Active on 11 Feb.   Quiet to unsettled on other days.

2. FORECAST (15 FEBRUARY - 16 MARCH)
Disturbed Periods: 
No strong recurrent patterns, however mild activity may be experienced on:
  15-16 Feb,  18 Feb, 24-25 Feb

Best Quiet Periods: 
17-Feb, 19-23 Feb, 26-Feb to 02-Mar, 05-08 Mar.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: 
Disturbed and mildly disturbed periods: None.
Best quiet periods: 15-Feb to 16-Mar.

Central Australian Regions: 
Disturbed periods: none.
Mildly disturbed periods: none.
Best quiet periods: 17-Feb, 19-23 Feb, 26-Feb to 02-Mar, 05-08 Mar. 

Southern Australian Regions:
 Disturbed Periods: none.
 Best Quiet Periods: 19-23 Feb, 27-Feb to 01-Mar, 05-Feb to 08-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.
