Mostly quiet to unsettled conditions. Active periods observed on 
20 and 21 April

2. FORECAST (24 APRIL - 24 MAY)
Disturbed Periods: 
No strong recurrent patterns, however mild activity may be experienced on:
 27 Apr,  2 May,  4 May,  8-9 May,  14 May,  16-18 May.

Best Quiet Periods: 
 24-26 Apr,  28 Apr to 1 May,  3 May,  5-7 May,  11-13 May,  15 May.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 24 Apr to 20 May.

Central Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 24 Apr to 16 May,  19-20 May.

Southern Australian Regions:
 Disturbed Periods: 17 May.
 Best Quiet Periods: 24 Apr to 15 May,  20 May.


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.
