NOTE: Indices may have been generated from data obtained in 
cooperation with the following organisations: Geoscience Australia, 
University of Newcastle Space Physics Group, Australian Government 
Antarctic Division and International Center for Space Weather 
Science and Education, Japan.


Active to Minor Storm conditions 22-23 Jun due to CME activity. 
Quiet to unsettled on other days. Mostly Quiet to Unsettled conditions 
for the next 7 days. No significant coronal hole activity 
expected.

2. FORECAST (25 JUNE - 25 JULY)
Disturbed Periods: 5 Jul,  7 Jul,  11 Jul.

Best Quiet Periods:  29 Jun to 3 Jul,  6 Jul,  9 Jul,  
14-21 Jul.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 25 Jun to 21 Jul.

Central Australian Regions:
 Mildly Disturbed Periods: 05 Jul to 08 Jul, 11 Jul to 13 Jul
 Best Quiet Periods: 25 Jun to 4 Jul,  14-18 Jul,  21 Jul.

Southern Australian Regions:
 Disturbed Periods: 05 Jul to 08 Jul, 11 Jul to 13 Jul
 Best Quiet Periods: 25 Jun to 4 Jul,  09 Jul to 10 Jul,  14-18 Jul,  21 Jul.


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.
