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

region. A mildler depression in MUF levels for southern region 
is again expected early today, then improving. There is an increasing 
chance for fadeouts.
