strange "star" changing colors and moving slightly but remaining in the same part of the sky for 20+ minutesWhile walking my dog at about 10pm I noticed a red "star" in the NNE sky as I was looking at the beautiful star lit night sky. As I watched this "star" I noticed that it was not red, but it was infact just a bright star...then it turned green, then red then back to white. I thought it could perhaps be an aircraft traveling toward me and that is why it looked like it was stationary but then it moved slightly to the left (about an inch in my view, which could be many miles in the sky) then back to the original position. I went and got my daughter to come out and look at it and it did the same thing while she was with me....turned red, then green, then clear for a while then moved slightly to the left and this time up then back to the original position still changing colors. I even got out binoculars and while it still looked like a star I could see the color change easier thru the binoculars than with my naked eye. Not saying this is a! UFO, but it was definitely something strange....it stayed in the same spot for about 20 minutes (except for the 2 times I saw it move) then I went inside. I do not know exactly how long it had been there or how long it stayed after we went inside. There were planes in the area as we live about 15 minutes from the airport but this didn't move like a plane and looked like it was farther away then when the planes fly over.
