SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 10/2330Z NOVEMBER 2002 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 10 NOVEMBER AND FORECAST FOR 11 NOVEMBER - 13 NOVEMBER
STATUS INDICATORS SOL:** YELLOW ** MAG:** RED ** ION: ** YELLOW **
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 10 Nov: Moderate
Flares Max Fadeout Freq. Sectors
M2/2N 0321UT possible lower E. Asia/Aust.
Observed 10.7 cm flux/Equivalent Sunspot Number for 10 Nov: 191/143
1B. SOLAR FORECAST
11 Nov 12 Nov 13 Nov
Activity Moderate Moderate Moderate
Fadeouts Possible Possible Possible
10.7cm/SSN 190/143 185/138 180/133
COMMENT: Regions 180 and 191 have the chance of producing further
M-class flare activity. The proton event which is currently in
progress is likely to finish early on 11 November.
-----------------------------------------------------------
2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 10 Nov: Quiet to Active
Estimated Indices 10 Nov : A K
Australian Region 15 4442 2223
Darwin - ---- ----
Townsville 15 4442 2222
Learmonth 16 5342 2223
Canberra 15 4442 2212
Hobart 15 4442 2212
Casey(Ant) 24 5-54 2224
Observed Regional daily pc3 Indices 10 NOV :
Townsville 2 (Quiet)
Learmonth NA
Canberra 36 (Quiet to unsettled)
Hobart 52 (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 10 Nov : A
Fredericksburg 12
Planetary 15
Observed AFr/Ap Indices 09 Nov : A K
Fredericksburg 3
Planetary 9 2212 2333
2B. MAGNETIC FORECAST
Date Ap Conditions
11 Nov 30 Initially quiet to unsettled with storm periods
expected later in the UT day.
12 Nov 30 Active to minor storm
13 Nov 20 Unsettled to active
COMMENT: The weak CME which impacted the Earth late in the UT
day of 9 November produced a minor storm period during 10 November.
The CME associated with the M4-flare observed on 9 November is
expected to impact the Earth during 11 November and produce minor
to major storm periods. Minor storm to active levels are expected
to continue into 12 November due to the continued CME effects
and the influence of an anticipated coronal hole.

3A. GLOBAL HF PROPAGATION SUMMARY
Latitude Band
Date Low Middle High
10 Nov Normal Normal Poor(PCA)-normal
PCA Event : 10Mev Proton/PCA Event Began 09 11 2002 1950UT and is in progress
3B. GLOBAL HF PROPAGATION FORECAST
Latitude Band
Date Low Middle High
11 Nov Normal-fair Normal-poor Poor
12 Nov Normal-fair Poor-fair Poor-fair
13 Nov Normal Normal-fair Fair
COMMENT: Increased absorption observed at Antarctic stations
due to PCA event in progress. PCA event is expected to finish
early on 11 November. HF conditions for low-mid latitudes are
expected to be initially enhanced for 11 November with possible
depressions of 15-30% later in the UT day of 11 November following
the impact of a CME. Depressions are expected to continue at
times for 12-13 November as geomagnetic activity continues.
-----------------------------------------------------------
4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY
Date T index
10 Nov 168
Observed Australian Regional MUFs
Equatorial PNG Region:
Near predicted monthly values to enhanced.
Australian and New Zealand Region:
Near predicted monthly values to enhanced.
Antarctic Region (Casey/Scott Base):
Proton event in progress, increased absorption observed.
Predicted Monthly T index for November: 91
4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
11 Nov 140 Initially enhanced with possible depressions
of 15-30% at times later in the UT day.
12 Nov 70 depressed 15 to 30%/near predicted monthly values
13 Nov 90 depressed 10 to 20%/near predicted monthly values
COMMENT: Increased absorption observed at Antarctic stations
due to PCA event in progress. PCA event is expected to finish
early on 11 November. HF conditions for low-mid latitudes are
expected to be initially enhanced for 11 November with possible
depressions of 15-30% later in the UT day of 11 November following
the impact of a CME. Depressions are expected to continue at
times for 12-13 November as geomagnetic activity continues.
