Description: Southern Lights Issue date: 26 August 2014 The Southern Lights (Aurora Australis) are the counterpart of the Northern Lights (Aurora Borealis). Auroras most commonly occur above a band of high latitudes in each hemisphere, known as the auroral zones. Each auroral zone is centred on the Earth’s magnetic poles, and lies between latitudes of approximately 50˚ and 60˚. The Southern Lights are less commonly seen than their northern counterpart, as there are comparatively few populated regions under the auroral zone of the Southern Hemisphere The two main discernible forms of aurora are a diffuse glow, which generally appears towards the poleward horizon, and discrete forms such as arcs and curtains that stretch from east to west, as well as rays that may run upward from the horizon. These forms are shaped by the Earth’s magnetic field. When the aurora is sufficiently bright, specific colours may be seen, most commonly green, red and violet. These colours depend on energy of the incoming solar particles, and the type of atmospheric gases they interact with. The Southern Lights are best seen from the islands of the Southern Ocean and Antarctica. In Australia, they are occasionally observed in the southern skies of Tasmania, and sometimes from southern locales on the mainland.
