SUBJ: SWS WEEKLY GEOPHYSICAL REPORT ISSUED ON 02 JULY 2020, BY Space Weather Services, FROM THE AUSTRALIAN SPACE FORECAST CENTRE 1. SUMMARY (23 JUNE - 01 JULY) K indices are in UT (0-24). For conversion to local time: AEST = UT + 10 hours; ACST = UT + 9.5 hours; AWST = UT + 8 hours Australian Region* Date K-INDICES A 23 Jun 0000 0000 0 24 Jun 1111 0000 1 25 Jun 0100 0001 0 26 Jun 1100 1022 2 27 Jun 2122 2001 4 28 Jun 1100 0000 0 29 Jun 1100 0000 0 30 Jun 2110 0001 2 01 Jul 1110 0011 1 *estimated from real time data NOTE: Indices may have been generated from data obtained in cooperation with the following organisations: Geoscience Australia, University of Newcastle Space Physics Group, Australian Government Antarctic Division and International Center for Space Weather Science and Education, Japan. Mostly quiet conditions. 2. FORECAST (02 JULY - 01 AUGUST) Disturbed Periods: No strong recurrent patterns. No significant disturbances expected. Best Quiet Periods: 5-6 Jul, 8-27 Jul. 3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS Northern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 02 July-01 August Central Australian Regions: Disturbed Periods: None. Best Quiet Periods: 02 July-01 August Southern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 02 July-01 August 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.
