Aurora Watch (17-18 May)
Aurora can occur at any time after nightfall (although around midnight or just after seems to be common). Dark sky sites have the best chance of seeing anything, and always allow around 5 minutes for your eyes to become dark adapted.
As always look to the south for shifting red/green glows, beams have been reported consistently over the last few aurora and a large green "blob" has been seen.
The all sky aurora camera in Southern Tasmania at Cressy may be helpful.

ISSUED AT 2309UT/15 MAY 2015
BY THE AUSTRALIAN SPACE FORECAST CENTRE.
Combined coronal hole and CME glancing blow effects are expected
to produce disturbed geomagnetic conditions from 17-May.
INCREASED GEOMAGNETIC ACTIVITY EXPECTED
DUE TO CORONAL MASS EJECTION AND CORONAL HOLE
FROM 17-18 MAY 2015
GEOMAGNETIC ACTIVITY FORECAST

SUBJ: IPS AURORA WATCH
ISSUED AT 2330 UT ON 15 May 2015 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
A glancing blow from a Coronal Mass Ejection is expected to impact the
Earth from late on 17-May. This, combined with coronal hole effects,
could result in significant space weather activity and visible auroras
during local nighttime hours on 17-May. Aurora alerts will follow
should favourable space weather activity eventuate.
