8th May 06:25 UT ( 03:25 BRT) prograde SW to NE bolide over Brazil
Update Eucrite recovered
A great flash followed by a strong explosive sound.
Videos registered in 8 cameras in 7 cities in Minas Gerais, São Paulo and Paraná.
According to preliminary analysis, the object followed a prograde trajectory from southwest to northeast, starting its luminous phase at about 64 km height, between Araxá and Uberaba. It shone bright headed towards the northeast at a speed of 15.36 km/s until it exploded at a height of 30 Km, close to the Municipality of Tiros, in Minas Gerais.
Analysis is under revision by Bramon and efforts are on to determine the object’s initial mass.The current data suggests that some fragments of this meteoroid possibly survived the atmospheric passage and reached the ground.

End of bolide trajectory recorded by NTV
Despite the heavy clouds, the bolide was also recorded by SONEAR’s allsky camera:
Update 4th November 2020
Mr. Titota, a farmer recovers a 400 gm chunk of Vesta on September 18, 2020 from this fall.
The rock had been found very close to the end of the trajectory calculated by BRAMON.
According to the analyzes already carried out at UFRJ, Meteorito Tiros is an eucrite type condition. Eucrites are rocky meteorites from deep regions of the Asteroid Vesta crust. It is believed that a large part of the Eucrites were launched into space by a gigantic impact at the south pole of Vesta, also responsible for the creation of the Rheasilvia crater, proportionally one of the largest in the Solar System. The eucrite is the most common type of achondrite, that is, rocks that have undergone a process of fusion and recrystallization, and no longer have chondrules. They are very similar to basalts and terrestrial lavas, but, while terrestrial ones are dark, eucrites are much clearer, as they are rich in calcium. Another characteristic of eucrites is the glassy glow of the melting crust, something quite striking in Meteorite Shots.

Of 22 documented finds from Minas Gerais this will be the second Eucrite. The first was from an observed fall on 30th June 1957
