SUBJ: SWS WEEKLY GEOPHYSICAL REPORT ISSUED ON 14 FEBRUARY 2019, BY Space Weather Services, FROM THE AUSTRALIAN SPACE FORECAST CENTRE 1. SUMMARY (05 FEBRUARY - 13 FEBRUARY) 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 Feb 2110 0111 2 06 Feb 2222 2222 7 07 Feb 1110 1102 2 08 Feb 2112 1222 5 09 Feb 2222 2221 6 10 Feb 2211 1111 4 11 Feb 1111 3322 7 12 Feb 2111 1002 3 13 Feb 1224 3322 11 *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 (14 FEBRUARY - 16 MARCH) Disturbed Periods: No strong recurrent patterns, however mild activity may be experienced on: 14-15 Feb, 18-22 Feb, 27 Feb to 3 Mar, 12-14 Mar. Best Quiet Periods: 16-17 Feb, 23-25 Feb, 4-11 Mar. 3. FORECAST FOR HIGH RESOLUTION AEROMAGNETIC SURVEYS Northern Australian Regions: Disturbed Periods: None. Best Quiet Periods: 16-17 Feb, 23-25 Feb, 4-11 Mar. Central Australian Regions: Disturbed Periods: None. Mildly disturbed periods: 14 Feb, 19-23 Feb, 28 Feb to 2 Mar. Best Quiet Periods: 17 Feb, 23-25 Feb, 4-11 Mar. Southern Australian Regions: Disturbed Periods: 14 Feb, 19-23 Feb, 28 Feb to 2 Mar. Best Quiet Periods: 17 Feb, 23-25 Feb, 4-11 Mar. 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.
