Meteorites (L5) found in and around the villages Manlun (曼伦) and MANGUI (曼桂), Menghai County (勐海县), Autonomous Dai Prefecture Xishuangbanna (西双版纳) in Yunnan (云南), China. Meteorite fall at ~21:43 (CST, UTC+08:00) on 1 June 2018
Last update: 9 July 2018
A meteorite, an ordinary chondrite (L5 / 84 g), was found by a local villager in the early morning of 2 June 2018. The meteorite hit a roof tile of his house in the village of Manlun (Mànlún/曼伦) in Menghai County (勐海县) and left a hole in the roof. In the evening of 1 June while watching TV the owner Mr. Yán Xiāng (岩香) heard a sound (呜呜), similar to the sound of an airplane, and then a loud noise. Since it was Children’s Day he thought some child had thrown a rock on his roof. The following morning at around 9 am he saw the hole in the roof and found the meteorite on the second floor of the house, next to the broken roof tile. His daughter told him about the continuing coverage of the large bolide above Jinghong in a social media network. Yán wanted to know if the stone he had found was in fact a meteorite and sent a video and two photos of the meteorite to Jiang Wei (蒋维) on 2 June. The exact location of the fall has not been published so far, but the most likely fall location would be this one: 22.001284, 100.196186. Yán and his wife Yùhǎn (玉罕) initially were reluctant to sell their meteorite because they considered it ‘a gift from the heavens’. With the help of three to four guards sent by the local village committee who in turns protected the meteorite the family exhibited their meteorite, covered by a protective glass case, to the public in the garage next to their home for a few days from 7 a.m. in the morning. Many people came to ‘worship’ the meteorite. Eventually on 8 June the family was offered a high amount of money for the broken roof tile and the 84-g-meteorite. This made the family sell the meteorite to an anonymous buyer.
In the morning of 2 June a second meteorite (~ 150 g) was found in Manlun, Menghai County. It fell into the cowshed of mister Yán Guāng (岩光), the director of Manlun’s village committee, who found it after he had been told by his family that the cowshed had been struck by lightning. The meteorite crashed through a thin blue roof, hit the concrete floor, fragmented into five pieces and left a shallow fist-sized impact pit. In the morning of 3 June Jiang Wei (蒋维) and Zhang Baolin (张宝林) arrived at the fall location to investigate the finds of which six were meteorites. In the afternoon another 20 specimens could be found. On 4 June it was reported that in the meantime between 100 and 200 meteorites, many small ones (2-5 cm), had been found by the villagers of the area. Currently it is estimated that up to 2000-3000 specimens have been found. The largest meteorite is said to weigh ~ 1280 grams. Different sources claim there are some larger specimens weighing between 500 and 600 grams. Many meteorites have been sold to national and international dealers or collectors who had traveled to the area from Guangdong, Beijing, Shanghai, Kunming and others from 2 June. At least 600 locals are searching for meteorites in the rice and sugarcane fields of the area. The soil is soft and muddy after intense rainfalls hit the area from 2 June and continued on 5 June. On 4 June Mr. Jiang Wei (蒋维) sent some meteorite fragments he had bought from a local villager on 3 June to the Institute of Geology and Geophysics, Chinese Academy of Sciences (IGGCAS) in Beijing for analysis, classification and registration as witnessed fall in the Meteoritical Bulletin Database. On 8 June it was reported that a 1280-gram-specimen was found about 4.8 km from Manlun. The meteorite was found in the tea field of Yan Wenxiang’s (岩温香对) family near the village of Màngui (曼桂) (~22.041840, 100.185094). On 7 June his mother had found an impact hole and at about 2.20 p.m. Yan Wenxiang (岩温香对) took the meteorite out of the muddy impact pit. On 9 June it was reported that a 640-gram-specimen had been found in a wood near a village (22°1’4″, 100°11’41”) 1.84 km north of the fall location of the first find in Manlun. It apparently hit a larger rock on impact. Other meteorites were found in the villages Mànyàn (曼燕), Mànzhuāng (曼庄), Mànhǎilóng (曼海龙), and Mànlǎng (曼朗). On 12 June it was reported that the meteorite had been classified by Xú Wěibiāo (徐伟彪), a scientist with Purple Mountain Observatory at the Chinese Academy of Sciences, as an L5 ordinary chondrite. Apparently, on 12 June the name MANGUI (曼桂) was officially applied for at the Meteorite Nomenclature Committee (NomCom). On 9 July it was reported that the Yunnan Provincial Department of Land and Resources had sent a team to the strewn field to conduct a field investigation of the meteorite fall. The strewn field is said to cover an area of more than 10 villages and is 12 km long, 1-2 kilometers wide covering an area of about 20-25 square kilometers.

Video of the bolide seen above the city of Jinghong (景洪), moving west. At least two loud detonation sounds were heard. A muffled sound was heard in Jinghong about one to two minutes after the bolide. Mr. Li (李), a villager from Manlun, is reported to have heard a helicopter-like sound. Another video of the bolide recorded with a dashcam. The bolide recorded with a dashcam, while driving on road G214 crossing the New Bridge above the Upper Mekong (Lancang Jiang) river, from east to west, in the city of Jinghong (景洪). The camera location was somewhere here: 22°00’50.6″N, 100°48’23.3″E . Another video showing the bolide.
