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 30 Jan 2025 23:35 UT)
Date Ap Conditions 31 Jan 16 G0, chance of G1 periods 01 Feb 20 G0-G1 02 Feb 20 G0-G1 COMMENT: ASWFC Geomagnetic Warning 6 was issued on 29 January and is current for 31 Jan to 1 Feb. G0 geomagnetic conditions were observed in the Australian region on UT day 30-Jan. G0 geomagnetic conditions were generally observed in the Antarctic region, with an isolated G1 period observed at Casey. G0, chance G1 geomagnetic conditions are expected for 31-Jan with an isolated G1 period possible early in the UT day following a very weak CME transit, then later in the UT day G1 periods may be experienced due to the onset of coronal hole high speed solar wind streams from a pair of coronal holes.
