Meteorite seen to fall. Such meteorites are usually collected soon after falling and are not affected by terrestrial weathering (Weathering = 0).

Beginning in 2014 (date needs confirmation), the NomComm adopted the use of the terms “probable fall” and “confirmed fall” to provide better insight into the meteorite’s history.

If a meteorite is not a fall, it is then considered a “find”, though some prefer the term “unobserved fall”.
