Aurora australis to be visible for large parts of Australia in rare event

The aurora australis will be on display for mid to southern parts of Australia tonight thanks to a severe geomagnetic storm impacting Earth.

The Bureau of Meteorology's Space Weather Forecasting Centre has issued an "aurora watch" for the coming hours with visibility possible.

Swinburne Space Technology and Industry Institute Dr Rebecca Allen said people as far east as Sydney and as far west as Perth will be able to witness the phenomenon from sunset about 8pm AEST.

"You would potentially have a bit better of a chance seeing it further on the east coast versus the west coast, because of just potentially when the activity is peaking," she said.

Allen said the best way to see the auroras would be at places with a clear view of the horizon, like a beach or bay.

"It's going to be a bit trickier for us in the urban environments," she said. 

Auroras can be observed from as far as 1000km away if it is bright and the conditions are favourable. 

It is quite rare for them to be visible over large parts of Australia.

Auroras are caused by particles from a geomagnetic storm interacting with the Earth's magnetic field, which Allen said creates "beautiful curtains of light".

Solar wind or flares typically spark these storms.

NASA has recorded a large solar flare in the past 24 hours. 

Allen said the sun is currently at its most active part of the 11-year solar cycle and is peaking.

"So that's why we're seeing so much aurora activity," she said.

Allen said there have been more reports of aurora activity than ever before, which has set a "new tone for what we expect" in the coming years.

"We haven't seen anything like this before," she said. 

"What's to say during the next solar cycle that there couldn't even be more of these flares?"

MP to launch High Court challenge against ‘unconstitutional’ social media ban

NSW MP John Ruddick has announced he will challenge the federal government's world-first social media ban in the High Court.

In a statement, the Libertarian MP said he would argue the new law coming into effect next month is unconstitutional as it violates the "implied constitutional freedom of political communication".

He will be filing with the court, via the Digital Freedom Project he leads, "imminently".

John Ruddick.

"The guts of the matter is that to have a social media account in Australia from 10 December you will need to prove to the social media platform you are over 16," he said.

"That's going to be a hassle for social media users and a huge administrative burden for the social media platforms.

"Lots of bright young kids who are curious about science or history or whatever learn so much from social media. Lots of people choose to have an anonymous social media account."

Ruddick has a limited number of sitting days to have his bid mentioned in the High Court ahead of when the rules come into effect.

Google is also reportedly preparing to launch a last-ditch legal challenge against YouTube's inclusion in the ban. 

Communications Minister Anika Wells declined to comment.

Children under 16 will be banned from Facebook, Instagram, Snapchat, TikTok, X, YouTube, Threads, Reddit and Kick, with social media platforms that fail to reasonably enforce the restriction to face a fine of up to $49.5 million from December 10.

Concerns have, however, been raised that the rules do not go far enough to include similar platforms like Discord and Roblox, and are easy for children to circumvent.

The eSafety Commission has said the list of platforms included in the ban is not "static", suggesting more could be added in the future.

Prime Minister Anthony Albanese has acknowledged his world-first ban is not perfect.

"We do argue, very strongly, though, that this is the government of Australia setting down what we expect to happen, including reminding social media companies that they have a social responsibility, and that they need to be conscious about their social licence, like other businesses," he told reporters on Monday.
