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.

SUBJ: IPS GEOMAGNETIC DISTURBANCE WARNING 15/32
ISSUED AT 0147UT/14 AUGUST 2015
BY THE AUSTRALIAN SPACE FORECAST CENTRE.
A partial halo CME observed in LASCO C2 imagery at 14:48 UT on
12 August associated with the long duration B7.0 flare and the
filament eruption from the southwest quadrant is expected to
cause a glancing blow early in the UT day, 16 August. Expect
periods of Unsettled to Active levels in Australian region with
chance of isolated periods of minor storms at higher latitudes.
INCREASED GEOMAGNETIC ACTIVITY EXPECTED
DUE TO CORONAL MASS EJECTION
FOR 16 AUGUST 2015
