*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.
Active on 13-14 Nov. Quiet to unsettled on other days.
2. FORECAST (15 NOVEMBER - 15 DECEMBER)
Disturbed Periods:
No strong recurrent patterns, however mild activity may be experienced on:
15 Nov, 28 Nov, 4 Dec, 10 Dec.
Best Quiet Periods:
16-27 Nov, 29 Nov to 3 Dec, 5-9 Dec, 11 Dec.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: None.
Central Australian Regions:
Disturbed Periods: None.
Best Quiet Periods: 15-21 Nov, 27-29 Nov, 1-11 Dec.
Southern Australian Regions:
Disturbed Periods: None.
Best Quiet Periods: 15-21 Nov, 27-29 Nov, 1-8 Dec.
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.
