2A. MAGNETIC SUMMARY
Geomagnetic field for Australian Region 08 Jan: Quiet to unsettled
with active and minor storm periods at high latitudes.
Estimated Indices 08 Jan : A K

Darwin 7 22222222
Townsville 11 23332322
Learmonth 12 22333323

Observed Regional daily pc3 Indices 08 Jan :
Darwin 0 (Quiet)
Townsville 0 (Quiet)
Learmonth 0 (Quiet)
Canberra 0 (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 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
08 Jan 4
Observed Australian Regional MUFs
Equatorial PNG/Niue Region:
Near predicted monthly values with occasional
depressions to 25%. Some night spread F and sporadic E
observed at Vanimo.
Northern Australian Region:
Near predicted monthly values.
Southern Australian and New Zealand Region:
Near predicted monthly values. Sporadic E observed
observed mostly 00-08 and 20-23 UT. Sporadic E
observed 11-17 UT at Macquarie Island.
Antarctic Region (Casey/Scott Base/Davis/Mawson):
Near predicted monthly values to 30% depressed.
Predicted Monthly T index for January: 12
4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
09 Jan 5 Mostly near predicted monthly values. Depressions
to 20% possible at times.
10 Jan 5 Mostly near predicted monthly values. Depressions
to 20% possible at times.
11 Jan 5 Mostly near predicted monthly values. Depressions
to 20% possible at times.
COMMENT: Periods of sporadic E observed at all latitudes, sometimes
obscuring the F region. Expect summertime sporadic E to continue
to form. Longer distance HF sky wave communications may be affected
at times.
