Super meteor illuminates the air of Italy, rain of observations also in Rome. «A roar»

The period for shooting stars is the right one, but the trace of the one that was observed just before 21 is really strong emotions, even in these nights dedicated to the flock of Perseids: from Liguria to the Marche to the coast of Lazio & # 39; Fireball & # 39; marked the vault of the sky that was cleaned in the afternoon by the storm. Among those who have reported the phenomenon is also the Roman group Facebook "There is life on Colombo", the site inmeteo.it and the scientific journalist of RaiNews, Andrea Bettini. And there are also people who have heard a roar after the wake that had a very strong magnitude: from -3 to -5.

Grossa #meteora observed at about 8.55 pm in the air of much of the center-north #bolide

– Andrea Bettini (@andreabettini) 18 August 2018 [Bolide] ] è is the empirical name of the meteoroids (up to several tens of kilograms) entering the atmosphere of a planet at a speed that can reach 72 km per second: these small fragments of cosmic rocks are overheated by friction with the gas molecules atmospheric and partly evaporate or completely. The gases along the meteoroid path are ionised, emitting light of different colors (depending on the temperature reached and the chemical composition). The light trail that is visible in the sky is called meteor, or shooting star

in Italy there is a network for monitoring meteors that thanks to numerous stations makes it possible to reconstruct the route by crossing the observations.
