                          Mar, a weak (22nT) impulse was observed 
                          at 0958UT.

*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.


Generally G0 conditions observed during the week, with a mild increase 
in geomagnetic activity (single G1 period) on 03-Mar due to a weak CME
arrival associated with a solar filament eruption on 28-Feb. The planetary 
conditions reached G1-G2 during the interval 03/12-21UT.

2. FORECAST (07 MARCH - 06 APRIL)
Disturbed Periods: 
9-10 Mar.

Best Quiet Periods: 
 12-22 Mar,  26-29 Mar,  31 Mar to 2 Apr.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 7-8 Mar, 11-Mar to 2-Apr.

Central Australian Regions: NA

Southern Australian Regions:
 Disturbed Periods: 09-10 Mar.
 Best Quiet Periods: 7-8 Mar, 11-Mar to 2-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.
