Antarctic Division and Space Environment Research Center, Japan.


Quiet to Unsettled conditions.  

2. FORECAST (12 JUNE - 12 JULY)
Disturbed Periods: 
Active on 16 Jun to 17 Jun.

Best Quiet Periods: 
 12 Jun to 14 Jun,  20 Jun to 23 Jun,  29 Jun to 2 Jul,  5 Jul to 8 Jul.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions: NA

Central Australian Regions:
 Disturbed Periods:  15 Jun.
 Best Quiet Periods:  12 Jun,  18 Jun to 21 Jun,   24 Jun.

Southern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 18 Jun to 24 Jun.

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.
