conditions in all Australasian regions
as the effects of recent geomagnetic disturbances dissipate.
-----------------------------------------------------------
