SUBJ: SWS WEEKLY GEOPHYSICAL REPORT ISSUED ON 13 JUNE 2019, BY Space Weather Services, FROM THE AUSTRALIAN SPACE FORECAST CENTRE 1. SUMMARY (04 JUNE - 12 JUNE) 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 04 Jun 1211 1211 4 05 Jun 1110 0000 1 06 Jun 0000 0000 0 07 Jun 0011 1210 2 08 Jun 0002 2442 9 In the SWS magnetometer data for 08 Jun, a weak (7nT) impulse was observed at 1001UT. 09 Jun 2111 1100 2 10 Jun 0000 1010 0 11 Jun 1100 0000 0 12 Jun 1101 1000 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. Quiet to unsettled conditions. 2. FORECAST (13 JUNE - 13 JULY) Disturbed Periods: No strong recurrent patterns, however mild activity may be experienced on: 13 Jun, 23-26 Jun. Best Quiet Periods: 14-22 Jun, 27 Jun to 4 Jul. 3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS Northern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 14-21 June, 27 June to 3 Jul. Central Australian Regions: Mildly disturbed Periods: None. Best Quiet Periods: 14-21 June, 27 June to 3 Jul. Southern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 14-21 June, 27 June to 3 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.
