The page on the Facebook social network ‘Meteo Trás os Montes — Portugal’ released this Tuesday night reports of the fireball seen mainly in the north of Portugal, but in other parts of the country.

The entry of a meteorite into the Earth’s atmosphere results in that phenomenon.

“By the behavior of the rock, it is most likely that it came from an asteroid and not a comet”, he also told Lusa.
According to the first information, still without confirmation, the rock will have flown over the north of Portugal or perhaps the Atlantic along the coast of Portugal and Galicia, he stressed.
