Quiet to unsettled conditions. Brief period of active conditions on
1 Dec. A weak (13 nT) impulse was observed at 1310 UT on 1 Dec in the

Disturbed Periods:
No strong recurrent patterns, however mild activity may be experienced on:
6-8 Dec, 12-13 Dec.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
Disturbed Periods: None.
Best Quiet Periods: 5-31 Dec.
Central Australian Regions:
Mildly Disturbed Periods: 6-7 Dec.
Best Quiet Periods: 5 Dec, 8-12 Dec, 15-31 Dec.
Southern Australian Regions:
Disturbed Periods: 6-7 Dec.

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.
