Canberra skies may display the Aurora Australis tonight due to a severe geomagnetic storm. An Australian National University professor indicated visibility could be as bright as November's event. The storm, caused by a solar coronal mass ejection, is expected to persist into the evening. Such storms can potentially disrupt critical infrastructure like power grids and satellite services.

Australian National University professor Dr Brad Tucker said the Aurora Australis would be visible in Canberra on Tuesday, January 20, based on the strength of its current levels.
"If [the aurora] lasts into the evening, so if it stays the same strength as of right now, in terms of the indices and strength they're measuring ... we would see it as bright as what we saw back in November in Canberra," he said.
"The question is, will it last for another seven to eight hours. That's probably a hard ask because usually the storms last anywhere between one to two hours.
"This has arrived quite quickly, so it just depends on how much energy is with this storm and whether we get more waves of it arriving later."
The Australia Space Weather Forecasting Centre issued an aurora alert on Tuesday morning, January 20 for a severe geomagnetic storm.
"Aurora may be observed during local night time hours in good observing conditions at regions as far equatorward as middle latitudes."
Middle latitudes lie around Tasmania.

A Bureau of Meteorology spokesperson said the storm conditions were currently ongoing and expected to continue until later this evening.
"This event is a result of a coronal mass ejection that occurred on the Sun on Monday 19 January 2026 at approximately 5.12am AEDT," the spokesperson.
Geomagnetic storms of the current intensity could potentially disrupt, critical infrastructure such as power grids, satellite services, and services that use high-frequency radio communication, the spokesperson said.
The Australia Space Weather Forecasting Centre's website measures the Kp index on a scale of one to nine, with nine emblazoned in red indicating a major geomagnetic storm, Dr Tucker said.

"Because it's going to be in the southern skies, you want to go south of the city lights ... get to a dark spot, so it could be like a nature strip or a nearby oval somewhere with less immediate lights that will maximise what you see.
