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 10 Dec 2023 23:30 UT)

Date Ap Conditions 11 Dec 14 G0, slight chance G1 12 Dec 13 G0, slight chance G1 13 Dec 10 G0 COMMENT: G0 geomagnetic conditions were observed in the Australian region on UT day 10-Dec. Mostly G0 geomagnetic conditions were observed in the Antarctic region, with an isolated period of G1 observed at Casey. G0 geomagnetic conditions are expected over 11-13 Dec, with a mild increase in geomagnetic activity expected due to a coronal hole wind stream.
