I was driving southbound on the Wilbur Cross Parkway near Orange, CT and observed a stationary object high in the sky that appeared to be metallic and reflecting light. It was over the treeline of the northbound lane and I lost sight of it for about 30 seconds but witnessed it again where the treeline was shorter. I was about 3 to 4 miles from the Sikorsky bridge so I figured when I arrived there I could view it better however it was no longer in the sky. There were a few cirrus clouds and it was near sunset but there were some behind the object My first impression was that it was a star but then when I caught other glimpses and it appeared to be reflecting light rather than creating it. The altitude of the object appeared to be 15-20,000 feet and it seemed to be over the Stratford side of the Wepawaug River opposite Sikorsky. I could not take a picture because I was driving.
