Fell 2003 February 1–3

Ordinary chondrite (H5)

A 414 g stone was discovered on February 4, 2003 in the delivery center of a pharmacutical company by workers searching for the cause of a leaking roof. The meteorite penetrated the steel sheet roofing and plasterboard and hit a roller conveyor belt then fell to the floor. The fall must have occurred after the center closed on the evening of February 1. Several people in Hiroshima observed a fireball around 22:30 on February 1. Classification (A. Okada, RIKEN; S.
