No strong recurrent patterns, however mild activity may be experienced on:
18-19 Dec.
Best Quiet Periods:
3 Dec to 17 Dec, 20 Dec to 29 Dec.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Central Australian Regions: Mildly Disturbed 18-19Dec
Southern Australian Regions: Disturbed 18-19Dec
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.
