Meteor Shower Adorns Southern Lights Over Tasmania.
A bright "fast-moving" light with a green trail across the sky Friday night has captured the imaginations of at least a few locals who are this morning trying to get to the bottom of what it is they saw - or think they saw.

Advertiser.com.au has received and read a smattering of reports about the strange light, which one expert says could have been a meteor or space junk re-entering the earth's atmosphere.

A Reddit user reported seeing "what I can only guess was a meteor" pass over Henley Beach.

"Saw it from the city, fast moving bright light, green trail, bright flash."

Another Reddit user responded that the same phenomenon was witnessed by "a lot of people" on the Eyre Peninsula.

Salisbury East man Bradley Cousins said he was driving home from work in Tanunda around midnight when he looked up at the moon because it "looked strange".

"I was halfway along the road when all of a sudden, this orange/red light appears suddenly in the sky and it quickly got bigger," Mr Cousins said.

"At first I thought it was a meteor or something because of how it was getting bigger and travelling so fast, as a reflex I put on my brakes.

"Then all of sudden it instantaneously goes bright green, gets smaller and completely disappears without evidence of it hitting the ground.

"I know this sounds crazy and I sound crazy but I can't explain it."

Paul Curnow, lecturer at the Adelaide Planetarium at the UniSA's Mawson Lakes campus didn't see the light for himself but says he woke to several reports confirming sightings on the Eyre Peninsula.

"People have seen a meteor or something over Port Lincoln and so it must be a fairly big and bright one that's come across," Mr Curnow said adding that they were "not unusual".

"What I don't know is whether it's a piece of returning space junk."

"It could be something like that but I mean there's a lot of rock that comes in from space and we call those meteors and if they make their way to the surface of the earth we call them meteorites."

Mr Curnow said it might be possible to work out exactly what occurred if people happened to record the light via a dashcam or security camera.

"That's where we're getting more and more footage of these things.

"That would give it some sort of direction."
