Astronomers describe mysterious fireballs that lit up Melbourne's sky as 'unusual'
ABCExperts say back-to-back sightings of multiple fireballs detected across Victoria overnight were purely coincidental. Monash University professor and member of the network Andy Tomkins said the first sighting came in just before 6:30pm, followed by another about 9pm and two more just after 4am. "That's not uncommon with large fireballs, because they burn up in the upper atmosphere quite high up in the sky," Professor Tomkins said. 'Bit of a fluke', expert says Although the meteors were highly visible, they were not large enough to hit the ground as a meteorite, astronomer at Swinburne University of Technology Allan Duffy said. quite unusual to have two highly visible fireballs in the same location so close over the same space, so close in time," he said.
