A shower of small stones (>1000 individuals) fell near the Yellow River after a brilliant fireball with smoke and sparks terminated in a loud, resonating explosion; the fall ellipse measured about 10.5 x 4.3
km, oriented east-west; the largest recovered piece weighed 2.7 kg, and the total mass is >100 kg; one fragment was reported to have penetrated a roof and landed in a pot on a stove; classification and
mineral analysis (Chen Yonghen and Wang Daode, Guangzhou Institute of Geochemistry; Wang Ruitian, Heze Bureau of Seismology, and A.Rubin, Univ. of Calif., Los Angeles); the meteorite has been widely traded
