On September 20 evening, at 10h 31min UT (20:31 AEST), a very bright fireball and related sonic boum were observed, heared and video recorded over Northern Tasmania, Australia. The International Meteor Organization did not receive a lot of reports, althought the meteor event was dramatic, according to videos.
Did you see the sky light up in #Tasmania on Friday night? One of our five infrasound arrays detected a small fireball event ~100 km NW of #Launceston at 8:36 pm AEST on 20/09/19. We operate these arrays to monitor for nuclear weapons tests as part of the #CTBTO. pic.twitter.com/9cpFKaZpOx
