Official Aiquile fall coordinates (18°17’4″S, 65°8’39″W)

In the evening of November 20, 2016, at ~5.45-57 p.m. local time, three to four detonation sounds were heard by the Quechua villagers in the area around Aiquile in Bolivia’s departamento Cochabamba. A daytime bolide leaving a white ionization trail was seen in the sky by dozens of people. Its main fragmentation event occured above the Tabla Mayu community. Initially it was believed that there had been a plane crash or an earthquake. The fall of a large meteorite, weighing 36.3 kg (47 × 17 × 26 cm), was witnessed by Calledonio Vizaga about 500 m from his own location in the Cruz Loma community. Vizaga recovered the meteorite and on 21 November members of the Aiquile government (Luiz L. Arnez, Marco Cardona, Franz Navia, William Rodriguez,and Jesus Yave) brought the mass to the Museu Municipal del Charango in Aiquile. On the same day the Gobierno Autónomo Municipal de Aiquile informed the public about the meteorite falls and published the first photos of found masses. Roberto Soto found two masses of 2.26 kg and 0.565 kg which were brought to the Museu Municipal del Charango (Aiquile) as well. Two other found masses weigh 5785 g and 1285 g and are in private hands. A child is reported to have found fragments of a meteorite which had fragmented on impact on a terrestrial rock in the community of Tabla Mayu (Chago K’asa). On 22 November the mayor of Aiquile, Luis López, reported that many meteorites had fallen the communities of Tabla Mayu (Chago K’asa), Panamá, Ch’awar Mayu (Panama), Barbechos and Cruz Loma in Cochabamba. The local government had sent communal staff members, including Marco Cardona, to the fall locations to register GPS coordinates and asked the local population to go to the Museo Del Charango in Aiquile to have their meteorite finds registered. Eyewitnesses as Fidel Torres, who was working outside fixing the roof of his house, report that they heard three to four detonation booms which sounded like dynamite explosions with the last sounds reminding them of machine gun fire. On 29 November 2016, in its LEY MUNICIPAL N° 069, the municipal government of Aiquile declared the Aiquile meteorites a ‘patrimonio municipal’, a natural municipal heritage, because of the meteorites’ ‘invaluable valor histórico – científico’, their historical and scientific value, as well as their ‘atractivo turístico’, their potential as future tourist attractions. Act N° 69 de-legalized any commercialisation and trafficking of Aiquile meteorites or their fragments and called for an organized systematic search for meteorites as well as a control and safeguard of the strewn field area. The municipal executive of Aiquile is asked to take all the necessary actions for the meteorites’ recovery, preservation and protection, in an appropriate place that guarantees an adequate conservation. A commission of the Ministerio de Minería travelled to Aiquile to analyse the meteorite fragments. A search team of SERGEOMIN (Servicio Geolgico da Bolivia / Miguel Angel Muriel, Coria Guillermo), the local Aiquile government (Marco Cardona), André Moutinho, Jose Maria Monzon, and Sergio Medina was formed and a systematic search was performed during which some smaller masses including a 98-g-specimen (18°17’09.8″S, 65°08’34.1″W) were found. By 16 December the type specimen (40 g), cut from the 98-g-mass found by André Moutinho, had been classified as an H5-chondrite by Prof Maria Elizabeth Zucolotto (Museu Nacional/UFRJ, Brazil) and analysis data were sent to NomCom by Moutinho on that day. On 21 April 2017 AIQUILE was officially registered in the Meteoritical Bulletin Database.
