FROM THE AUSTRALIAN SPACE FORECAST CENTRE
SUMMARY FOR 13 AUGUST AND FORECAST FOR 14 AUGUST - 16 AUGUST
STATUS INDICATORS SOL:GREEN   MAG:GREEN     ION: GREEN
-----------------------------------------------------------
1A. SOLAR SUMMARY
Activity 13 Aug:  Very low

Flares: none.

Observed 10.7 cm flux/Equivalent Sunspot Number for 13 Aug:  68/2

1B. SOLAR FORECAST
             14 Aug             15 Aug             16 Aug
Activity     Very low           Very low           Very low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN    70/5               70/5               65/0

COMMENT: The solar wind is presently at around 350km/s and is 
expected to remain at this level till early 16 August when it 
is expected to go trough a Solar Sector Boundry and gradually 
increase to approximately 500km/s. The Bz component of the
interplanetary magnetic field has fluctuated between +/-2nT 
over the last 24 hours.

Observed Regional daily pc3 Indices 13 Aug : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            0   (Quiet)
      Camden              NA
      Canberra             0   (Quiet)
      Hobart              33   (Quiet to unsettled)
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 and have been shown to be
well correlated with rejection of high resolution aeromagnetic
survey flight-line data. 

NOTE: Indices may have been generated from data obtained in 
cooperation with the following organisations: Geoscience Australia, 
University of Newcastle Space Physics Group, Australian Government 
Antarctic Division and Space Environment Research Center, Japan.

4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY

Date   T index
13 Aug     9

Observed Australian Regional MUFs
   Equatorial PNG/Niue Region:
      Near predicted monthly values.
   Northern Australian Region:
      Near predicted monthly values.
   Southern Australian and New Zealand Region:
      Near predicted monthly values.
   Antarctic Region (Casey/Scott Base/Davis/Mawson):
      Near predicted monthly values over the UT day.
      Ionograms show no night time trace for most
      of the antarctic region, when a trace is shown
      it is near predicted monthly values.

Predicted Monthly T index for August:   9

Date   T index  MUFs
14 Aug     9    near predicted monthly values 
15 Aug     9    Near predicted monthly values
