A first  meteorite (L4,S2,W0) of  the S\u00e3o Paulo bolide, seen at about 11:35 (UTC) on 9 January 2015, was found on the same day at location 23\u00b009\u201936″S, 48\u00b010\u201952″W <\/a> , 6.4 km west-northwest of Porangaba, S\u00e3o Paulo in Brazil. The meteorite weighs about 450 grams and has a diameter of about 8 cm. Independent of the find the astronomer Carlos Eduardo Augusto de Pietro from Goi\u00e2nia (GO) had calculated the trajectory and possible strewnfield based on three photos of the dust trails (from the cities of Len\u00e7\u00f3is Paulista*<\/strong><\/a>, Ja\u00fa and Tatu\u00ed*<\/strong><\/a>), radar images and an eyewitness report.<\/p>\n

On January 9 2015 Julio Caravalho da Silva*<\/a>, the caretaker of Paulo Gama’s*<\/a> property, and his son Eduardo were sitting on a porch when they heard a long thunder with rumbling noises in the sky and about five minutes later Julio heard the sound of two objects hitting the ground, one in the close proximity and a moment later one further away. Three meters away from Gama’s house Julio Carvalho da Silva found the meteorite buried in a small impact crater, about 10 cm wide and 25 cm deep. Gama contacted Maria Elizabeth Zucolotto, curator at the Museu Nacional, Rio de Janeiro, on the same day by sending a photo of the meteorite via email.<\/p>\n

\"Fall<\/a>

Renato Cassio Poltronieri, living in Nhandeara (SP) was informed about the fall as well. It’s the first time in Brazil that a meteoroid trajectory and strewnfield could be calculated based on photos and witness reports. Renato Cassio Poltronieri and Maria Elizabeth Zucolotto arrived in Porangaba on January 17, 2015 and on January 18 went to the calculated fall area. Julio did not dare to touch the stone and his son Eduardo called Paulo Gama who checked whether the stone was hot and by doing this was the first to touch the meteorite. The fall location was actually very close to the fall location calculated by Carlos Eduardo Augusto de Pietro. The meteorite is now in the property of Paulo Gama. It has not been decided what will happen to it. A small chip was removed to have it analysed at the Museu Nacional in Rio de Janeiro. A specimen of 20 g is curated at the Museu Nacional.<\/p>\n

Another meteorite search expedition to find a second meteorite which might have fallen was undertaken between January 30 and February 1. On February 7 Renato Poltronieri was contacted by Jos\u00e9 Maria of Porangaba who, together with his nephew Rafael N. Ferreira, had found a second meteorite weighing 520 grams on 10 January 2015. Poltronieri, his wife Cristiane and Gabriel Gon\u00e7alves travelled to Porangaba to see the meteorite and negotiate with the owner about what to do with it.<\/p>\n

Jos\u00e9 Maria gave a 131-g-fragment to Poltronieri, which was then cut into five parts. “It was cut into 5 parts. One was for Dr. Beth Zucolotto, scientist at the National Museum, one piece for Gabriel Gon\u00e7alves from the Universidade Federal de S\u00e3o Carlos (UFSCAar) to be analyzed and as a donation to a new museum, […] the other three parts were given to me, Carlos [de Pietro (from Goi\u00e2nia)] and Marcelo [Domingues (from Bras\u00edlia)]. My part weighs 30.4 grams”, said Poltronieri. Recently, half of the remaining meteorite was donated to Poltronieri, the rest will be offered to collectors. Andr\u00e9 Moutinho has recovered two additional pieces (3.5 g<\/a> and 2.9 g<\/a>) Porangaba<\/strong><\/a> was officially registered in the Meteoritical Bulletin Database on 24 May 2015 *<\/strong><\/a>.<\/p>\n
