The geomagnetic activity remained at quiet to active levels 
for the first three days of this period due to the effect of 
a coronal hole. It then gradually declined to unsettled and 
quiet levels. The effect of another small coronal hole raised 
the activity to unsettled levels on 14 June. 

2. FORECAST (15 JUNE - 15 JULY)
Disturbed Periods: 
Unsettled 27 to 28 June, active 04 to 05 July, unsettled 06 July. 

Best Quiet Periods: 
17 to 26 June, 29 June to 02 July, 07 to 11 July.

3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS

Northern Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 15 Jun to 11 Jul.

Central Australian Regions:
 Disturbed Periods: None.
 Best Quiet Periods: 15 Jun to 17 Jun,  22 Jun to 28 Jun,  1 Jul to 3 Jul,

Southern Australian Regions:
 Disturbed Periods: 4 Jul to 5 Jul.
 Best Quiet Periods:  17 Jun,  20 Jun to 28 Jun,   2 Jul,  7 Jul to 11 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.
