 27 Aug   1132 2222    7  In the BOM magnetometer data for 27 
                          Aug, a weak (11nT) impulse was observed 
                          at 0842UT.

*estimated from real time data

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-Aug due to sustained
periods of southward IMF conditions following a CME arrival on 27-Aug.
G0 geomagnetic conditions were observed on all other days. 

2. FORECAST (29 AUGUST - 28 SEPTEMBER)
Disturbed Periods: 
 24 Sep.

Best Quiet Periods: 
 2-3 Sep,  5-6 Sep,  11 Sep,  13 Sep,  21-22 Sep.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 29 Aug to 28 Sep.

Central Australian Regions:
 Mildly Disturbed Periods: None.
 Best Quiet Periods: 29 Aug to 28 Sep.

Southern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 29 Aug to 28 Sep.

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.
