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 (10 JANUARY - 09 FEBRUARY)
Disturbed Periods: 
No strong recurrent patterns, however mild activity may be experienced on:
 13 Jan,  16 Jan.

Best Quiet Periods: 
 10-12 Jan,  14-15 Jan,  17 Jan to 5 Feb.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: None expected

Central Australian Regions: None expected

Southern Australian Regions: None expected


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.
