Active on 3-4 Feb.   Quiet to unsettled on other days.

2. FORECAST (10 FEBRUARY - 12 MARCH)
Disturbed Periods: 
10-14 Feb,  24-25 Feb,  2-5 Mar,  11-12 Mar.

 16-22 Feb,  26 Feb to 1 Mar,  7-9 Mar.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 10 Feb to 12 Mar.

Central Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 6 Feb to 1 Mar,  6-9 Mar.

Southern Australian Regions:
 Disturbed Periods: 12-14 Feb,  3-5 Mar.  11-12 Mar.
 Best Quiet Periods: 16 Feb to 1 Mar,  6-9 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.
