August fireballs over Australia, Denmark, and Antarctica

Want to combine your vacation with some meteor(ite) science? Right now, you have some exciting options: Denmark, Australia, or—if you’re feeling more adventurous—Antarctica and the Vostok Station!
In recent days, bright fireballs have been observed over these regions, possibly linked to meteorite falls.
So… which flight will you choose?

Australia: two fireballs in a row near Melbourne on August 10th

On August 10th, 2025, two very bright fireballs enlighted the sky of Melbourne region (Victoria, Australia) in less than 80 minutes timespan! The first one, which occured at 09h 34min UT (19h 34min AEST*, event #4726-2025) lasted several seconds, and was the most observed and video recorded. Some people witnessing the event (Figure 1) also reported hearing sonic booms shortly after they spotted the bright meteor. Such sounds indicates meteorites may have reached the ground, as final altitude estimation of the meteor goes down to 9 km! From calculations by the Desert Fireball Network (DFN) and the Global Meteor Network (GMN), strewn field would be located North-East of Maryborough (Victoria, Australia), 140 km North-East of Melbourne.

The second fireball was less widely documented and occured the following hour, around 10h 48min UT (20h 48min AEST*, event #4727-2025) above central Victoria (again). From automatic calculations issued from visual observations, this meteor seemed to go offshore, and protential associated meteorites must have landed on the seafloor of Bass Strait (Figure 2).

Denmark: sonic booms associated to fireball sightings on August 5th evening

It was 19h 17min UT (21h 17min CEST**) in Denmark, and the sky was not yet fully dark, on August 5th, 2025, when a very bright fireball crossed the sky and was reported by more than 80 persons (event #4628-2025, Figure 3). As the Sun was not far below the horizon, the vapor trail was visible and deformed due to the high altitude winds, which was widely photographed by witnesses (Figure 4). Some people also reported having heard sonic booms, which indicates the fireball must have gone down into the lowest part of the atmosphere, leading the possibility that some meteorites may have reached the ground…

Antarctic: a dramatic fireball over a desert area on August 13th

Most fireballs appaears unobserved, as most of them appear above deserts, oceans, and nearly no-populated areas. But sometimes, a meteor appear above a very-low-populated area, and it’s observed! That is what happened on August 13th, around 11h UT (16h VOST***) above Vostok station, in… central Antarctica (lat. ~ 78° 27′ 51″ S ; lon. ~ 106° 50° 14″ E)! Just a few humans, the scientists of the  Arctic and Antarctic Scientific Research Institute (AARI) were able to observe the event and photograph the residual vapor trail enlighted by the Sun (Figures 5.a- to f-), which was not very low below the horizon, during more than half an hour.
