Geomagnetic alert (6-7 January)

The Australian Space Weather Service (SWS ) has now  issued a Geomagnetic Alert for possible geomagnetic storms on 6-7 January UT from a coronal hole. A G1 storm has been predicted, although it may occur in the late afternoon during daylight. There is a possibility we will get unaided eye visible aurora in Tasmania and less likely for the Southern mainland. Evening skies are Moon free, morning skies have a crescent Moon near Venus and Saturn.

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/

The all sky aurora camera in Northern Tasmania at Cressy may be helpful.

Coronal hole effects are likely to result in periods of active
geomagnetic conditions in the Australian region, with minor storm
levels at higher latitudes.

INCREASED GEOMAGNETIC ACTIVITY EXPECTED
DUE TO CORONAL HOLE HIGH SPEED WIND STREAM
FROM 06-07 JANUARY 2016
