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 International Center for Space Weather 
Science and Education, Japan.


Active with isolated minor storm periods on 5 Dec. Quiet to active on 6 Dec. 
Quiet to unsettled on other days.

2. FORECAST (07 DECEMBER - 06 JANUARY)
Disturbed Periods: 
18 Dec,  1-2 Jan.

Best Quiet Periods: 
 8-10 Dec,  14-17 Dec,  22-26 Dec,  28-30 Dec.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: 
	All days quiet. No disturbed period.

Central Australian Regions: 
	Quiet periods: 7 Dec, 9-17 Dec, 20-31 Dec, 3 Jan
	Mildly disturbed periods: 8 Dec, 18-19 Dec

Southern Australian Regions: 
	Quiet periods: 7 Dec, 9-17 Dec, 20-31 Dec, 3 Jan
	Disturbed periods: 8 Dec, 18-19 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.
