cooperation with the following organisations: Geoscience Australia, 
University of Newcastle Space Physics Group, Australian Government 
Antarctic Division and Space Environment Research Center, Japan.


Quiet to unsettled conditions.

2. FORECAST (19 JANUARY - 18 FEBRUARY)
Disturbed Periods: 
No strong recurrent patterns, however minor to mild activity may 
be experienced on:
  19 Jan, 20 Jan, 22 Jan, 30 Jan and 12 Feb.

Best Quiet Periods: 
 21 Jan, 23 to 29 Jan,  31 Jan to 11 Feb,  13 Feb to 18 Feb.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions: NA

Central Australian Regions: NA

Southern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 19 Jan to 14 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.
