2006-12-02 - West Dundee, IL - Formation

String of 6-7 lights equally spaced apart, about 1000 ft up moving quietly West to East in the night sky.

I was walking in my back yard, letting my dog out and getting some firewood. I looked up to see how the stars looked on this cool crisp night when I noticed what appeared to be a flock of "lit" birds...but turned out to be a string of lights, approximately 1/3 high up in the sky. If I had to guess less than 1,000 ft up.

My dog began barking but other than that the sky was dead quiet. The 6 lit objects almost looked like stars but were a dull orange or pink tone and moved in perfect unison. This could have been one object. The object moved from West to East at a slow but steady pace.

I have tried to think about all possible alternatives and ratonalizing this but cannot determine what this is. It definitely was not a natural occurrance and has shaken me.
