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. 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.

Geomagnetic Forecast

(last updated 28 Feb 2021 23:33 UT)

Date Ap Conditions 01 Mar 18 Quit to active with possible minor storm levels. 02 Mar 12 Quiet to active. 03 Mar 9 Quiet to Unsettled COMMENT: SWS Geomagnetic Warning 8 was issued on 28 February and is current for 1-2 Mar. On UT day 28 February, mostly quiet conditions were observed in the Australian region. Quiet to storm levels were observed in the Antarctic region. On UT day 1 March geomagnetic activity is expected to be quiet to active with possible minor storm periods due to coronal hole effects. Quiet to active levels are expected on UT day 2 March with quiet to unsettled conditions on UT day 3 March.
