Aurora Alert 19-20 December

A geomagnetic alert and aurora watch has been issued by the Australian IPS, the activity is due to a glancing blow from a coronal mass ejection. The activity is likley to peak late in the evening of the 19th to the early morning of the 20th, possibly lasting to the night of the 20th.

If aurora occur, this may be visible in Tasmania, New Zealand, and possibly Southern Vic, WA and Southern South Australia. However, geomagnetic storms are fickle, and the storm may arrive in daylight or may fizzle out entirely .. or might just be spectacular.

 As always look to the south for shifting red/green glows, recently beams have been reported too. As usual, dark sky sites will have the best chance of seeing anything, and always allow around 5 minutes for your eyes to become dark adapted.

The all sky aurora camera in Southern Tasmania at Cressy may be of help in monitoring for aurora http://www.ips.gov.au/Geophysical/4/2
