active on 4 Feb.
quiet to unsettled on other days.

2. FORECAST (10 FEBRUARY - 12 MARCH)
Disturbed Periods: 
No strong recurrent patterns, however mild activity may be experienced on:

Best Quiet Periods: 
  14 Feb to 27 Feb,  1 Mar to 2 Mar,   6 Mar to 8 Mar.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions: NA

Central Australian Regions:
 Mildly Disturbed Periods: 4-5 March
 Best Quiet Periods: 10 Feb to 19 Feb.

Southern Australian Regions:
 Disturbed Periods: 4-5 March

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.
