Aurora Occurring NOW! (20 August)
Aurora are visible NOW!
They have been seen in Lymington and Abels Bay, Tasmania. The activity may be like yesterday dying off only to pick up again. Current Solar wind parameters are not great Velocity: 767 km/sec Bz: 0.0 nT Density = 9.0 p/cc but glows still being reported with a Kindex in Hobart of 3. The SWS has issued an aurora watch for tonight due to ongoing activity. The Moon is waning, and is rising around 5:30 am in the early morning so will hardly interfere with morning aurora. Be patient, as the activity may rise and fall as the magnetic polarity of the wind may fluctuate significantly.
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, as well as bright proton arcs and "picket fences".
