G1 geomagnetic conditions were observed on 28-Jun due to a CME arrival.
G0 geomagnetic conditions were observed on all other days.
2. FORECAST (04 JULY - 03 AUGUST)
Disturbed Periods:
No strong recurrent patterns, however mild activity may be experienced on:
7-8 Jul, 12-17 Jul, 22-27 Jul.
Best Quiet Periods:
5-6 Jul, 9-11 Jul, 18-19 Jul, 21 Jul, 28-30 Jul.
3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS
Northern Australian Regions:
Disturbed Periods: None.
Best Quiet Periods: 4-Jul to 03-Aug.
Central Australian Regions:
Mildly Disturbed Periods: 15-16 Jul.
Best Quiet Periods: 4-13 Jul, 18-Jul to 03-Aug.
Southern Australian Regions:
Disturbed Periods: 15-16 Jul.
Best Quiet Periods: 4-13 Jul, 18-Jul to 03-Aug.
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.
