1A. SOLAR SUMMARY
Activity 13 Oct:  Very low

Flares: none.

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


1B. SOLAR FORECAST
             14 Oct             15 Oct             16 Oct
Activity     Very low           Very low           Very low
Fadeouts     None expected      None expected      None expected
10.7cm/SSN    69/3               69/3               69/3
COMMENT: There are no visible sunspots on the solar disk. The 
density of the solar wind was at elevated levels throughout the 
UT day. Solar wind speed remains at low levels and is expected 
to remain at low levels over the next 3 days.

2A. MAGNETIC SUMMARY

Geomagnetic field for Australian Region 13 Oct: Quiet

Observed Regional daily pc3 Indices 13 Oct : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            0   (Quiet)
      Camden               2   (Quiet)
      Canberra             0   (Quiet)
      Hobart               4   (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 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 Oct     4

Observed Australian Regional MUFs
   Equatorial PNG/Niue Region:
      Near predicted monthly values during local day,
      Depressed by 35% during local night.
   Northern Australian Region:
      Depressed by 15% during local day,
      Near predicted monthly values during local night.
      Depressed by 20% after local dawn.
   Southern Australian and New Zealand Region:
      Near predicted monthly values during local day,
      Enhanced by 15% during local night.
   Antarctic Region (Casey/Scott Base/Davis/Mawson):
      Near predicted monthly values over the UT day.

Predicted Monthly T index for October:  10

4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date   T index  MUFs
14 Oct     0    near predicted monthly values 
15 Oct     0    near predicted monthly values 
16 Oct     0    near predicted monthly values 
COMMENT: Ionospheric support continues to be weak in equatorial 
PNG/Pacific regions, particular during night time hours, due 
to very low levels of solar ionising radiation.
