SUBJ: SWS WEEKLY GEOPHYSICAL REPORT ISSUED ON 19 NOVEMBER 2020, BY Space Weather Services, FROM THE AUSTRALIAN SPACE FORECAST CENTRE 1. SUMMARY (10 NOVEMBER - 18 NOVEMBER) 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 10 Nov 1110 0000 1 11 Nov 0000 1222 3 12 Nov 1122 1011 3 13 Nov 1110 1011 2 14 Nov 0110 1011 1 15 Nov 1100 0101 1 16 Nov 1100 1001 1 17 Nov 1001 1001 1 18 Nov 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. Quiet to unsettled conditions. 2. FORECAST (19 NOVEMBER - 19 DECEMBER) Disturbed Periods: No strong recurrent patterns, however mild activity may be experienced on: 22-25 Nov Best Quiet Periods: 19-21 Nov, 26 Nov - 19 Dec. 3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS Northern Australian Regions: NA Central Australian Regions: Disturbed Periods: None. Best Quiet Periods: 19-22 Nov, 24 Nov to 15 Dec. Southern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 24 Nov to 15 Dec. 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.
