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.


Quiet to unsettled conditions.

2. FORECAST (29 DECEMBER - 28 JANUARY)
Disturbed Periods: 
30-31 Dec,  4-7 Jan,  17-23 Jan.

Best Quiet Periods: 
 1-3 Dec,  8-16 Jan, 24 -28 Jan.

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

Central Australian Regions: 
Moderately disturbed: 4-9 Jan, 17-23 Jan

Southern Australian Regions: NA
Disturbed: 4-9 Jan, 17-23 Jan

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.
