Aurora Happening NOW! (25 October 9:08pm AEDST)
Unaided eye aurora are being reported from multiple Tasmanian sites including
Hobart, Cygnet, Seven Mile, Howrah and Margate NOW. The indexes are good although Kindex is rubbish (Velocity: 502 km/sec
Bz: -14.0 nT
Density = 8.0 p/cc but Kindex is still 3) but people are
reporting aurora including beams! It is expected that the magnetic field
polarity will swing back and forth during the night, so there may be out busts
of aurora then it dying down before flaring up again. Weather and clouds are a
bit ordinary too.
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, as well as bright proton arcs and "picket fences".
Here is the near-real time satellite view of the clouds http://satview.bom.gov.au/
Cloud cover predictions can be found at SkippySky.
