Lot 47 | SIKHOTE-ALIN METEORITE — FROM ONE OF THE LARGEST METEORITE SHOWERS IN HUMAN HISTORY
After having broken off its parent asteroid 320 million years ago, a massive iron mass wandered through interplanetary space until a close encounter with Earth on February 12, 1947. A fireball brighter than the Sun — i.e., it created moving shadows in broad daylight — was seen to explode at an altitude of about six kilometers over eastern Siberia. Sonic booms were heard at distances up to 300 km from the point of impact. Chimneys collapsed, windows shattered, and trees were uprooted by the resulting pressure wave. A 33-km-long smoke trail persisted for several hours in the atmosphere after impact. Sikhote Alin iron fragments were scattered over a broad elliptical area. Many of the meteorites penetrated the soil, producing impact craters up to 26 meters across; about 200 such depressions have been catalogued. Gratefully, this occurred near a sparsely populated area. A famous painting of the event by artist and eye-witness P. I. Medvedev was reproduced as a postage stamp issued by the Soviet government in 1957 to commemorate Sikhote-Alin’s 10th anniversary.

As evidenced by the regmaglypts (thumbprints) blanketing both sides of this mass, this specimen broke free in the mesosphere, providing sufficient time to experience frictional heating with the atmosphere to form the regmaglypts carved into the specimen. There is a thin veneer of fusion crust and chrome highlights along the ridges. Cleavage along crystalline planes is evident — a testament to the monumental forces exerted on this meteorite as it punched through Earth’s atmosphere as part of an extraordinary event, one of the greatest meteorite showers since the dawn of civilization. Accompanied by a magnetic armature which permits any orientation of this meteorite desired.

Christie's would like to thank Dr. Alan E. Rubin at the Department of Earth, Planetary, and Space Sciences, University of California, Los Angeles for his assistance in preparing this catalogue.
