Aurora Alert-Aurora watch tonight (8 September)

The Australian IPS has just issued an aurora alert for high latitudes and the NOAA site a G2 storm current BUT of course it is daytime still. Whether it will persist into dark hours here in Australia is uncertain. Currentlt the magnetic field is relentlessly northward, which does not bode well for Australian aurora, but it may  have episodes of southward deflection during the evening. (there is also a geomagnetic alert current)

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 Northern Tasmania at Cressy may be helpful.
