Re: (meteorobs) Those Electric Blue Meteors
I got a photo (& so did R. Lunsford), you can see it at
http://www.comet-track.com/meteor/geminids99/geminids99.html
I noticed that Leonids have a characteristic hue: starts out green, then
turns red. That "electric blue" Geminid is not like that. I want to
understand the detailed physics of this color hueing. Can someone point
me to a URL, which describes this? There was a post a while back,
quoting Dr. George Carruthers/NRL.
