SUBJ: ASWFC WEEKLY GEOPHYSICAL REPORT ISSUED ON 14 MARCH 2024 FROM THE AUSTRALIAN SPACE WEATHER FORECASTING CENTRE ASWAS SCALE DESCRIPTION: https://bit.ly/3lmaMBx 1. SUMMARY (05 MARCH - 13 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 05 Mar 2221 1111 4 06 Mar 1212 2101 4 07 Mar 3233 2332 12 In the BOM magnetometer data for 07 Mar, a weak (11nT) impulse was observed at 0105UT and a weak (9nT) impulse was observed at 0733UT. 08 Mar 2321 2113 7 09 Mar 3222 2122 7 10 Mar 1122 0321 5 11 Mar 1111 1102 3 12 Mar 2112 1201 4 13 Mar 2032 2311 7 *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 this week. 2. FORECAST (14 MARCH - 13 APRIL) Disturbed Periods: 14 Mar. Best Quiet Periods: 16-22 Mar, 26-27 Mar, 29 Mar to 2 Apr, 7-8 Apr. 3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS Northern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 14 Mar to 13 Apr. Central Australian Regions: Mildly Disturbed Periods: None. Best Quiet Periods: 14 Mar to 13 Apr. Southern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 14 Mar to 13 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.
