SUBJ: IPS DAILY SOLAR AND GEOPHYSICAL REPORT
ISSUED AT 04/2330Z NOVEMBER 2002 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 04 NOVEMBER AND FORECAST FOR 05 NOVEMBER - 07 NOVEMBER
STATUS INDICATORS SOL:** YELLOW ** MAG:** YELLOW ** ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 04 Nov: Low
Flares: none.
Observed 10.7 cm flux/Equivalent Sunspot Number for 04 Nov: 177/131
1B. SOLAR FORECAST
05 Nov 06 Nov 07 Nov
Activity Moderate Moderate Moderate
Fadeouts Probable Probable Probable
10.7cm/SSN 175/129 175/129 180/133
COMMENT: The interplanetary magnetic field was again mildly southward
(-5nT) for most of the UT day. Solar wind speed continues to
be moderately elevated at 520km/sec, in association with an equatorial
coronal hole, now in the western solar hemisphere. Solar regions
177 and 180 appear to have M class flare potential, and activity
on the Culgoora spectrograph appears to have increased this morning.

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.

4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY
Date T index
04 Nov 100
Observed Australian Regional MUFs
Equatorial PNG Region:
Enhanced by 15% during local day,
Enhanced by 45% during local night.
Northern Australian Region:
Mostly near predicted monthly values,
Southern Australian and New Zealand Region:
Depressed by 20-30% during local day,
Near predicted monthly values during local night.
Antarctic Region (Casey/Scott Base):
Depressed 15% to near predicted monthly values.
Spread F and absorption observed.
Predicted Monthly T index for November: 91
4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
05 Nov 110 depressed 10 to 15%/near predicted monthly values
06 Nov 130 about 10% above predicted monthly values
07 Nov 130 about 10% above predicted monthly values
COMMENT: Depressed MUFs observed yesterday in southern Aus/NZ
region. A mildler depression in MUF levels for southern region
is again expected early today, then improving. There is an increasing
chance for fadeouts.
