In the video the sky is illuminated by lightning and a greenish red hue, when suddenly a bright white orb shines in the centre of the dark sky and appears to burst into nothingness and fade away.

An outline of the orb can be seen in the sky for a few seconds before it completely disappears.

A spherical ball of light lit up the skies of the Australian Capital Territory before quickly disappearing into thin air. Social media users have suggested extraterrestrial activity while experts speculate ‘ball lightning’

Jakka Warren was convinced the formation was a ‘Class B UFO’ because of the ‘typical hyperdrive residue’ formation which allegedly occurred.

‘They wanna tell me it’s a ball of lightning, nice try fools,’ said Mr Warren.

A video, originally uploaded to Reddit, shows a doughnut shaped orb appearing above Canberra during a storm on Sunday night, faintly backlit with a red and green glow

Mr Tucker said: ‘If it was, they might visit somewhere more active than Canberra.’

‘Sometimes, if you get a really interesting occurrence, you create something called ball lightning’ said Mr Tucker.

The red and green glow was also suggested to be an aurora but Mr Tucker said although it holds the characteristics of an aurora ‘there was no activity from the sun’ which is needed, when trying to see an aurora in the sky.

Australian National University astronomer Brad Tucker didn’t think it was aliens but suggested it may be the equally mysterious ball lightning weather phenomenon, which is often seen across Australia

A ball of light about the size of a grapefruit, with the intensity of a 40W light bulb illuminates for about ten seconds and then disappears.

The strange weather spectacle has been seen by hundreds of people but remains a mystery to this day, reported The Conversation.

Daily Mail Australia has contacted UFO expert Bill Chalker for comment on the event.

Meanwhile this comes after a bright orange streak of light was seen flying over the Northern Territory in October.

The UFO slowly shoots through the sky and experts speculated it could have been space junk re-entering the Earth’s atmosphere or a high alтιтude military jet with its afterburner.
