On Friday evening a lot of Australians could see a spectacular and very colourful fireball over their south-east coast. The event happened on 5 July 2019 at 20:50 AEST (10:50 UTC). There are reports from all over New South Wales and Victoria. The colour suggests that the entering object has a large amount of iron and nickel.
Following The Canberra Times Dr Brad Tucker, astrophysicist at the Australian National University, estimated the entering object to have a size of about 1 m and a mass of hundreds of kilograms.
The following stunning image of the fireball over Lake Lonsdale in Victoria was captured by Andrew M Beale according to the tweet of Vic Storm Chasers.

Even if there were reports of a sonic boom, a preliminary analysis of the infrasound data of the International Monitoring System of the CTBTO did not show any significant signature of the fireball in the data. The closest station had an estimated distance to the fireball of more than 750 km.
