Aurora Happening Now (7 November, 10:00 AEDST)
UPDATED: 11:30 pm AEDST. Still ongoing in in some places in TAS, reports from Victoria as well.
Unaided eye aurora (and beams) have been reported as of a few minutes ago in Tasmania (Ulverstone, Howden, Murdunna),and South Australia (Victor Harbour), camera only at Stoodly and goats bluff Tas. Cloud has come in for some places but still worth looking 562 km/sec Bz: -7.0 nT Density = 1.0 p/cc , Lanceston Kindex currently 5. It is likely that there will be bursts of auroral activity during the night as the solar wind intensity and Bz fluctuates.
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.
Here is the near-real time satellite view of the clouds http://satview.bom.gov.au/
Cloud cover predictions can be found at SkippySky.
The all sky aurora camera in Northern Tasmania at Cressy may be helpful.

Ian look at this video. Is this a good example of a Atmospheric refraction?
