2. FORECAST (14 AUGUST - 13 SEPTEMBER)
No strong recurrent patterns, however mild activity may be experienced on:
18 Aug to 20 Aug, 5 Sep to 6 Sep
Best Quiet Periods:
14 Aug to 17 Aug, 21 Aug to 4 Sep, 7 Sep to 13 Sep.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Southern Australian Regions:
Disturbed Periods: None.
Best Quiet Periods: 14 Aug to 16 Aug, 20 Aug to 2 Sep, 7 Sep.
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.
