Science and Education, Japan.
Active on 8 Jun. Quiet to unsettled on other days.
2. FORECAST (12 JUNE - 12 JULY)
Disturbed Periods:
No strong recurrent patterns, however mild activity may be experienced on:
13-14 Jun, 18-19 Jun, 26 Jun, 5-9 Jul.
Best Quiet Periods:
12 Jun, 15-17 Jun, 20-25 Jun, 27 Jun to 4 Jul, 10-12 Jul.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
Disturbed Periods: None.
Best Quiet Periods: 12 Jun to 12 Jul.
Central Australian Regions:
Disturbed Periods: None.
Best Quiet Periods: 12 Jun to 4 Jul, 10-12 Jul.
Southern Australian Regions:
Disturbed Periods: 5-9 Jul.
Best Quiet Periods: 12 Jun to 4 Jul, 10-12 Jul.
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.
