SUBJ: SWS WEEKLY GEOPHYSICAL REPORT ISSUED ON 16 JULY 2020, BY Space Weather Services, FROM THE AUSTRALIAN SPACE FORECAST CENTRE 1. SUMMARY (07 JULY - 15 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 07 Jul 0110 0000 0 08 Jul 0000 0001 0 09 Jul 1111 1000 1 10 Jul 0110 0000 0 11 Jul 0100 0000 0 12 Jul 0001 1000 0 13 Jul 1222 0122 5 14 Jul 3231 1100 5 15 Jul 0121 3200 4 *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 with some unsettled periods on 14 and 15 July. 2. FORECAST (16 JULY - 15 AUGUST) Disturbed Periods: No strong recurrent patterns, however mild activity may be experienced on: 31 Jul to 01 Aug, 09 to 10 Aug. Best Quiet Periods: 16 to 30 Jul, 02 to 09 Aug, 12 to 15 Aug. 3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS Northern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 16 Jul to 15 Aug. Central Australian Regions: NA Disturbed Periods: None. Best Quiet Periods: 16 Jul to 15 Aug. Southern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 16 Jul to 31 Jul, 03 to 15 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.
