Aurora Watch Tonight (Sunday 16 August 2015)

UPDATE: 7:00 pmConfirmed aurora from Batemans bay and Bicheno Tas just now. Not clear if unaided eye or camera only. Seems to be sporadic, flaring up and dying down. 

The Australian IPS has just issued an aurora alert for high latitudes BUT despite a good southward magnetic field -8 nT the Launceston  Kindex is 5 and the NOAA site a G2 storm current (and a G1 storm predicted later). I leave it up to you folks to decide if it is worthwhile.
Currently, the Kindex is 5. Velocity: 534 km/sec Bz: -5.0 nT Density = 4.0 p/cc

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 storm is unlikely to produce aurora as good as seen last night, which was visible from Southern South Australia and Northern Victoria, with beams "fenceposts" and proton arcs even! Still, Tasmanian and Southern Victoria should be on alert!

The all sky aurora camera in Northern Tasmania at Cressy may be helpful.
