Typically when someone in our group comes upon a meteorite, we all gather to it to help in the collection process and to look for other pieces of the same specimen. Being careful not to touch the meteorite, or get close enough to breathe on it or drip a nose on it, we get the meteorite into a sterile bag as quickly as possible (usually by putting the bag over it). The meteorite is measured, and sometimes photographed, and it's size and color and possible classification is noted. A small aluminum tag with an ID number is also inserted into the bag, and the whole thing sealed up tight.
