CME arrivals 27-28 Jan.
2. FORECAST (30 JANUARY - 01 MARCH)
Disturbed Periods:
1-3 Feb.
Best Quiet Periods:
30-Jan, 7-10 Feb, 14 Feb, 17-Feb, 20-23 Feb.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions: NA
Central Australian Regions: NA
Southern Australian Regions:
Disturbed Periods: 01-03 Feb, 13-14 Feb, 16-17 Feb.
Best Quiet Periods: 7-8 Feb, 19-25 Feb.
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.
