                          Aug, a weak (16nT) impulse was observed 
                          at 1425UT and a possible weak (24nT) impulse 
                          was observed at 1726UT.

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 conditions briefly observed on 17-Aug. Planetary conditions
reached G3. This activity was associated with a CME arrival from
an X1 (R3) flare on 14-Aug. G0 conditions on other days.

2. FORECAST (22 AUGUST - 21 SEPTEMBER)
Disturbed Periods: None.

Best Quiet Periods: 
 29-30 Aug, 1-6 Sep,  10-11 Sep,  15-17 Sep.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 22 Aug to 17 Sep.

Central Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 22 Aug to 17 Sep.

Southern Australian Regions:
 Disturbed Periods: None
 Best Quiet Periods: 22 Aug to 17 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.
