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 (04 DECEMBER - 03 JANUARY)
Disturbed Periods: 
No strong recurrent patterns, however mild activity may be experienced on:
 4 Dec to 6 Dec,   13 Dec,  22 Dec to 23 Dec.

Best Quiet Periods: 
 7 Dec to 12 Dec,  14 Dec to 21 Dec,  24 Dec to 30 Dec.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions: NA

Central Australian Regions: NA

Southern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 4 Dec to 26 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.

PLEASE NOTE:
Geomagnetic activity can frequently be determined by short timescale 
solar events that cannot be forecast a week in advance, particularly
at solar maximum.
