Hi Bernd and List

diameter ca. 2 inches, color greenish, duration seveal seconds
possibly a magnesium rich meteor? A huge Enstatite maybe? Exciting! I hope
something is found
As layers of the meteoroid abrade and ionize, the color of the light emitted
may change according to the layering of minerals. Colors of meteors depend on
the relative influence of the metallic content of the meteoroid versus the
superheated air plasma, which its passage engenders
Green colours are not due to the meteoroid composition, but to Oxygen in the
atmosphere (the so-called "forbidden" Oxygen line).
