*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.


Quiet to unsettled conditions.

2. FORECAST (13 DECEMBER - 12 JANUARY)
Disturbed Periods: 
active 17 Dec to 19 Dec.

Best Quiet Periods: 
 14 Dec to 16 Dec,  24 Dec to 5 Jan.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions: NA

Central Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods:  13 Dec,  20 Dec to 28 Dec.

Southern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods:  13 Dec,  21 Dec to 28 Dec.

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.
