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.


Quiet to Unsettled conditions expected for the next 7 days with 
possible Active periods on 27Jan-29Jan due to coronal hole effects.

2. FORECAST (26 JANUARY - 25 FEBRUARY)
Disturbed Periods: 
 1-2 Feb,  14 Feb.

Best Quiet Periods: 
  7-13 Feb,  16 Feb,  19-21 Feb.

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

Central Australian Regions:
 Mildly Disturbed: 27-29Jan, 1-6 Feb

Southern Australian Regions:
 Disturbed Periods: 27-29Jan, 1-6 Feb
 Best Quiet Periods:  6-10 Feb,  12-14 Feb,  16 Feb,  18 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.
