Active on 6 Nov. Minor storm on 4 Nov.  Quiet to unsettled on other days.

2. FORECAST (11 NOVEMBER - 11 DECEMBER)
Disturbed Periods: 
No strong recurrent patterns, however mild activity may be experienced on:
 13-15 Nov,  26-30 Nov,  2-3 Dec.

Best Quiet Periods: 
 11-12 Nov,  16-25 Nov,  4-6 Dec.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 11-15 Nov, 19- 27 Nov, 4-7 Dec.

Central Australian Regions:
 Mildly disturbed Periods: 17 Nov, 30 Nov-1 Dec
 Best Quiet Periods: 11-12 Nov, 19- 27 Nov, 4-7 Dec.

Southern Australian Regions:
 Disturbed Periods: 17 Nov, 30 Nov - 1 Dec.
 Best Quiet Periods: 11-12 Nov,  19-27 Nov,  4-7 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.
