*estimated from real time data
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.
22-30 Sep: Quiet to unsettled conditions.
2. FORECAST (01 OCTOBER - 31 OCTOBER)
Geomagnetic conditions may reach active levels during 2-3 Oct
due to the arrival of the transition region between slow and
fast solar wind.
2-3 Oct, 12 Oct, 17 Oct, 20 Oct.
Best Quiet Periods:
1 Oct, 4 Oct, 6 Oct, 8 Oct, 23-26 Oct.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
Disturbed Periods: None.
Central Australian Regions:
Disturbed Periods: 4 Oct, 8-9 Oct, 17-19 Oct.
Southern Australian Regions:
Disturbed Periods: 2-3 Oct, 4 Oct, 8-9 Oct, 17-19 Oct.
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
Geomagnetic activity can frequently be determined by short timescale
solar events that cannot be forecast a week in advance, particularly
at solar maximum.
