Amo - L5 Ordinary Chondrite - Slice - 6.68g - USA (Indiana)

A 6.68g slice of Amo, the final witnessed meteorite fall in the United States in 2024. It is presented in a display box with our specimen label and a card from Steve Arnold of the television series Meteorite Men, one of the hunters credited with an early find that helped confirm the fall.

Amo is an L5 Ordinary Chondrite that fell near the small town of Amo, about 50km west-southwest of Indianapolis in Indiana, at around 4:05 in the morning on 10th December 2024. The fireball was reported by people in five states, and doorbell cameras recorded its bright fragmentation flashes, followed by sonic booms. Meteorite hunters arrived within a day, and stones were soon being recovered from the ploughed fields around the town.

L chondrites are among the most common ordinary chondrites and contain less total iron than the H group. The petrologic type 5 shows that the stone was moderately heated on its parent asteroid, so its chondrules are still visible but less sharply defined than in more primitive material. Polished slices of Amo show a light grey matrix with scattered flecks of metal and rounded chondrules.

For collectors, Amo is a fresh and well-documented witnessed fall, recorded on camera and recovered within days by a well-known group of hunters. As a recent American fall with a clear recovery story, it sits naturally in a collection of witnessed falls or meteorites from the United States.
