Twitter was flooded with videos claiming to show the bizarre phenomenon in Mage, outside of Rio de Janeiro.
In one of the clips, a gyrating blue sphere is seen floating above the city. The video was tweeted at Elon Musk.
“There are reports that something fell over there in a lake … But it doesn’t seem to be a satellite,” Andre Di Mauro wrote.
Another video shows a group of five illuminated spheres in the night sky – a bizarre visual phenomenon which “many people saw,” according to one Brazilian who shared the clip. Others posted footage of a floating red orb, as well as strange flashing lights in the horizon.
According to reports, the terms “Mage” and “Pau Grande” – the district of the city where the alleged incident took place – trended on Brazilian social media on Wednesday.
Despite the chatter online, authorities claim they are unaware of any unusual incidents. The city issued a notice stating that it had no information on the matter, local media reported, adding that the Brazilian Air Force claims it received no calls regarding the unusual objects.
