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

2. FORECAST (17 MARCH - 16 APRIL)
Disturbed Periods: 
2-3 Apr, 7 Apr,  11-13 Apr.

Best Quiet Periods: 
 19-27 Mar,  29 Mar to 1 Apr, 9 Apr, 15-16 Apr.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: 
 Quiet

Central Australian Regions: 
 Quiet 18 Mar-2 Apr, 4-7 Apr, 9-10 Apr, 14-16 Apr
 Mildly disturbed 17 Mar, 3 Apr, 8 Apr, 11-13 Apr

Southern Australian Regions: NA
 Quiet 18 Mar-2 Apr, 4-7 Apr, 9-10 Apr, 14-16 Ap
 Disturbed 17 Mar, 3 Apr, 8 Apr, 11-13 Apr
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.
