Driving East bound on US 60 between Val Vista and Higley at 1923 hours I looked up to my right and saw a bright amber/orange object approx at a 40 degree angle off of the south/eastern horizon. If I held my fingers up to measurer the object, it would have been an inch between my fingers which may help give an idea of the distance of the object. It was difficult to estimate distance due to the darkness. The object looked like what a disc type object would from a side view and it was an extremely bright amber/orange and looked as if it was emanating light from the inside and had a soft glow around it. There was also a thin reddish line on the bottom. As I said, it was dark out which made this object very easy to see. Suddenly the object shrunk in on itself and disappeared leaving 3 or 4 tiny blinking multi colored lights which also quickly disappeared. This lasted approx 30-35 seconds. I am sure this was not an airplane and it was definitely unusual.
