Aurora chasers across the country are buzzing as the beautiful beams of light known as Aurora Australis (Southern Lights) start to appear this evening.

Members of the Aurora Australis (NZ) Facebook page have started posting their photos as the evening sky turns a purple and pink hue.

The lights have been spotted all over the country, from Bay of Plenty, Hawkes Bay and Wellington, to all the way down south in Cromwell, Twizel, Queenstown and many other places.

Hauraki Gulf weather reported a significant G4 level geomagnetic storm had been under way today.

 “Currently fluctuating at levels that are like the storm on March 24, so there is a chance of viewing the Aurora Australis from the upper North Island tonight,” Hauraki Gulf Weather tweeted, referencing another storm that caused the display of lights last month.

“Over the Tasman from West Coast is best.”

Both the Aurora Australis and Aurora Borealis have been particularly active following recent solar storms, RNZ reported last month.

Astronomer and Otago Museum director Dr Ian Griffin told the Otago Daily Times last month during another stunning display the solar storms were caused by magnetically driven explosions on the sun, that fire material at high speed away from the sun.

 “That sounds terribly complicated, but what it is is basically the sun fires material occasionally towards Earth.

“And we’ve had two of those ejections in the last two days.”

Both were travelling between the sun and the Earth at about 800km per second.

When that material hits the Earth’s magnetic field it starts to spiral around it, he said.

When energetically charged particles travelling along the Earth’s magnetic field lines strike the upper atmosphere, the Southern (and Northern) Lights can be observed around the magnetic poles.

These powerful electrons produce light when they strike atmospheric gases.

The phenomenon is known as the Aurora Borealis in the northern hemisphere and as Aurora Australis down under.

Budding astrophotographers were abuzz on social media, sharing tips on how to capture the display of lights and questioning how far up the country it could be seen.

MetService is reporting clear skies overnight for much of the South Island where the lights are expected to be the most visible.
