SUBJ: ASWFC WEEKLY GEOPHYSICAL REPORT ISSUED ON 11 APRIL 2024 FROM THE AUSTRALIAN SPACE WEATHER FORECASTING CENTRE ASWAS SCALE DESCRIPTION: https://bit.ly/3lmaMBx 1. SUMMARY (02 APRIL - 10 APRIL) 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 02 Apr 1113 1121 5 03 Apr 2211 2100 3 04 Apr 1133 2223 9 05 Apr 2323 3222 10 06 Apr 2232 2212 7 07 Apr 1212 2221 5 08 Apr 2222 0000 3 09 Apr 1122 2112 5 10 Apr 2221 2211 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. Quiet to unsettled conditions. 2. FORECAST (11 APRIL - 11 MAY) Disturbed Periods: 19-20 Apr, 01-03 May Best Quiet Periods: 11-16 Apr, 23-30 Apr, 04-11 May 3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS Northern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 11-16 Apr, 23-30 Apr, 04-11 May Central Australian Regions: Disturbed Periods: None. Mildly disturbed periods: 19-20 Apr Best Quiet Periods: 11-26 Apr, 23-30 Apr, 04-11 May. Southern Australian Regions: Disturbed Periods: 19-20 Apr Mildly Disturbed Periods: 01-03 May Best Quiet Periods: 11-16 Apr, 23-30 Apr, 04-11 May 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.
