Aurora Australis: Aussie stargazers may get another glimpse of the spectacular light show tonight

Stargazers could be set for another dazzling light show after the night sky was lit up by Aurora Australis across the nation for a second consecutive night.

Aussies from as far as Mackay in the north to Tasmania in the south were treated to colourful green, pink and purple hues as a huge geomagnetic storm struck Earth.

Images of the stunning light display flooded social media as millions had their backyards lit up in the middle of the night on Saturday. 

However, disappointed Sydneysiders and Canberrans missed out on Saturday night with the light show blanketed in dark clouds and rain.

There’s hope those who missed out will get a final chance on Sunday night with 10pm-2am set to be the best viewing time.

The Bureau of Meteorology (BOM) has predicted the geomagnetic storm, while not as strong, could bring the light show back on Sunday night. 

Australian Space Weather Forecasting Centre manager Kate Brand said Saturday night’s light show was unusual.

‘Aurora is usually seen near the North Pole or the South Pole but at the moment the sun has been really active, there’s been quite a lot of space weather activity,’ Dr Brand told AAP.

She added that Aurora Australis could be seen on Sunday night but ‘perhaps not as far north’.

‘We are expecting that they may be visible in the southern parts of Australia,’ Dr Brand said.

‘So in Tasmania, South Australia, Southern Victoria and perhaps southern NSW.’

The storm over Australia reached G4 geomagnetic storm level, considered severe, which hasn’t been seen since 2004.

Dr Brand said geomagnetic storms are not dangerous to humans but can impact technology an communication infrastructure.

‘For example, satellites could be impacted which are used for position navigation and timing, it can cause increased currents in the power network and things like high frequency, or HF communication, can also be impacted,’ she said.

BOM decreased the current geomagnetic storm level down to G3 at 1pm on Sunday, considered strong.

‘Aurora sightings are possible at low-latitude locations across Australia tonight including Tasmania and areas of southern NSW and Victoria,’ the bureau said.
