Antarctic Division and International Center for Space Weather 
Science and Education, Japan.

G0 conditions observed all week.

2. FORECAST (22 FEBRUARY - 23 MARCH)
Disturbed Periods: 
Late 24 and first half of 25-Feb. Possible CME component arrival.

Best Quiet Periods: 
 22-23 Feb,  27 to 8 Mar,  10-19 Mar.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 22 to 23 Feb, 26 Feb to 19 Mar.

Central Australian Regions: NA

Southern Australian Regions:
 Disturbed Periods: 09-Mar, 25-Feb
 Best Quiet Periods: 22 Feb to 23 Feb, 27 Feb to 7 Mar,  12-19 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.
