SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 08/2330Z JANUARY 2003 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 08 JANUARY AND FORECAST FOR 09 JANUARY - 11 JANUARY
STATUS INDICATORS SOL:** YELLOW ** MAG:GREEN ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 08 Jan: Moderate
Flares Max Fadeout Freq. Sectors
M4/0F 07/2333UT possible lower West Pacific
Observed 10.7 cm flux/Equivalent Sunspot Number for 08 Jan: 174/128
1B. SOLAR FORECAST
09 Jan 10 Jan 11 Jan
Activity Low to moderate Low to moderate Low to moderate
Fadeouts Possible Possible Possible
10.7cm/SSN 180/133 185/138 190/143
COMMENT: Solar region 251, located near the east limb, produced
an M4.9 level flare at 07/2330. Several other C-class events
occurred throughout the UT day, mainly from regions 244 and 242.
A trans-equatorial north-polar coronal hole is in geoeffective
longitude, and weak coronal hole wind stream effects may be
experienced in the next few days.

2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 08 Jan: Quiet
Estimated Indices 08 Jan : A K
Australian Region 4 2121 1113
Darwin 5 2221 1123
Townsville 4 2121 1113
Learmonth 3 2111 1112
Canberra 3 2121 0113
Hobart 4 2221 1102
Casey(Ant) 9 4--2 2112
Observed Regional daily pc3 Indices 08 JAN :
Townsville 0 (Quiet)
Learmonth NA
Canberra 0 (Quiet)
Hobart 7 (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 08 Jan : A
Fredericksburg 6
Planetary 9
Observed AFr/Ap Indices 07 Jan : A K
Fredericksburg 5
Planetary 9 2323 2232
2B. MAGNETIC FORECAST
Date Ap Conditions
09 Jan 10 Quiet to Unsettled
10 Jan 15 Unsettled to Active
11 Jan 12 Unsettled
COMMENT: A trans-equatorial north-polar coronal hole is now in
geoeffective longitude, and mild geomagnetic disturbance due
to a weak coronal hole wind stream may be experienced over the
next few days.

08 Jan Normal Normal Normal
PCA Event : No event.
3B. GLOBAL HF PROPAGATION FORECAST
Latitude Band
Date Low Middle High
09 Jan Normal Normal Normal-Fair
10 Jan Normal Normal Normal-Fair
11 Jan Normal Normal Normal-Fair
COMMENT: Mildly degraded conditions expected 9-10 Jan at high
latitudes. Otherwise generally good HF conditions expected.
-----------------------------------------------------------
4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY
Date T index
08 Jan 129
Observed Australian Regional MUFs
Equatorial PNG Region:
Near predicted monthly values.
Northern Australian Region:
Enhanced by 15% during local day,
Near predicted monthly values during local night.
Southern Australian and New Zealand Region:
Near predicted monthly values during local day,
Enhanced by 20% during local night.
Antarctic Region (Casey/Scott Base):
Near predicted monthly values over the UT day.
Predicted Monthly T index for January: 89
4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
09 Jan 130 about 10% above predicted monthly values
10 Jan 120 about 10% above predicted monthly values
11 Jan 130 about 10% above predicted monthly values
COMMENT: Good HF conditions expected today. Mild degradation
possible tomorrow at high latitudes due to anticipated weak coronal
hole wind stream effects.
