SUBJ: SWS WEEKLY GEOPHYSICAL REPORT ISSUED ON 23 JANUARY 2020, BY Space Weather Services, FROM THE AUSTRALIAN SPACE FORECAST CENTRE 1. SUMMARY (14 JANUARY - 22 JANUARY) 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 14 Jan 1111 0101 2 15 Jan 1112 1112 4 16 Jan 2222 1001 4 17 Jan 1120 1211 3 18 Jan 2210 0002 3 19 Jan 1100 0012 2 20 Jan 1110 0001 1 21 Jan 1112 2222 5 22 Jan 1212 1022 4 *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 (23 JANUARY - 22 FEBRUARY) Disturbed Periods: No strong recurrent patterns, however mild activity may be experienced on: 5 Feb. Best Quiet Periods: 23 Jan to 4 Feb, 6-18 Feb. 3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS Northern Australian Regions: NA Central Australian Regions: Mildly Disturbed Periods: 05-07 Feb Best Quiet Periods: 23 Jan - 04 Feb, 08 Feb - 22 Feb Southern Australian Regions: Disturbed Periods: 05-07 Feb Best Quiet Periods: 23 Jan - 04 Feb, 08 Feb - 22 Feb 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.
