cooperation with the following organisations: Geoscience Australia,
University of Newcastle Space Physics Group, Australian Government
Antarctic Division and International Center for Space Weather
Science and Education, Japan.
Active on 19-20 Feb, 23 Feb. Quiet to unsettled on other days.
2. FORECAST (27 FEBRUARY - 29 MARCH)
Disturbed Periods:
No strong recurrent patterns, however mild activity may be experienced on:
27 Feb, 1 Mar, 7 Mar, 9 Mar, 20 Mar.
Best Quiet Periods:
28 Feb, 2-6 Mar, 8 Mar, 10-19 Mar, 21-25 Mar.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS - based on recurrence
Northern Australian Regions: NA
Central Australian Regions:
Mildly Disturbed Periods: 19th March
Best Quiet Periods: 27 Feb to 18 Mar, 20-29 March.
Southern Australian Regions:
Disturbed Periods: 19th March
Best Quiet Periods: 27 Feb to 7 Mar, 10-18 Mar, 20-25 Mar.
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.
