SUBJ: ASWFC WEEKLY GEOPHYSICAL REPORT ISSUED ON 12 NOVEMBER 2026 FROM THE AUSTRALIAN SPACE WEATHER FORECASTING CENTRE ASWAS SCALE DESCRIPTION: https://bit.ly/3lmaMBx 1. SUMMARY (03 NOVEMBER - 11 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 03 Nov 1211 1111 3 04 Nov 2233 3011 8 05 Nov 1120 2122 4 06 Nov 1122 2223 7 07 Nov 2133 2343 13 08 Nov 3333 3332 14 09 Nov 2323 2222 9 10 Nov 2323 1212 8 11 Nov 1122 1231 6 *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. G0 geomagnetic conditions were observed in the Australian region over 03-11 Nov. 2. FORECAST (12 NOVEMBER - 12 DECEMBER) Disturbed Periods: 17-18 Nov, 27-28 Nov. 04-05 Dec. Best Quiet Periods: 12-16 Nov, 19-26 Nov, 29-Nov to 03-Dec, 06-12 Dec. 3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS Northern Australian Regions: Disturbed Periods: 05-06 Dec. Best Quiet Periods: 12-Nov to 03-Dec, 08-12 Dec. Central Australian Regions: Mildly Disturbed Periods:04-Dec, 07-09 Dec. Disturbed Periods: 05-06 Dec. Best Quiet Periods: 12 Nov to 02-Dec, 11-12 Dec. Southern Australian Regions: Disturbed Periods: 04-09 Dec. Best Quiet Periods: 12 Nov to 02-Dec, 11-12 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.
