10.7cm/SSN 66/0 66/0 66/0
COMMENT: Very low solar activity over the last 24 hours. Solar
activity is expected to remain at very low levels for the next
3 days. Solar disk is spotless. Solar wind remains around normal
levels 400 km/s. The Bz component of the interplanetary magnetic
field ranged between +/- 5nT.

Observed Regional daily pc3 Indices 30 Jul :
Darwin 0 (Quiet)
Townsville 0 (Quiet)
Learmonth 0 (Quiet)
Alice_Springs 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
30 Jul 12
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 during local day,
Enhanced by 10% during local night.
Antarctic Region (Casey/Scott Base/Davis/Mawson):
Enhanced by 10% over the UT day.
Predicted Monthly T index for July: 4
4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date T index MUFs
31 Jul 5 near predicted monthly values
01 Aug 5 near predicted monthly values
02 Aug 5 near predicted monthly values
COMMENT: Mostly normal HF conditions observed over the last 24
hours. Noted sporadic E around the sunset times in Vanimo and
Darwin. Expect normal conditions in the Northern AUS/Equatorial
regions. Also expect Normal conditions for Southern AUS/NZ regions
with continued slight enhancements during local night. Slightly
enhanced conditons are expected in the antarctic region, however,
periods without a trace were noted on some ionograms.
