SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 08/2330Z NOVEMBER 2002 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 08 NOVEMBER AND FORECAST FOR 09 NOVEMBER - 11 NOVEMBER
STATUS INDICATORS SOL:* YELLOW * MAG:* YELLOW * ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 08 Nov: Low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 08 Nov: 189/142
1B. SOLAR FORECAST
09 Nov 10 Nov 11 Nov
Activity Low to moderate Low to moderate Low to moderate
Fadeouts Possible Possible Possible
10.7cm/SSN 190/143 185/138 185/138
COMMENT: Solar activity remained low. A long duration C7 flare
produced a mass ejection which appeared mainly south-west directed.
An earlier impulsive flare produced a north-west directed CME.
Neither CME appears earth-directed. The probable source is region
180, which remains magnetically complex.
-----------------------------------------------------------
2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 08 Nov: Quiet to Unsettled
Estimated Indices 08 Nov : A K
Australian Region 7 2223 2112
Darwin - ---- ----
Townsville 6 2113 202-
Learmonth 5 2222 1111
Canberra 6 2213 2012
Hobart 4 2112 1111
Casey(Ant) 10 3-33 2122
Observed Regional daily pc3 Indices 08 NOV :
Townsville 8 (Quiet)
Learmonth 0 (Quiet)
Canberra 70 (Active)
Hobart 78 (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 08 Nov : A
Fredericksburg 8
Planetary 8
Observed AFr/Ap Indices 07 Nov : A K
Fredericksburg 10
Planetary 14 4333 3333
2B. MAGNETIC FORECAST
Date Ap Conditions
09 Nov 8 Quiet to Unsettled
10 Nov 12 Unsettled
11 Nov 20 active
COMMENT: Solar wind parmeters indicate that present coronal hole
effects are declining. There is the small chance of a glancing
blow from weak CME activity observed during 7 November on 10
November that may produce a slight increase in geomagnetic activity.
Further coronal hole activity is expected to commence on 11 November.
-----------------------------------------------------------
3A. GLOBAL HF PROPAGATION SUMMARY
Latitude Band
Date Low Middle High
08 Nov Normal Normal Normal
PCA Event : No event.
3B. GLOBAL HF PROPAGATION FORECAST
Latitude Band
Date Low Middle High
09 Nov Normal Normal Normal-Fair
10 Nov Normal Normal Normal-Fair
11 Nov Normal Normal-Fair Fair
-----------------------------------------------------------
4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY
Date T index
08 Nov 156
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
09 Nov 150 10 to 15% above predicted monthly values
10 Nov 150 10 to 15% above predicted monthly values
11 Nov 140 10 to 15% above predicted monthly values
COMMENT: HF conditions should be mostly good for the next few
days. Higher HF frequencies may be affected by coronal hole induced
disturbance expected to commence around Nov 11.
