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.

G0 geomagnetic activity was observed this week, though mildly elevated
activity was observed on 01-Feb. 

2. FORECAST (06 FEBRUARY - 08 MARCH)
Disturbed Periods: 
 28 Feb to 01 Mar.

Best Quiet Periods: 
 6-8 Feb,  10 Feb,  14 Feb,  17-18 Feb,  20-23 Feb,  25-27 Feb,  2-4 Mar.

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

Central Australian Regions:
 Mildly Disturbed Periods: 28-Feb to 01-Mar, 16-17 Feb.
 Best Quiet Periods: 6-14 Feb, 19-26 Feb, 3-8 Mar.

Southern Australian Regions: 
 Disturbed Periods: 28-Feb to 01-Mar, 16-17 Feb.
 Best Quiet Periods: 6-14 Feb, 19-26 Feb, 3-8 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.
