A sighting is when you see or notice something unusual or new. It could be a rare animal, an unknown person in your neighborhood, or even a UFO.
When people talk about sightings, they usually mean that they've seen or experienced something unexpected and might want to share it with others. For example, if someone spots a bear wandering through their backyard, they'd say "I had a sighting of a bear today." The same applies to reports of unusual phenomena like strange lights in the sky or alien encounters – these are often called sightings too.
The act of catching sight of something, especially something searched for.
Example: There will be a small prize for the first sighting of a seal.
