From the MetBul:
History: (A. L. R. Moutinho, D. Rios, M. Cardoso Rocha, W. Carvalho) A fireball appeared over the southeastern region of Pará state, Brazil, on June 29, 2017, around 10:35 local time (UTC-3). It was traveling in an apparent NE to SW direction. Loud detonations were heard in towns including Marabá, Eldorado dos Carajás and Paraopebas. People from these towns thought it could have been an airplane crash.
In the the village of Serra Pelada (a famous gold-mining location), some students and a watchman, Mr. Manuel da Silva, of Rita Lima de Souza school heard a series of four to six detonations and a few mins later witnessed a rock falling on a roadside near the school. A smoke trail was observed and also some dust caused by the impact. The rock was broken by the impact, collected and shared among local people just after the fall.
Another 5.4 kg piece was witnessed to fall few meters from an electrician while working. This piece was sold to an anonymous buyer. A geologist from Serra Pelada, Marcilio Cardoso Rocha, was contacted, and he made preliminary analysis and sent a sample to MNRJ for study and classification.
