The Great Daylight Fireball-1972 aka Grand Teton Meteor

The Great Daylight 1972 Fireball (or US19720810) is an Earth grazer meteoroid which passed within 57 kilometres of the surface of the Earth at 20:29 UTC on August 10, 1972. It entered the Earth's atmosphere in daylight over Utah, United States (1430 local time) and passed northwards leaving the atmosphere over Alberta, Canada. It was seen by many people and recorded on film and by space borne sensors.[1]

By comparison, the Otto C. Winzen developed balloon reached 51.8 kilometres in 1972 and Low Earth Orbit satellites orbit from about 200 kilometres from the surface of the Earth.

Analysis of its appearance and trajectory showed it was a meteoroid about 3 (if a carbonaceous chondrite) to 14 metres (if made of cometary ices)[2][3] in diameter in the Apollo asteroid class in an Earth-crossing orbit that would make a subsequent close approach to Earth in August 1997.[1] In 1994 Zdenek C
