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 Space Environment Research Center, Japan.


Active on 1 Mar,  7 Mar. Quiet to unsettled on other days.

2. FORECAST (08 MARCH - 07 APRIL)
Disturbed Periods: 
 08-09 Mar.

Best Quiet Periods: 
 14-16 Mar,  19 Mar,  21-24 Mar,  27 Mar,  3 Apr.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: 
 Disturbed Periods: 08-09 Mar.

Central Australian Regions:
 Disturbed Periods: 08-09 Mar.
 Best Quiet Periods: 14-17 Mar,  20 Mar,  2-3 Apr.

Southern Australian Regions:
 Disturbed Periods: 08-10 Mar.
 Best Quiet Periods: 14-17 Mar,  20 Mar,  2-3 Apr.


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.
