SUBJ: ASWFC WEEKLY GEOPHYSICAL REPORT ISSUED ON 24 OCTOBER 2024 FROM THE AUSTRALIAN SPACE WEATHER FORECASTING CENTRE ASWAS SCALE DESCRIPTION: https://bit.ly/3lmaMBx 1. SUMMARY (15 OCTOBER - 23 OCTOBER) 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 15 Oct 2232 3323 11 16 Oct 2222 3323 10 17 Oct 2220 0122 4 18 Oct 2201 3233 8 19 Oct 3333 3233 14 20 Oct 2111 1011 3 21 Oct 1111 1212 4 In the BOM magnetometer data for 21 Oct, a weak (9nT) impulse was observed at 1538UT. 22 Oct 1122 2222 6 23 Oct 2213 2012 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. Quiet to unsettled conditions. 2. FORECAST (24 OCTOBER - 23 NOVEMBER) Disturbed Periods: 26 Oct, 3-4 Nov, 18-19 Nov. Best Quiet Periods: 24-Oct, 28-31 Oct, 1-Nov, 10-18 Nov. 3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS Northern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 24-Oct, 28-31 Oct, 1-Nov, 10-19 Nov. Central Australian Regions: Disturbed Periods: None. Mildly Disturbed Periods: 3-4 Nov Best Quiet Periods: 24-Oct, 29-31 Oct,1-Nov, 10-18 Nov. Southern Australian Regions: Disturbed Periods: 3-4 Nov. Mildly Disturbed Periods: 26-27 Oct, 18-19 Nov Best Quiet Periods: 24 Oct, 28-Oct to 1 Nov, 10-17 Nov 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.
