A meteorite (32 x 23 x 18 cm), ordinary chondrite (L5,S2,W0), weighing 10.05 kg fell about 5 km southeast of M\u01cen Zh\u01ceng Xi\u0101ng (\u6ee1\u638c\u4e61) at location 33\u00b015’11″N, 100\u00b027’54″E in northern Banma County (\u73ed\u739b\u53bf\/\u0f54\u0f51\u0f0b\u0f58\u0f0b\u0f62\u0fab\u0f7c\u0f44\u0f0b), Golog Tibetan Autonomous prefecture (\u679c\u6d1b\u85cf\u65cf\u81ea\u6cbb\u5dde\/\u0f58\u0f42\u0f7c\u0f0b\u0f63\u0f7c\u0f42\u0f0b\u0f56\u0f7c\u0f51\u0f0b\u0f62\u0f72\u0f42\u0f66\u0f0b\u0f62\u0f44\u0f0b\u0f66\u0f90\u0fb1\u0f7c\u0f44\u0f0b\u0f41\u0f74\u0f63\u0f0b), Qinghai (\u9752\u6d77) province in China at around 9 pm China Standard time (UTC+8) on August 24, 2016. According to Chinese (social) news media the bright flare of the bolide was seen by Duogongmaxiang (\u591a\u8d21\u9ebb\u4e61) villagers in the region and detonation sounds were heard. The eye-witnesses first thought there had been a plane crash and informed the police which searched the area in vain. In the morning of August 25 (before 11 o’clock (UTC+8)) the regmaglypted, flight-oriented, and intact meteorite was found by two local Tibetan herdswomen, a mother and her daughter, at the bottom of an impact pit (~50 cm wide x ~100 cm long x ~40 cm deep) in the sodden soil of the southeastern 60-degree slope of a grassy hill about 210 meters from the border of Darlag County. One of them, Qi\u00e1o B\u01ceo (\u55ac\u5bf6 or \u4e54\u5b9d) was collecting (medicinal) herbs on the mountain (maybe cordyceps sinensis<\/em> fungus-caterpillar bodies or Fritillaria delavayi<\/em>) 565 meters from a herdsman’s home in the M\u00e0nzh\u0101ng river valley when she found the meteorite, whose shiny black color struck her because it looked different compared to the surrounding rocks. Qi\u00e1o B\u01ceo remembered the sound of a b\u00e0ot\u0101i (\u7206\u80ce), ‘a bursting tire’ she had heard nearby the evening before while doing farm work outside her home at an air temperature of almost zero degrees. She didn’t dare to touch the meteorite because she was afraid of radiation. She contacted the police station in Duogongmaxiang, situated 21.5 km from the fall location to inform the authorities. At 11 am on 25 August G\u00e0n J\u012bnl\u00f3ng (\u5e72\u91d1\u9f99), head of Banma County’s Land and Resources Bureau, received a phone call of the county’s public security bureau and was informed about the report. The policeman \u00c1ngq\u012bng N\u00edm\u01ce (\u6602\u9752\u5c3c\u739b) and his colleagues went to the fall location to investigate. He was the first to touch the meteorite, dug it out and declared that the rock posed no threat. Subsequently the meteorite was removed from its fall site and carried down the hill. A hail storm forced the men to stop further investigation and search for other meteorites. Banma County deputy magistrate Li\u00fa Ji\u00e0nf\u0113ng (\u5218\u5251\u950b) contacted X\u00fa W\u011bibi\u0101o (\u5f90\u4f1f\u5f6a), Director of the Laboratory for Astrochemistry and Planetary Sciences in Nanjing, on 26 August and sent photos of the meteorite. On visual inspection X\u00fa confirmed the authenticity of the meteorite. At the end of August Dr H\u00fa S\u0113n (\u80e1\u68ee), cosmochemist at the Institute of Geology and Geophysics, Chinese Academy of Sciences (CAS), Prof. Mi\u00e0o Chu\u0101nt\u01d2ng (\u7f2a\u79c9\u9b41) of Guilin University’s School of Earth Sciences, geochemist Zh\u0101ng B\u01ceol\u00edn (\u5f20\u5b9d\u6797) of the Institute of Geology & Geophysics, CAS, meteorite enthusiasts Zh\u0101ng B\u00f3 (\u5f20\u52c3), L\u00e9i K\u00e8s\u012b (\u96f7\u514b\u65af) and others traveled to Banma county to inspect the fall location in the early afternoon of 1 September. According to an informal survey around Duogongmaxiang there are apparently only 13 eye-witnesses of this meteorite fall. On 5 September, accompanied by G\u00e0n J\u012bnl\u00f3ng (\u5e72\u91d1\u9f99), head of the Banma County Land and Resources Bureau and meteorite enthusiast Zh\u0101ng B\u00f3 (\u5f20\u52c3) the meteorite was brought to the Purple Mountain Observatory’s (PMO) Laboratory for Astrochemistry and Planetary Sciences in Nanjing where on 7 September the classification process by Prof. L\u00edn Y\u00e1ngt\u01d0ng (\u6797\u6768\u633a) began by cutting a 64-gram slab off the meteorite by engineer T\u00e1n Ji\u00e0ny\u00fan (\u8c08\u5efa\u4e91). Because of the beautiful shape of the meteorite the scientists were initially uncertain about where to cut the necessary type specimen mass. In the end it was G\u00e0n J\u012bnl\u00f3ng (\u5e72\u91d1\u9f99) who decided to have it cut off at one protruding edge of the meteorite. X\u00fa W\u011bibi\u0101o (\u5f90\u4f1f\u5f6a) suggested the official name Banma<\/strong> (\u73ed\u739b), although M\u01cen Zh\u01ceng Xi\u0101ng (\u6ee1\u638c\u4e61), which is situated in the neighbouring D\u00e1r\u00ec (Darlag) county (\u8fbe\u65e5\u53bf\/\u0f51\u0f62\u0f0b\u0f63\u0f42\u0f0b\u0f62\u0fab\u0f7c\u0f44), is closer to the actual fall location. On 8 September X\u00fa W\u011bibi\u0101o submitted the classification data to the Meteorite Nomenclature Committee (NomCom) of the Meteoritical Society to have the name Banma<\/em> approved and registered in the Meteoritical Bulletin and the Meteoritical Bulletin Database.
\nOn 15 October 2016 the meteorite was officially registered in the Meteoritical Bulletin Database as BANMA<\/strong><\/a> (L5, S2). It is planned that the meteorite (currently in the Banma City Hall) will be exhibited in the collection of the Banma County Museum. The Banma county government has confirmed its intention to curate the meteorite well and to popularize scientific knowledge about meteorites. On the occasion of the cornerstone ceremony of the Shanghai Planetarium on 8 November 2016 Zh\u0101ng B\u00f3 (\u5f20\u52c3), a Shanghai citizen, donated a fusion-crusted 3-gram-fragment of the Banma meteorite to the Shanghai Science and Technology Museum. The fragment will be on public display after the completion of the planetarium, which is planned for 2020.<\/p>\n
