Meteoro lights up the skies in Mato Grosso and Mato Grosso do Sul; Look

Passage lasted just over three seconds and was recorded by residents

A meteor lit up the city skies in Mato Grosso (MT) and Mato Grosso do Sul (MS) in the late afternoon of Thursday (9).


The phenomenon was spotted by the businessman Anderson Dal Lago near the airfield of Santa Maria (MS), around 6 pm, in the time of Braslia. The images were made available on the Campo Grande News website. Although it was fast, it is possible to see a “fireball” with a very bright glow at the bottom of the image. Some residents said they heard a noise at the time of the meteor’s passing.

Visualization of these phenomena in the southern hemisphere begins to be more common from the second half of the year, and a large meteor shower is expected on the next 29th.

The video was sent to Giovanni Rescigno, a member of Exoss MS, a program that studies images of phenomena like this. Rescigno assessed the content and told the site that the passage of the meteor lasted 3.5 seconds, with the object disintegrating in the atmosphere afterwards.

According to Rescigno, the intensity of the phenomenon’s brightness (magnitude) reached -11. For comparison, the magnitude of the Moon, when at its maximum brightness, reaches -12.9. The evaluation of Exoss MS, however, was inconclusive as to the size and speed of the meteor.

According to data from the National Institute for Space Research (Inpe), this phenomenon occurs when a particle or grain of dust enters the Earth’s atmosphere. On average, this waste reaches a speed between 100 km / h and 200 km / h. Friction with gases from the upper atmosphere causes these particles to reach high temperatures and enter combustion, causing the strong glow we see.
