This year, the Southern Lights have been unusually active, as the Sun undergoes a period of intense activity, which occurs in 11-year cycles.
今年，南极光异常活跃，因为太阳经历了一段以 11 年为周期的强烈活动期。

At Karioitahi Beach, south of Auckland, Simon Jarman (@sjarmanphoto) said it was a “decent show” on Friday, posting on NZ Dark Skies the aurora “went off” around 9pm, “died down then came back around 11.15”. His shot was taken facing west.
在奥克兰南部的 Karioitahi 海滩，Simon Jarman （@sjarmanphoto） 表示，周五的表演“不错”，他在 NZ Dark Skies 上发布极光在晚上 9 点左右“熄灭”，“消退然后在 11 点 15 分左右回来”。他的镜头是面向西方拍摄的。

But an astronomer says Friday was the peak of the aurora australis’ return to New Zealand.

Stardome astronomer Rob Davison says another display is unlikely as the geomagentic storm has ended..
Stardome天文学家Rob Davison表示，由于地热风暴已经结束，不太可能再次出现。

The aurora displays are related to activity from the Sun.
极光显示与来自太阳的活动有关。

Usually particles from solar flares bounce off the Earth’s magnetic field, but when there is a severe eruption, they can penetrate the ionosphere and interact with gases around the magnetic poles – causing the ribbons of colour.
通常，太阳耀斑中的粒子会从地球磁场中反弹，但当发生严重喷发时，它们可以穿透电离层并与磁极周围的气体相互作用——从而产生色带。

Auroras are usually confined to certain latitudes in the north and south, which makes them relatively rare to observe for most of the population.
极光通常局限于北部和南部的某些纬度地区，这使得它们对于大多数人群来说相对罕见。

The pinks, purples and greens that are often associated with aurora are the particles interacting with different gasses. Simply put, oxygen – which emits greenish-yellow or red light – and nitrogen – which emits blue light – in the upper atmosphere release specific colours when bombarded by solar radiation.
通常与极光相关的粉红色、紫色和绿色是与不同气体相互作用的粒子。简而言之，高层大气中的氧气（发出黄绿或红光）和氮（发出蓝光）在受到太阳辐射轰击时会释放出特定的颜色。

Atoms, molecules and ions in the atmosphere are excited by the electrically charged particles and, in turn, release photons – which is the light we see.
大气中的原子、分子和离子被带电粒子激发，进而释放光子——这就是我们看到的光。
