I saw a fireball
A fireball is a meteor brighter than the planet Venus: a piece of space rock, usually no bigger than a pebble or a fist, burning up as it plunges into the air at tens of kilometres a second. Tell us what you saw. Reports from several places let the path through the sky be worked out, and sometimes where any surviving pieces fell.
Write it down as soon as you can, before the memory fades. Rough answers are fine, and you can leave out anything you are not sure of. To judge height in the sky, hold your fist out at arm's length: it covers about 10 degrees, so the horizon is 0 degrees and straight overhead is 90.
Your report
If you find a fresh meteorite
A stone that has just fallen is valuable to science because Earth's air and water have not yet changed it. Photograph it where it lies with something for scale and note the exact spot. Pick it up with a clean plastic bag or foil rather than bare hands, keep it dry and do not test it with a magnet, which can scramble the magnetic record inside. Always ask the landowner's permission before searching, and check the law where you are.
