SUBJ: SWS AURORA WATCH
ISSUED AT 0117 UT ON 21 Apr 2018 by Space Weather Services
FROM THE AUSTRALIAN SPACE FORECAST CENTRE

The solar wind is currently under the influence of a high speed solar
wind stream from a recurrent coronal hole. Geomagnetic activity
reached storm levels on April 20 and is forecast to be at unsettled to
active levels on April 21, with possible isolated minor storm periods.
If significant geomagnetic activity occurs, there will be a chance of
visible auroras for southernmost Australian regions (e.g., Tasmania
and coastline of Victoria) during local nighttime hours. Aurora alerts
will follow if significant geomagnetic activity actually occurs. Visit
the SWS Aurora webpage http://www.sws.bom.gov.au/Aurora for current
aurora viewing conditions.
