Observed Regional daily pc3 Indices 23 Jul : 
      Canberra             0   (Quiet)
      Learmonth            0   (Quiet)
      Culgoora             4   (Quiet)
      Hobart               0   (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.

2B. MAGNETIC FORECAST 
Date      Ap    Conditions
24 Jul    20    Unsettled to active with the slight chance of 
                minor storm periods. 
25 Jul    15    Unsettled to active 
26 Jul     8    Quiet to Unsettled 
COMMENT: IPS Geomagnetic Warning 8 was issued on 21 July and 
is current for interval 24-25 July. The CME observed on 20 July 
may have a glancing impact on the Earth during 24-25 July and 
produce mildly elevated geomagnetic activity levels during this 
period.

COMMENT: HF conditions are expected to be slightly degraded for 
high-mid latitudes for 24-25 July as the result of anticipated 
mildly elevated geomagnetic activity levels. Slightly degraded 
conditions are also possible for equatorial latitudes during 
local day.

4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY


Date   T index
23 Jul    26

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

Predicted Monthly T index for July:  13

4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date   T index  MUFs
24 Jul    10    near predicted monthly values/depressed 5 to 
                10% 
25 Jul    10    depressed 5 to 10%/near predicted monthly values 
26 Jul    15    Near predicted monthly values 
COMMENT: HF conditions are expected to be slightly degraded for 
southern Aus/NZ regions for 24-25 July as the result of anticipated 
mildly elevated geomagnetic activity levels. Slightly degraded 
conditions are also possible for northern Australian regions 
during local day.
