The sikhote-Alin meteorite fell during the early daylight hours at 10:38am on Feb 12th, 1947. Onlookers witnessed a fireball that was brighter than the sun which came from the north, about 15 degrees east of due north. It decended at an angle of roughly 41 degrees. A smoke trail that came with it was over 20 miles long which lasted for hours and the sound of it entering the atmosphere at such a high velocity was heard as far as 200mi away.

There are two types of specimens that come from this Sikhote-Alin meteorite. The first is your stereotypical meteorite that one would think of when the idea of a rock falling to earth is mentioned. Ablated cavities fill the surface with regmaglypts (thumb-print-like) all over its architecture 

The second type of specimen comes from the initial mass’s fragments. These show the violent effects of being ripped from the original or being blasted from the impact center after hitting the ground. Ones similar to being “cold-worked,” the fragments probably came from the explosion which happened 3.5 miles high. Many look like shrapnel after violent explosions while others look similar to shields in their shape with flatter orientations.
