G0 geomagnetic conditions were observed this week. 

2. FORECAST (21 NOVEMBER - 21 DECEMBER)
Disturbed Periods: 
 11-12 Dec.

 27-28 Nov, 4 Dec, 9-10 Dec, 13-15 Dec, 18 Dec.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: NA

Central Australian Regions:
 Mildly Disturbed Periods: 24 Nov, 26-27 Nov, 21 Dec.
 Best Quiet Periods: 21-22 Nov, 29 Nov to 19 Dec.

Southern Australian Regions:
 Disturbed Periods: 24 Nov, 26-27 Nov, 21 Dec.
 Best Quiet Periods: 21-22 Nov, 29 Nov to 19 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.
