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 Aug 2026 23:30 UT)

Date Ap Conditions 11 Aug 14 G0, chance of G1 12 Aug 18 G0, chance of G1 13 Aug 8 G0 COMMENT: G0 geomagnetic conditions were observed in the Australian, planetary and Antarctic regions on UT day 10-Aug. G0 planetary geomagnetic conditions are expected over 11-13 Aug, with a chance of G1 over 11-12 Aug due to a combination of high speed wind stream effects from multiple small coronal holes and two anticipated glancing CME arrivals.
