SUMMARY (18 JUNE - 26 JUNE) K indices are in UT (0-24).

G0 2. FORECAST (27 JUNE - 27 JULY) Disturbed Periods: No strong recurrent patterns, however mild activity may be experienced on: 28-30 Jun, 4-5 Jul, 12-15 Jul. Best Quiet Periods: 27 Jun, 1-2 Jul, 7-10 Jul, 17-22 Jul, 18-19 Jul, 25-27 Jul. 3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS Northern Australian Regions: Disturbed Periods: None. Mildly Disturbed Periods: None. Best Quiet Periods: 1 Jul to 23 Jul. Central Australian Regions: Disturbed Periods: None. Mildly Disturbed Periods: 28-30 Jun, 12-Jul Best Quiet Periods: 1-3 Jul, 6-10 Jul, 17-22 Jul, 25-27 Jul. Southern Australian Regions: Disturbed Periods: None. Mildly Disturbed Periods: 28-30 Jun, 12-Jul Best Quiet Periods: 1-3 Jul, 6-10 Jul, 17-22 Jul, 25-27 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.
