Antarctic Division and International Center for Space Weather 
Science and Education, Japan.


Quiet to unsettled conditions.

2. FORECAST (25 JANUARY - 24 FEBRUARY)
Disturbed Periods:
Very few clear recurrence patterns currently exist, most geomagnetic
activity has been caused by CMEs recently.  
25-27 Jan, 30-Jan, 6-Feb.

Best Quiet Periods: 
1-4 Feb, 7-24 Feb.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 29-Jan to 24-Feb.

Central Australian Regions: 
 Disturbed Periods: None
 Best Quiet Periods: 29-Jan to 24-Feb

Southern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 30-Jan to 5-Feb, 10-24 Feb


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.
