Tasmania is well favoured to see auroral displays due to its southerly latitude and proximity to the auroral oval.
Aurora are generally seen in the southern sky, although under stormy conditions the oval may extend over Tasmania, and even be observed in the northern sky.
The City of Hobart is especially favoured to see the aurora due to our latitude of 42.8 deg. South, and to the invariant pole being pushed in our direction each night.

At our latitude, the aurora may have an angular extent along the horizon of from 50 to 100 degrees and reaches no further northwards than the zenith. Displays tend to be centred on the magnetic pole, which is about 19 deg. to the west of the geographic pole. On rare occasions the aurora may cover the entire sky - It is a sight that lives in the memory forever.
