2. FORECAST (31 JANUARY - 02 MARCH)
Disturbed Periods:
No strong recurrent patterns, however mild activity may be experienced on:
31 Jan to 2 Feb, 19 to 21 Feb, 27 Feb to 01 Mar.
Best Quiet Periods:
4 to 18 Feb, 22 to 26 Feb.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: NA
Central Australian Regions:
Mildly disturbed periods: 31 Jan to 02 Feb, 20-21 Feb
Best Quiet Periods: 03 to 11 Feb, 13 to 18 Feb, 23 to 26 Feb
Southern Australian Regions:
Disturbed Periods: 31 Jan to 02 Feb, 20 to 21 Feb
Best Quiet Periods: 03 to 11 Feb, 13 to 18 Feb, 23 to 26 Feb.
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.
