*estimated from real time data

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.

Active conditions on 24Feb, 01Mar-02Mar due to coronal hole effects.  
Quiet to Unsettled conditions expected for the next 7 days with only
minor coronal hole effects possible 7Mar.

2. FORECAST (05 MARCH - 04 APRIL)
Disturbed Periods: 28-29 Mar.

Best Quiet Periods:  8-15 Mar,  18-21 Mar,  24-26 Mar.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: Quiet

Central Australian Regions:
 Mild Disturbed Periods: 28-29 Mar, possible 7Mar. 
 Best Quiet Periods: 5-23 Mar,  25-26 Mar,  30-31 Mar.

Southern Australian Regions:
 Disturbed Periods: 28-29 Mar, possible 7Mar.
 Best Quiet Periods: 5-22 Mar,  25-26 Mar,  30 Mar.


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.
