Observed Regional daily pc3 Indices 23 Jan :
Darwin 0 (Quiet)
Townsville 0 (Quiet)
Learmonth 0 (Quiet)

Camden 0 (Quiet)
Gnangara 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
23 Jan -18
Observed Australian Regional MUFs
Equatorial PNG/Niue Region:
Near predicted monthly values during local day,
Depressed by 20% during local night.
Northern Australian Region:
Near predicted monthly values during local day,
Depressed by 15% during local night.
Southern Australian and New Zealand Region:
Depressed by 15% during local day,
Depressed 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 January: 6
4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
24 Jan -15 near predicted monthly values/depressed 10 to
20%
25 Jan -15 near predicted monthly values/depressed 10 to
20%
26 Jan -15 near predicted monthly values/depressed 10 to
20%
COMMENT: Intermittent sporadic-E events again observed throughout
the region. MUFs were mildly depressed in all regions, particularly
overnight. There were some significant local depressions during
the day in the equatorial region. Continuing Sporadic-E events
likely from Equatorial to S.Aus/NZ regions. Expect continuing
variable HF conditions with mild MUF depressions 24 Jan.
