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 12 Aug 2026 23:30 UT)

Date Ap Conditions 13 Aug 6 G0 14 Aug 12 G0 15 Aug 14 G0 COMMENT: G0 geomagnetic conditions were observed on UT day 12-Aug. G0 geomagnetic conditions are expected over 13-15 Aug. A small coronal hole may connect with the Earth by late 14-Aug or else on 15-Aug to enhance the solar wind speed, but not expected to induce any significant activity.
