NOTE: Indices may have been generated from data obtained in
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.
Mostly quiet to unsettled conditions observed during the week,
with coronal hole wind stream induced mild isolated active periods
05-06 March.
2. FORECAST (10 MARCH - 09 APRIL)
Disturbed Periods:
mild activity on late 10-11 and 12 Mar, 1-2 Apr.
Best Quiet Periods:
14-18 Mar, 22-25 Mar, 27-30 Mar, 3-5 Apr.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: NA
Central Australian Regions: NA
Southern Australian Regions:
Disturbed Periods: None, mild activity late 10-11 and 12 Mar, 1-2 Apr.
Best Quiet Periods: 14-18 Mar, 21-25 Mar, 27-31 Mar, 3-5 and 9 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.
