A ~600 gram meteorite fell about 15 meters from a ranch hand in Varre-Sai, Rio de Janeiro State, Brazil on June 19, 2010. The images show the meteorite and how it was found (though it was picked up first, and then replaced for the TV camera). The person talking to the reporter is Prof. Marcelo Souza, Professor of Physics and Astronomy at the Universidade Estadual do Norte Fluminense, in Campos. The interview will be aired on Brazilian TV today.
Near Hit!
There is an interesting follow-up to the daylight meteor fireball in Brazil of June 19, 2010. At about 21.00 UT, a ranch hand (name withheld) saw the fireball and heard explosions, after which something fell about 15 meters away from him in a pasture. He walked over to the spot and picked up a 600 gram meteorite that had just fallen from the sky. He saw others fall at about the same time nearby but hasn't been able to find them yet. He commented that the air had a "strong smell of iron".
The meteorite appears to be an ordinary chondrite with both primary and secondary fusion crust. I expect several more meteorites to be found from this fall based upon eyewitness reports. The local university and others will be joining the hunt today and in the coming days; stay tuned-in for more.
Have information about this meteorite fall or others? Please email drtanuki@gmail.com

"The rock is 50cm long, 40cm wide and 24 cm tall and weighs 145 pounds, three times more than a normal stone. The meteorite is a Sideritis, considered unusual by the fact that only 5% of the fragments that are already registered class - this may be the fourth located in the state. Throughout the country are recorded 56 meteorites, only 21 of that type. But it was not possible to end the day of fall. "

English translation: Topics Astro from granite has been used in stone and the tomb of the ancient castle, the well-known rock on Earth is. The continental crust of the earth are in plenty, and I would say the typical rock. But in fact our solar system are not universally present. The formation of "water" is thought to be involved and required. Venus and Mars, the planet Earth as the asteroid is dry and has not been found so far. Therefore, it was accepted view that the planet Earth is a unique rock water. However, the discovery has been reported to reverse the accepted theory.

Agricultor encontra meteorito raro
20 de julho de 2009 | N° 16036 Alerta
Ao aplicar veneno na lavoura de milho de sua propriedade, na zona rural de Arvorezinha, no Vale do Taquari, o agricultor Danilo de Oliveira surpreendeu-se com o que encontrou pelo caminho, na quinta-feira.
Caída no terreno, uma pedra pequena e pesada chamou sua atenção porque nunca esteve ali. Geólogos da Universidade Federal do Rio Grande do Sul (UFRGS) estiveram no local para realizar testes científicos e confirmaram: o fragmento se trata de um raro meteorito.
A rocha tem 50cm de comprimento, 40cm de largura e 24cm de altura e pesa 145 quilos, três vezes a mais que uma pedra normal. O meteorito é do tipo Siderito, considerado raro pelo fato de que apenas 5% dos fragmentos já registrados são dessa classe – esse pode ser o quarto localizado no Estado. Em todo o Brasil estão registrados 56 meteoritos, apenas 21 desse tipo. Mas não foi possível terminar a data da queda.
Segundo o geólogo Antônio Pedro Viero, do Instituto de Geociências da UFRGS, é provável que a rocha pertença ao núcleo de algum planeta. Antes de ser levado ao Museu Nacional, no Rio de Janeiro, o meteorito vai passar por análises químicas no Canadá, cujo resultado vai ser publicado numa revista científica para registro oficial.
Esse não é o primeiro meteorito encontrado no Vale do Taquari. Em 1937, uma queda de uma pedra foi vista em Putinga, cidade a cerca de 20 quilômetros de Arvorezinha.
Geólogo crê na chance de região registrar outros casos
O meteorito, de mais de 200 quilos, provocou buracos profundos no solo e até hoje atrai curiosos ao município. Uma pequena parte da pedra – apenas 1,7 quilo – encontra-se exposta no museu local: é o único fragmento recuperado pela prefeitura até hoje.
– É provável que existam outros e, por isso, os moradores devem ficar atentos. Este é um registro científico muito interessante – diz o geólogo Ari Roisenberg, da UFRGS, que também esteve na cidade.
