2 Flashing Lights In Tinley Park

1 pm sunny & clear with hardly a breeze, doing yardwork, I noticed 2 lights in the sky quite high up. They remained together but there was some movement or flashing?? I could not make it out clearly but thought it could have been 2 balloons and perhaps they were turning, with one side being reflective to cause the flash I was seeing. The speed  was minimal, they seemed to be floating along but so high up and no clouds to tell if they were going with a breeze or not. They came from the northeast and drifted southwest. I had time to run in the house, get my camera and take one photo before the trees obscured my view. I was surprised the photo shows 2 lights of different colors,one round and one more oval, and something darker between them that is difficult to make out due to the distance.
I also witnessed the 3 red lights in Tinley Park a few years ago and reported it. There were a few sightings of 3 red lights forming a triangle. My friend and I watched this one night. Then a few months later many people saw the same thing occuring on Halloween night. So many people were outside and saw it, Perhaps its this time of year we should be looking at the skies again in Tinley Park!
