SUBJ: ASWFC WEEKLY GEOPHYSICAL REPORT ISSUED ON 05 MARCH 2026 FROM THE AUSTRALIAN SPACE WEATHER FORECASTING CENTRE ASWAS SCALE DESCRIPTION: https://bit.ly/3lmaMBx 1. SUMMARY (24 FEBRUARY - 04 MARCH) 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 24 Feb 2323 3222 10 25 Feb 3232 3323 12 26 Feb 2232 2222 8 27 Feb 2212 3312 8 28 Feb 2211 3112 6 01 Mar 2121 2112 5 02 Mar 1110 1011 2 03 Mar 1222 2323 8 04 Mar 2222 1112 5 *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. Geomagnetic activity was at the G0 level in the Australian region throughout out the period of 24-Feb to 04-Mar. 2. FORECAST (05 MARCH - 04 APRIL) Disturbed Periods: 07-09 Mar, 14-16 Mar, 20-24 Mar, 03-04 Apr. Best Quiet Periods: 05-06 Mar, 11-13 Mar, 18-19 Mar, 26-Mar to 01-Apr. 3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS Northern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 05-13 Mar, 16-20 Mar, 23-Mar to 05-Apr. Central Australian Regions: Slightly Disturbed Periods: 14-15 Mat, 21-22 Mar. Best Quiet Periods: 05-12 Mar, 17-20 Mar, 24 Mar to 05-Apr. Southern Australian Regions: Disturbed Periods: 07-09 Mar, 14-16 Mar, 20-25 Mar, 03-04 Apr. Best Quiet Periods: 05-06 Mar, 11-12 Mar, 18-19 Mar, 26-Mar to 01-Apr. 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.
