Is it a ligthning? Is it a firework? No, it’s a meteor! It’s while checking the video recordings from his camera in Torres – RS, that Gabriel Zaparolli, a BRAMON (Brazilian Meteor Observing Network) member, got the intuition that the flash he recorded on April 12, 06h 20min UT was a bright meteor…

Good bet! By checking the other cameras of the Brazilian video network, its members were able to detect the fireball path on 2 recordings, whereas the light flash was recorded on 5 of them, and even on the images of GOES-16 satellite.

By analyzing the recordings, meteoroid is expected to weight between 6 and 16 kg before it entered the atmosphere at a 34 km/s entry speed, over the Atlantic Ocean. It did apparently not survive this dramatic atmospheric entry, as it disappeared at a 37 km altitude above sea level, 145 km South of Rio Grande do Sul.
