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.

G1 geomagnetic conditions were observed on 28-Jun due to a CME arrival.
G0 geomagnetic conditions were observed on all other days. 

2. FORECAST (04 JULY - 03 AUGUST)
Disturbed Periods: 
No strong recurrent patterns, however mild activity may be experienced on:
 7-8 Jul,  12-17 Jul, 22-27 Jul.

Best Quiet Periods: 
 5-6 Jul,  9-11 Jul,  18-19 Jul,  21 Jul,  28-30 Jul.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 4-Jul to 03-Aug.

Central Australian Regions:
 Mildly Disturbed Periods: 15-16 Jul.
 Best Quiet Periods: 4-13 Jul, 18-Jul to 03-Aug.

Southern Australian Regions:
 Disturbed Periods: 15-16 Jul.
 Best Quiet Periods: 4-13 Jul, 18-Jul to 03-Aug.


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.
