Experts from Curtin University's Desert Fireball Network (DFN) believe last night's fireball and sonic boom was caused by small piece of asteroid, less than one metre wide, hitting the atmosphere and breaking up over the Earth.
Dr Hadrien Devillepoix said the fireball — reported at 8:09pm local time, east of the Perth metropolitan area — would have been visible up to 500 kilometres from Perth in Geraldton, Kalgoorlie, and Albany.
The exact location cannot be determined because remnant cloud hindered DFN's cameras from being able to triangulate the asteroid.
"Not many people actually saw the fireball directly," Dr Devillepoix said.
"We got it on one camera — all the way down in Katanning in the Wheatbelt."
