Nah it was way after sunset, it was definitely a point light source, the repetitions followed a strict schedule (I had started watching the time after the third one), and it had the steady motion you'd expect of an object with mass propelling itself that an illusion wouldn't necessarily have. It really seemed like a fast plane in the distance at night, and I wouldn't have given it a second thought had it not been for the disappearance or the repetition. I believe I saw a puff of light when it winked out, but it was hard to tell. The mountains it appeared behind were 10 miles away, and it was probably further than that. The town was surrounded by various explosives testing ranges. Occasionally everyone would hear the loud thump of a bomb being test during the day. Mythbusters was known for using some bomb range nearby. I'm pretty confident it was some kind of military or scientific test I saw, I'm just mainly curious about the specifics.
