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 Sep 2022 23:30 UT)
Date Ap Conditions 01 Oct 30 G0-G1, chance of G2 02 Oct 36 G0-G1, chance of G2 03 Oct 20 G0-G1 COMMENT: ASWFC Geomagnetic Warning 45 was issued on 28 September and is current for 30 Sep to 2 Oct. G0 geomagnetic conditions were observed in the Australian region on UT day 30-Sep. Mostly G0-G1 geomagnetic conditions were observed in the Antarctic region, with an isolated period of G2 at Casey. Mostly G1 geomagnetic conditions are expected over 01-Oct, with a chance of G2, due to the combination of a coronal hole high speed wind stream and impact from a CME first observed 28-Sep. A second coronal hole high speed wind stream is expected to become geoeffective over 02-03 Oct, likely producing further G1, possibly G2, geomagnetic conditions.
