Aurora visible NOW (15 August)

Aurora are Happening NOW. Unaided eye Aurora and beams have been reported in Tasmania, from a wide variety of locations, Inverlock Victoria and some faint camera only colour in South Australia.

UPDATE 10:33: Still ongoing in Tassie, camera only colour at Mornington Vic  with fog (colour from Melbourne's western suburbs at 10 pm AEST), unaided eye visible at Rickettes Point Vic. The IPS has just issued and Aurora Alert (well after people were seeing them)
UPDATE 11:16: Still ongoing Tassie, Bacchus Marsh Victoria and South Australia (south of Port Lincoln).

An Aurora Alert and a geomagnetic alert had been issued by the Australian  IPS for the 16th due to an anticipated impact from a coronal mass ejection, this activity is possibly due to its early arrival.
Currently, the Kindex is 5. Velocity: 453 km/sec Bz: -7.0 nT Density = 26.0 p/cc
10:30 pm the Kindex is 5,  Velocity: 452 km/sec Bz: -6.0 nT Density = 22.0 p/cc (still good)

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.
