SUBJ: ASWFC WEEKLY GEOPHYSICAL REPORT ISSUED ON 11 JULY 2024 FROM THE AUSTRALIAN SPACE WEATHER FORECASTING CENTRE ASWAS SCALE DESCRIPTION: https://bit.ly/3lmaMBx 1. SUMMARY (02 JULY - 10 JULY) 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 Jul 1110 0001 1 03 Jul 0110 0001 1 04 Jul 1121 2322 6 05 Jul 1422 2210 7 In the BOM magnetometer data for 05 Jul, a weak (10nT) impulse was observed at 0512UT. 06 Jul 1010 0001 1 07 Jul 1110 0011 1 08 Jul 2222 3121 7 09 Jul 1111 1011 2 10 Jul 1220 0201 3 *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 all week. 2. FORECAST (11 JULY - 10 AUGUST) Disturbed Periods: No strong recurrent patterns, however mild activity may be experienced on: 12-14 Jul, 8-10 Aug. Best Quiet Periods: 16-23 Jul, 29-31 Jul, 2-6 Aug. 3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS Northern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 15 Jul to 6 Aug. Central Australian Regions: Disturbed Periods: None. Mildly Disturbed Periods: 13-14 Jul. Best Quiet Periods: 16 Jul to 6 Aug. Southern Australian Regions: Disturbed Periods: None. Mildly Disturbed Periods: 12-15 Jul, 8-10 Aug. Best Quiet Periods: 17 Jul to 6 Aug. 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.
