Glowing orange orbs traveling across the night sky.

10-12 glowing orange balls were seen passing over the eastern end of Lawrence Ks. These orange balls were traveling from SE to NE, and were traveling roughly in a line. Several times one of the balls could be seen to pass other balls before fading out. This fading out appeared to happen when the balls would travel higher, out of eye-shot.
 It was fully dark at this time and I was walking from my neighbor's yard back to mine when I noticed them. I have never seen anything like this before. My background is educated, office worker, and not prone to believing in conspiracy theories. But this was weird!
