Solar wind speed remains at normal levels and is steady at around 
340 km/s. Solar activity is expected to be very low for the next 
few days.

2A. MAGNETIC SUMMARY

Geomagnetic field for Australian Region 05 Feb: Quiet

Observed Regional daily pc3 Indices 05 Feb : 
      Darwin               0   (Quiet)
      Townsville           0   (Quiet)
      Learmonth            7   (Quiet)
      Camden               4   (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.

COMMENT: Maximum usable frequencies were very close to normal 
throughout the UT day at all latitudes. Persistent cases of sporadic 
E were observed at all latitudes throughout the UT day however, 
causing partial or complete blanketing of the highest ionospheric 
layers. Sporadic E was particularly strong at low and low to 
mid latitudes. Simalar HF conditions are likely to be repeated 
over the next 24 hours.

4A. AUSTRALIAN REGION IONOSPHERIC SUMMARY


Date   T index
05 Feb     6

Observed Australian Regional MUFs
near predicted monthly values

Predicted Monthly T index for February:  11

4B. AUSTRALIAN REGION IONOSPHERIC FORECAST
Date   T index  MUFs
06 Feb    12    Near predicted monthly values 
07 Feb    11    Near predicted monthly values 
08 Feb    11    Near predicted monthly values 
COMMENT: Ionospheric support was very close to normal throughout 
the UT day across all Australasian regions. Persistent cases 
of sporadic E were observed throughout the UT day in all regions 
however, causing partial or complete blanketing of the highest 
ionospheric layers. Sporadic E was particularly strong in
Equatorial/Pacific and Northern Australian regions. Simalar 
ionospheric conditions are expected over the next 24 hours.
