New Zealand’s night sky lit up with streams of pink and green, treating viewers to a spectacle of the Aurora Australis.
The lights, visible to the naked eye, were seen across the southern island, all the way up north to Wellington and Hawke’s Bay.
Kiwis rushed to social media to share the sights, which was caused by a significant G4 level geomagnetic storm.
One photographer, Natalie Crowther, has been chasing for a shot of the phenomenon for 10 years. Last night, she was finally able to photograph the lights over Lake Ellesmere.
After the skies darkened, Crowther said she began seeing “weird fog curtains” and vertical pink beams of light that was constantly changing.
“The first time I saw [an aurora] was when I was 18 years old. Now everyone is out taking photos of it,” she said. “People were on the hill trying to capture it—but not knowing what direction to look.”
Across the ditch, the lights were also visible to early risers in Southern Victoria in a rare display, which are usually only seen in Australia’s southernmost state of Tasmania.
Abby Burleigh, a dairy farmer in Nullawarre, said it took her by surprise.
Senior meteorologist at the Australian Bureau of Meteorology (BOM), Dean Narramore, told ABC that people may be in luck for a second viewing of the aurora tonight.
Increasing Number of Aurora Sights
Both the Aurora Australis (Southern Lights) and the Aurora Borealis (Northern Lights) have become increasingly active.The BOM explains that Auroras are the result of the collision of charged particles from the Earth’s magnetosphere and atoms in the upper atmosphere, which come from sun activity.
“These charged particles are accelerated down magnetic field lines towards the Earth’s atmosphere in regions around the poles known as ‘auroral ovals,’” the bureau said.
“The different colours visible in auroras depend on the atoms that participate in the collisions and the interactions that occur with the charged particles.”
The sun goes through a magnetic cycle every 11 years, and it is currently approaching the height of its current cycle, known as the solar maximum, when there will be an increase in solar activity.
With increased solar activity, there is more solar flare energy which also means more auroras.
The most recent solar storm has caused skies to change colour across not only New Zealand and Australia, but also in the UK, Europe, and the United States.
