 Best Quiet Periods: 13 Feb to 11 Mar.

Central Australian Regions:
 Disturbed Periods: Mildly disturbed 15-Feb.
 Best Quiet Periods: 13-14 Feb, 16 Feb to 11 Mar.

Southern Australian Regions:

 Best Quiet Periods: 13-14 Feb, 16 Feb to 6 Mar,  9-11 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.
