(meteorobs) Lyrids from Colorado

[Chris Peterson]

All trains are essentially infinitely thin, since they are narrower than 
the angular resolution of the camera (or of our eyes). So the apparent 
thickness in the image is a consequence of diffraction and the 
brightness of the meteor. In fact, I use the thickness (the size of the 
head in any individual frame) to estimate the magnitude when the 
brightness results in saturation (which happens at about mag -4).
