2. FORECAST (27 MARCH - 26 APRIL)
Disturbed Periods:
No strong recurrent patterns, however mild activity may be experienced on:
9 Apr, 17 Apr.
Best Quiet Periods:
27 Mar to 8 Apr, 10-16 Apr, 18-27 Apr.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: NA
Central Australian Regions: NA
Southern Australian Regions:
Disturbed Periods: None.
Best Quiet Periods: 27 Mar to 26 Apr.
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.
