                          Feb, a weak (10nT) impulse was observed 
                          at 1145UT and a weak (8nT) impulse 
                          was observed at 1334UT.

G0 geomagnetic conditions were observed this week.

2. FORECAST (06 MARCH - 05 APRIL)
Disturbed Periods:

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 6 Mar to 5 Apr.

Central Australian Regions:
 Mildly Disturbed Periods: 9-11 Mar, 13-15 Mar, 26-29 Mar, 5 Apr.
 Best Quiet Periods: 17-24 Mar,  31 Mar to 3 Apr.

Southern Australian Regions:
 Disturbed Periods: 9-11 Mar, 13-15 Mar, 26-29 Mar, 5 Apr.
 Best Quiet Periods: 17-24 Mar,  31 Mar to 3 Apr.

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.
