Re: (meteorobs) Leonids - colors?
Hello, Micheal and MeteorObs-er
In generally, photographs record meteor colors like "start out green then go to
the orangish-red color before terminating."
Meteor photograph expose longer time(10 seconds and so on) than eye-witness
(about 1/30 seconds).
So, I think your photographs recorded meteor trail, oxigen(green, 100km-hight)
lights and sodium(orange, 80km-hight) lights in atmosphere.
And human eyes can not recognize color of weak light, so less 2mag. meteor are
colorless.
