SUBJ: ASWFC WEEKLY GEOPHYSICAL REPORT ISSUED ON 05 NOVEMBER 2026 FROM THE AUSTRALIAN SPACE WEATHER FORECASTING CENTRE ASWAS SCALE DESCRIPTION: https://bit.ly/3lmaMBx 1. SUMMARY (27 OCTOBER - 04 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 27 Oct 2221 1112 5 28 Oct 1122 0222 5 29 Oct 1110 0001 1 30 Oct 2231 2213 8 31 Oct 2223 3353 16 01 Nov 3324 4221 13 02 Nov 1123 1210 5 03 Nov 1211 1111 3 04 Nov 2233 3011 8 *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. G1 geomagnetic conditions were observed in the Australian region on 31-Oct. G0 on all other days. 2. FORECAST (05 NOVEMBER - 05 DECEMBER) Disturbed Periods: 7-8 Nov, 10-11 Nov, 17-18 Nov, 4-5 Dec. Best Quiet Periods: 5 Nov, 13-16 Nov, 20 Nov to 3 Dec. 3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS Northern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 5 Nov, 13-16 Nov, 20 Nov to 3 Dec. Central Australian Regions: Mildly Disturbed Periods: 7-11 Nov, 17-18 Nov, 4-5 Dec. Best Quiet Periods: 5 Nov, 13-16 Nov, 20 Nov to 3 Dec. Southern Australian Regions: Disturbed Periods: 7-11 Nov, 17-18 Nov, 4-5 Dec. Best Quiet Periods: 5 Nov, 13-16 Nov, 20 Nov to 3 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.
