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 on 8-9 Dec.   Quiet to unsettled on other days.

2. FORECAST (15 DECEMBER - 14 JANUARY)
Disturbed Periods: 
21-22 Dec,  4-5 Jan.

Best Quiet Periods: 
 15 Dec,  17-18 Dec,  25 Dec to 2 Jan,  8-10 Jan.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: NA

Central Australian Regions: NA

Southern Australian Regions:
 Disturbed Periods: 20-23 Dec,  3-7 Jan.
 Best Quiet Periods: 15 Dec,  17-18 Dec,  25 Dec to 2 Jan,  8-10 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.
