Phillip Island had front row seats to an incredible natural phenomenon on the weekend.

So just why were our skies on Saturday night so spectacular? Kate Brand, Manager of the Australian Space Weather Forecasting Centre at the Bureau of Meteorology said the Aurora was the result of a very large "geo-magnetic storm", which registered between four and five on the planetary scale (five being the most extreme).

Kate described the sun as being "really active", with a lot of space weather activity.

"There were a number of Coronal mass ejections (CMEs) - essentially clouds of charged particles - and when these head towards earth they can interact with our magnetic field and our atmosphere, which can result in Auroras being visible further north or south of the poles than normal."

The stunning light display was captured by photographers across the island.
