RE: Lost City Meteorite

Blobrana · L

The Lost City (H5) meteorite fell in Oklahoma, USA, on the 4th January, 1970.
A total mass of 17 kg was recovered.

36° 0' 30"N, 95° 9' 0"W

On January 3, 1970, four stations (Hominy OK, Woodward OK, Pleasanton KS, and Garden City KS) of the Prairie Meteorite Network simultaneously photographed the track of a meteoroid fireball. Analysis of the photographs indicated that a meteorite might have landed within an area east of Lost City. This was the first time in the US that simultaneous photography of a fireball from multiple observation points was achieved, making it possible to calculate a trajectory and delimit a search area on the ground. Six days later, Gunther Schwartz, field manager of the Lincoln NE camera station of the Prairie Network, spotted a 9.83 kg meteorite sitting in a snow-covered dirt road within one-half mile of Lost City. Three additional smaller meteorite fragments were recovered later (January 17, 272 g; February 2, 6.6 kg; May 4, 640 g). The Lost City meteorite proved to be an H5 chondrite.

On January 3, 1970, 20:14 local time, three stations of the Prairie Network (Hominy and Woodward, Oklahoma, and Pleasanton, Kansas) photographed the track of a meteor after a several year search. The meteor was the first ever photographed in the United States. Analysis of the photographs indicated the meteorite landed within a one-mile square around Lost City. Six days later, Gunther Schwartz, chief of the project, spotted the 21.6 pound meteorite sitting in a snow-covered road within one-half mile of Lost City. The Lost City Meteorite proved to be an H5 olivine-bronzite chondrite.
