The meteorite weighs about 420 (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

He informed Renato Cassio Poltronieri, living in Nhandeara (SP). 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 after Zucolotto had been informed immediately after the fall by the property owner Paulo Gama*<\/a> that a meteorite had been found earlier.<\/p>\n

On January 9 Julio Caravalho da Silva*<\/a>, the caretaker of Gama’s property, and his son Eduardo were sitting on a porch when they heard a long detonation in the sky and about five minutes later Julio heard the sound of two objects hitting the ground, one close by 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.<\/p>\n

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 has been removed to have it analysed at the Museu Nacional in Rio de Janeiro.There are unconfirmed speculations about the ~ 420g meteorite possibly being an L5 or L6.<\/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 had found a second meteorite weighing 425 grams. 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 131g-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,\u00a0Carlos [de Pietro (from Goi\u00e2nia)] and Marcelo [Domingues (from Bras\u00edlia)]. My part weighs 30.4 grams”, said\u00a0Poltronieri. Recently, half of the remaining meteorite was donated to Poltronieri, the rest will be offered to collectors.<\/p>\n
