On Sunday night, Australians were captivated by a stunning natural light show, as vivid pink and green auroras lit up the clear winter skies.
The aurora australis, normally reserved for southern latitudes, was visible as far north as Tamworth in New South Wales due to favorable weather and a strong geomagnetic storm.
Rare Northern Display
Clear skies over Ben Lomond in Tasmania provided ideal viewing conditions. According to astronomer Fred Watson, seeing the aurora this far north is rare and was made possible by a particularly powerful solar storm.
Auroras occur during geomagnetic storms, which are triggered when the Sun ejects charged particles into space. These particles interact with atmospheric gases—oxygen and nitrogen—to produce the glowing lights.
“The stronger the storm, the further from the poles the aurora can be seen,” Dr. Watson explained.
Sightings Across the Country
In Merimbula, vibrant colors were visible reflecting off the water, while in East Devonport, Tasmania, Cressida Toorenburg described a magical moment as the clouds cleared.
“We waited for the sky to open up, and then suddenly — Lady Aurora appeared,” she said. “It was breathtaking, visible to the naked eye, but even more vivid through my phone’s camera.”
She noted that in her seven years living there, she’d never witnessed such a brilliant display.
Extra Celestial Activity
In addition to the auroras, a meteor lit up the skies over Sydney at around 6 p.m. on Sunday.
Brad Tucker, an astrophysicist at the Australian National University, attributed the brilliant auroras to a major solar storm. “The stronger the solar storm, the more intense the aurora on Earth,” he said.
Tucker recommended skywatchers head outside just after sunset on Monday for another possible viewing opportunity.
More Activity Expected
According to the Australian Space Weather Forecasting Centre (ASWFC), heightened geomagnetic activity is forecast to continue until June 3. Monday’s forecast has a G-scale of 4 out of 5, signaling a strong likelihood of visible auroras.
The ASWFC, part of the Bureau of Meteorology, offers geomagnetic storm alerts via email, which can be accessed by signing up through their website.
Looking Ahead
Although the last two years have featured some impressive auroras, Dr. Tucker cautioned that sightings may become less frequent as solar activity declines.
“We might get one or two more good storms this year,” he said. “But by 2026 and definitely into 2027, solar activity will drop, and auroras like this will be much rarer—you might need to head to the Arctic Circle to see them.”
