Aurora Alert! Geomagnetic Disturbance Warning (2-3 November)
The Australian IPS has issued a Geomagnetic Disturbance Warning for possible
major storms and the NOAA site has a predicted G3 storm from a fast moving solar
wind stream from a coronal hole that produced G3 storms in early October 7-8.
The arrival of the solar wind stream will be anywhere between the morning of the
2nd of the morning of the 3rd Australian time (it might even arrive early on the
evening of the 1st). Given the bounty of aurora from the last visitation of this
hole, there is a strong possibility we will get unaided eye visible aurora in
both Tasmania and the Southern mainland.
Evening skies are clear of the Moon, and the waning Moon will interfere on the mornings of 2nd and 3rd, but not as much as the Full moon.
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.
If you are up early on the morning of the 2nd and 3rd, you can see a beautiful line-up of bright planets - Jupiter, Venus and Mars with Venus and Mars are at their closest on the 3rd. After this the waning Moon joins the line-up, on on Saturday 7 Nov an Sunday 8 Nov the crescent Moon is close to Jupiter and Venus respectively, indeed on the 8th you can use the crescent Moon to see Venus in the daylight. More details here. http://astroblogger.blogspot.com.au/2015/10/the-planet-dance-continues-venus-and.html

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