SUBJ: SWS AURORA WATCH
ISSUED AT 2351 UT ON 28 Oct 2021 by Space Weather Services
FROM THE AUSTRALIAN SPACE FORECAST CENTRE

AR2887 produced X1.0 flare at 28/1535 UT, which triggered a halo CME.
The CME is expected to arrive at Earth in the first half of UT day 30
October. As a result, the geomagnetic conditions are expected to reach
major storm levels with a chance of severe storm periods. On the local
night of 30 October (and maybe 31 October), aurora may be visible from
Tasmania, the coastline of Victoria and the southwest coast of Western
Australia. Aurora alerts will follow if significant geomagnetic
activity actually occurs.
