Aurora australis Tasmania tonight

Tasmania aurora at a glance

Tasmania is Australia's aurora capital by a considerable margin. Its magnetic latitude of 53-55°S is equivalent to southern Norway, putting it within routine reach of the auroral oval during moderate geomagnetic storms. Hobart needs Kp 5 - the lowest threshold of any Australian city. No part of mainland Australia comes close: Victoria and South Australia sit 2-4 Kp steps higher in their requirements.

Dark sky access is exceptional. South West National Park covers more than 600,000 hectares of roadless wilderness. Cockle Creek, at the end of the Huon Valley road, is the southernmost point reachable by car in Australia - it faces directly south across the Southern Ocean with no artificial light between the observer and Antarctica. Bruny Island south coast and South Arm Peninsula offer similar southern horizons within 30-40 km of Hobart.

The aurora season runs from April to September. June to August delivers the longest nights - around 14 hours of darkness at this latitude - and steady winter weather patterns. The west coast receives considerably more rainfall than the east; on nights with westerly cloud, the Tasman Peninsula and east coast often remain clear. When planning an observation window, check forecasts for both coasts.

The G5 geomagnetic storm of May 2024 - the strongest in two decades - produced aurora australis photographed across the entire state, from Hobart rooftops to Cradle Mountain and the central highlands. That event confirmed Tasmania's position as Australia's most reliable aurora destination during major solar activity, and demonstrated that even Kp 9 storm conditions are accessible from sites that otherwise see Kp 5.
