Disturbed Periods: 
2-3 Apr,  7-8 Apr, 11-13 Apr.

Best Quiet Periods: 
 4-6 Apr,  9 Apr,  18 Apr,  20-22 Apr,  26 Apr.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Southern Australian Regions: Disturbed 2-3 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.
