Scientists are closer to finding a meteorite that flashed over Western Australia's south more than two months ago, after narrowing the search area.
Dozens of people spotted the bright, white light speeding across the Perth and South West skies on March 9.
Professor Phil Bland, who leads Curtin University's Desert Fireball Network, said dashcam footage provided by eyewitnesses only provided a narrow range of angles that would indicate where the fireball came from and where it was going.
"We're still working on that one," Prof Bland told AAP.
"All the observations were from Perth.
"It's kind of like trying to see something in 3D and you can only see a couple of inches either side.
"What we've had to do is go back to all those sites where the videos were taken, make a 3D laser scan of the entire site, put that into a computer ... and then we move a kind of virtual camera through a 3D recreation of the site, working out every angle frame by frame.
"But we have narrowed it down, pretty well within 10km or so of where we might find it."
The DFN, which is part of the Fireballs in the Sky citizen science project, has taken spectacular images of incoming meteorites using a network of cameras in Australia's desert regions.
"Up until now, there's not really been a way that anyone's had for watching what's happening routinely in the southern hemisphere in terms of what's hitting the atmosphere, what's coming down to earth.
"It's kind of exciting to be able to do that.
"We've been working our arse off to build this thing and design all the software ... we've really just opened the book."
