SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 01/2330Z NOVEMBER 2002 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 01 NOVEMBER AND FORECAST FOR 02 NOVEMBER - 04 NOVEMBER
STATUS INDICATORS SOL:** YELLOW ** MAG:** YELLOW ** ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 01 Nov: Low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 01 Nov: 162/116
1B. SOLAR FORECAST
02 Nov 03 Nov 04 Nov
Activity Low to moderate Low to moderate Low to moderate
Fadeouts Possible Possible Possible
10.7cm/SSN 170/124 175/129 180/133
COMMENT: Solar region 162 has departed the solar disk. Still
maintaining watch on east limb around the solar equator for any
signs of an active region, after yesterdays simultaneous flare
in EIT with the X1 xray event. Solar proton flux levels are mildly
enhanced 1 proton flux unit at the 10MeV energy level. A isolated
equatorial coronal hole is now at the centre of the solar disk
(visible in SOHO EIT 284 imagey). Solar region 177 in the north-east
solar quadrant has shown rapid growth overnight.

Observed Regional daily pc3 Indices 01 NOV :
Townsville 31 (Quiet to unsettled)
Learmonth NA
Canberra 60 (Unsettled)
Hobart 28 (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 01 Nov : A
Fredericksburg 8
Planetary 12
Observed AFr/Ap Indices 31 Oct : A K
Fredericksburg 13
Planetary 18 4333 4433
2B. MAGNETIC FORECAST
Date Ap Conditions
02 Nov 12 Unsettled
03 Nov 16 Unsettled to active
04 Nov 25 Active to minor storm
COMMENT: IPS Geomagnetic Warning 38 was issued on 30 October
and is current for interval 3-4 November. Coronal hole induced
activity is expected 03-04 Nov.
-----------------------------------------------------------
3A. GLOBAL HF PROPAGATION SUMMARY
Latitude Band
Date Low Middle High
01 Nov Normal Normal-fair Normal-fair
PCA Event : No event. However flux levels mildly elevated.
3B. GLOBAL HF PROPAGATION FORECAST
Latitude Band
Date Low Middle High
02 Nov Normal Normal Normal-Fair
03 Nov Normal Normal-Fair Fair
04 Nov Fair Fair Fair-Poor
COMMENT: Degraded HF conditions expected 03-04 Nov at high latitudes.
Polar regions may experience increased absorption due to mild elevation
in proton flux levels.
-----------------------------------------------------------

Observed Australian Regional MUFs
Equatorial PNG Region:
Enhanced by 25-45% during local day,
Northern Australian Region:
Near predicted monthly values during local day,
Enhanced by 15% during local night.
Southern Australian and New Zealand Region:
Mostly near predicted monthly values,
Antarctic Region (Casey/Scott Base):
Enhanced by 15% over the UT day.
Predicted Monthly T index for November: 91
4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
02 Nov 130 about 15% above predicted monthly values
03 Nov 130 about 15% above predicted monthly values
04 Nov 100 near predicted monthly values/depressed 10 to
15%
COMMENT: Degradation expected southern Aus/NZ region 03-04 Nov.
