*estimated from real time 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.

Active on 29 Sep and short period of active levels on 03 Oct.
quiet to unsettled on other days.

2. FORECAST (04 OCTOBER - 03 NOVEMBER)
Disturbed Periods: 
active on 24-26 Oct.

Best Quiet Periods: 
 5 Oct to 16 Oct,  22 Oct to 23 Oct.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions: NA

Central Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 6 Oct to 17 Oct,  21 Oct to 23 Oct,  27 Oct to 30 Oct.

Southern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 4 Oct to 17 Oct,  22 Oct to 23 Oct,  28 Oct to 30 Oct.

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.
