A paranormal investigator is calling for a woman who reported a UFO above Kirkcaldy 34 years ago to come forward.
Straiph Wilson says the sighting on the A92, near Gallatown Roundabout, resembles a famous Perthshire case reported in the same month.
And he hopes to gather enough evidence to link the two incidents and unravel the mystery.

Straiph uncovered the Kirkcaldy case in the National Archives while researching the sighting at Calvine, near Pitlochry.
"The mysterious Fife case bears striking similarities, especially in shape," he says.
"The coincidental August 1990 date for both incidents prompted speculation about a potential link."
Details of Kirkcaldy UFO sighting
The woman, whose husband was a policeman, was on her way to hospital on August 26 when she saw something in the sky.
According to the archives, she described a very bright, diamond-shaped object, silent and hovering around 200 feet above ground.
The sighting lasted around three minutes before suddenly disappearing "as if someone had turned off a light".
It was 8.20pm and sky conditions were described as clear.
Straiph says the woman slowed down to observe the object before contacting her husband, and he enquired about other potential sightings.
Documents show there was later official involvement.
RAF Leuchars was informed and reported the incident to
HQ Strike Command at RAF High Wycombe.
