Green streaks in the sky?
 

Driving home from work tonite I saw a green streak followed directly by another green streak. It was headed toward the horizon at a downward angle. Anyone know what this could have been?
There has been alot of activity during the twilight hours near my house. I live near a major airport so, not sure whats going on but it feels like something is trying to keep a close eye on us here.
I ve seen my share of shooting stars before. Ive never seen a green one. Argon in the atmosphere???
