If I recall it correct I read somewhere, that the luminous trail of a
meteor has an actual diameter in the order of 1m. Don't ask me *where*
this information came from, I think it was a result of some photographic
investigation. It means, that the apparent width of a meteor's trail shoud
be of the order of a few arc seconds.
