SUBJ: IPS AURORA WATCH
ISSUED AT 0001 UT ON 19 Apr 2014 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE

Two Coronal Mass Ejections, the first slow and weak but the second
faster and stronger are expected to impact the Earth. The first is
expected sometime after midday on the 20th of April AEST, with the
second expected around midnight on the 20th. Note that arrival times
are generally uncertain by +/- 6 hours or so. The first event on its
one would not warrant an aurora watch however the second would in its
own right and the combination of the two may amplify the effects of
the second. Auroral activity visible from Tasmania and possibly
further north in Australia is expected from this event, should the
arrival time coincide with local nighttime as anticipated. Aurora
alerts will follow should favourable space weather activity
eventuate.
