SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 09/2330Z NOVEMBER 2002 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 09 NOVEMBER AND FORECAST FOR 10 NOVEMBER - 12 NOVEMBER
STATUS INDICATORS SOL:* YELLOW * MAG:* YELLOW * ION: * YELLOW *
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 09 Nov: Moderate
Flares Max Fadeout Freq. Sectors
M4/2B 1323UT possible lower European
Observed 10.7 cm flux/Equivalent Sunspot Number for 09 Nov: 191/143
1B. SOLAR FORECAST
10 Nov 11 Nov 12 Nov
Activity Low to moderate Low to moderate Low to moderate
Fadeouts Possible Possible Possible
10.7cm/SSN 185/138 180/133 180/133
COMMENT: Region 180 produced an M-class flare and several C class
flares. The M4 level flare had a reported type II/IV radio sweep
associated and produced a semi halo CME in the western solar
hemisphere, which will possibly be geoeffective on or around
Nov 12. Region 191 produced an impulsive flare of high C-class
intensity.
A possible weak shock was observed in the solar wind at 1755UT
on 09 Nov.

2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 09 Nov: Quiet to Unsettled
Estimated Indices 09 Nov : A K
Australian Region 4 2121 0123
Darwin - ---- ----
Townsville 5 2121 0133
Learmonth 5 1021 0235
Canberra 3 1021 0123
Hobart 3 1021 0123
Casey(Ant) 10 3333 1123
Observed Regional daily pc3 Indices 09 NOV :
Townsville 0 (Quiet)
Learmonth 0 (Quiet)
Canberra 13 (Quiet)
Hobart 8 (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.
Estimated AFr/Ap Indices 09 Nov : A
Fredericksburg 8
Planetary 12
Observed AFr/Ap Indices 08 Nov : A K
Fredericksburg 3
Planetary 8 2222 3232
2B. MAGNETIC FORECAST
Date Ap Conditions
10 Nov 12 Unsettled
11 Nov 20 active
12 Nov 20 active
COMMENT: A moderate step increase in solar wind speed, and slightly
elevated geomagnetic activity were observed after 18UT. Increased
magnetic disturbance is expected over the next few days as a
northern solar hemisphere coronal hole rotates into geoeffective
location. There is also a possibility of disturbance due to recent
flare activity.
-----------------------------------------------------------
3A. GLOBAL HF PROPAGATION SUMMARY
Latitude Band
Date Low Middle High
09 Nov Normal Normal Normal-fair
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
10 Nov Normal Normal Poor(PCA)
11 Nov Normal Normal-Fair Fair
12 Nov Normal Normal-Fair Fair
COMMENT: Increased absorption observed at Antarctic stations
due to PCA event in progress. Expect similar conditions to continue
today.
-----------------------------------------------------------
4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY
Date T index
09 Nov 170
Observed Australian Regional MUFs
10 to 20% above predicted monthly values
Predicted Monthly T index for November: 91
4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
10 Nov 150 Near predicted monthly values to enhanced by
15% for Northern regions with possible depressions
of 15% at times for Southern regions.
11 Nov 140 Near predicted monthly values to enhanced by
15% for Northern regions with possible depressions
of 15% at times for Southern regions.
12 Nov 120 Near predicted monthly values to enhanced by
15% for Northern regions with possible depressions
of 15% at times for Southern regions.
COMMENT: Ionospheric conditions are generally good but coronal
hole and solar flare induced disturbance is possible over the
next few days.
