It is clearly seen, for example, at the marine landscapes. This illusion may occur as in the photos (especially black and white) and by direct observation.

Ordinary satellites, which often look like single, not very bright luminous dots moving smoothly in the night sky, are quite often mistaken for UFOs. After the Starlink satellites (near-Earth satellite systems developed by SpaceX, in order to create a cheap and high-performance satellite Internet communication channel and technical transmitters for receiving and transmitting signals from earth and orbit) were launched, it became possible to observe groups of satellites (up to 60 pieces) flying one after another.
