Pictures of your Meteorites

I shot a couple of pictures of a few of my favorite meteorites. This one is my 24.8 lb Campo del Cielo which fell about 4000-6000 years ago in Argentina, about 500 miles north-northwest of Buenos Aries. Latitude 27 degrees 39 minutes South, Longitude 61 degrees 44 minutes West.

These are my fragments of the Sikhote-Alin Meteorite that was an observed fall on February 12, 1947 in Russia, about 270 miles northeast of Vladivostok. Latitude 46 degrees 9.6 minutes North, Longitude 134 degrees 39.2 minutes East. The fragments shown are 200 and 250 gr

The Sikhote-Alin meteorite fell during daylight at 10:38 a.m. local time. Witnesses reported a fireball that was brighter than the sun. It came from out of the north -- about 15 degrees east of north and descended at an angle of 41 degrees. It left a trail of smoke and dust that was 20 miles long and lingered for several hours. Light and sound of the fall were observed for two hundred miles around the point of impact.

The speed of entry was estimated to be 14.5 kilometers per second. This is about 8.7 miles per second or 31,000 miles per hour. As the meteorite entered the atmosphere some of it began to break apart. The group of fragments fell together. When the descending group of meteorites reached an altitude of about 3.5 miles, the largest mass apparently broke up in a violent explosion. The fragments scattered over an elliptical area of about a half a square mile. The largest fragments made small craters and pits. One of these measured 85 feet across and 20 feet deep. The larger craters are located at the far end of the strewn field.

Great photos guys. Thanks for sharing.
There are some very nice specimens here.
My small but growing collection is quite modest,
but I will try to take a few pictures to post in the next few days.

That's a beauty, Michael.

Several years ago, my Mom bought me a 440gm Octahedrite. I decided I would like to aquire just a few samples of the major types but I forced myself to stick to around $100.

My collection is small (just 4) but it gives me great pleasure to posess these little bits of very well travelled rock.

I've started a small collection as well. Here's My center piece -- a nice example of a Campo, 20 pounder.
