UFO sighting
Mysterious sky visitor
A UFO sighting is an instance of someone observing an unidentified flying object—something in the sky that the observer cannot explain.
The term doesn't imply alien spacecraft, though popular culture has cemented that association: She reported a UFO sighting to the local news.
Most sightings turn out to be aircraft, satellites, weather balloons, or atmospheric phenomena.
