Someone posted a blurry video of a red light moving around, disappearing, and reappearing in the sky at the local Walmart. I had to break it to them that it was the red light on top of the water tower across the street. There were no other lights, and the stars weren't visible there, so I could understand seeing a UFO moving around in the autokinetic effect. A very fun optical illusion to play with, or deeply concerning to someone who doesn't know about it. Unnatural motion seems to get the highest weight in these sightings, so I wouldn't be surprised if this effect is the #1 culprit. Imagine how the ISS or even any satellite would look with that effect, floating around as it goes from dim, to bright, to dim as it crosses the sky.
