Meteorites from recent amor-type orbits

We report here the discovery of a recent meteorite shower in Antarctica, the members of which have very high natural thermoluminescence levels. It is apparent from these data that the shower has been on Earth only a short time (approximately 1000 years) and the meteorite probably came to Earth through rapid (less than 10 exp 5 years) evolution from an orbit with perihelion greater than 1.1 AU, similar to Amor asteroids. Only a very small number of meteorites, including a few modern falls, appear to have had similar orbital histories.
