Southern Sky Turns Electric: The Aurora Australis Boom of 2025 May Soon Fade Forever
Aurora australis stuns skywatchers across Australia, but solar storms driving these light shows won’t last. Here’s what to expect next.
- Biggest aurora in 20 years: Gannon Storm (May 2024)
- Solar cycle length: 11 years (current peak began October 2024)
- G4 and G5 storms: Highest levels of geomagnetic activity in decades
- Aurora sightings: As far north as Tamworth, NSW
Brace yourself — the skies of Australia have delivered some of the most jaw-dropping aurora australis displays in living memory. But these psychedelic lights aren’t here forever. Experts warn the electrifying flares and ribbons of color could vanish within a couple of years, as the Sun’s stormy cycle calms down.
From Tasmania to South Australia and beyond, photos taken this week show whole horizons set ablaze by the “southern lights.” Vivid greens, fiery reds, and ghostly purples have painted clouds, sent stargazers racing outdoors, and clogged social feeds with dazzling time lapses.
Q: What Exactly Is the Aurora Australis?
The aurora australis is the Southern Hemisphere’s answer to the famous northern lights, or aurora borealis. The name “australis” comes from Latin, meaning “southern.” During an aurora event, the night sky erupts into glowing curtains of color — a phenomenon caused by geomagnetic storms as charged particles from the Sun smash into Earth’s magnetic field.
It’s nature’s own celestial ballet, lighting up the skies from the tip of Tasmania to even the southern reaches of New South Wales.
Why Are Auroras So Intense Right Now?
This year, the Sun is raging at the peak of its 11-year solar cycle, called the solar maximum. According to the NASA, the current uptick began in 2019 and hit its stride in October 2024. These wild solar storms — known as coronal mass ejections — unleash shockwaves of solar material into space, bombarding Earth and triggering G4 and G5 geomagnetic storms, the most powerful on the scale.
Not since the Gannon Storm of May 2024 — the biggest in two decades — has the world seen auroras of this magnitude. The resulting “space weather” has made aurora hunting possible in regions that haven’t glimpsed them for generations.
Catch-up: Similar phenomena illuminate the Arctic Circle for the northern hemisphere’s aurora chasers too. However, Aussies are experiencing a truly rare run.
Will Auroras Vanish After 2025?
Don’t expect these light shows to last. Experts at the Bureau of Meteorology and Australian National University say we could revert to “quiet” years anytime between 2026 and 2027. As the solar maximum fades, so too will widespread southern light displays.
It gets even trickier: No two solar cycles are alike. Some produce wild, frequent displays; others stay relatively calm. But one thing’s certain — when this peak passes, future auroras will be far less common and likely visible only from the southernmost edges of Australia, or the polar circles.
Q: Can I Still Catch Auroras Later This Decade?
Yes, but with caveats. Even in quieter solar years, significant space weather could still create brief aurora events. The next true boom, though, won’t happen again until the 2030s, so hardcore chasers may need to travel to Antarctica or the Arctic Circle for the next big show.
How To See the Next Aurora Before It Vanishes
- Sign up for geomagnetic storm alerts from the ASWFC (Bureau of Meteorology).
- Monitor active space weather forecasts via NOAA and NASA.
- Head as far south as possible for the best chance — Tasmania remains hotspot #1.
- Watch clear, dark skies away from city lights on forecasted high-activity nights.

- Know the cycle: Solar maximum won’t return until the 2030s
- Go south: For future auroras, you’ll need to be closer to the pole
- Capture the moment: Use your best camera and aim for clear, open horizons
This could be your last, best chance to witness the southern lights from your backyard. Don’t wait — gear up, look up, and make your own memories before the auroras retreat for another decade!
