The sighting, which happened in Grangemouth on the evening of Monday, October 12 near petrochemical giant Ineos, is now being investigated by professional UFO hunter Malcolm Robinson.
Mr Robinson, the founder of Strange Phenomena Investigations (SPI), said: “The witness, who wishes to remain anonymous, has, over the past few weeks, observed a circular white object in the sky near the refinery plant on consecutive nights beginning at 8pm and concluding at around 9.30pm.
“The witness – a respectable gentleman with a responsible job – is convinced what he saw was not an aircraft, helicopter or drone. Indeed he managed to take photographs and a piece of video footage.”
Mr Robinson, who has assisted Provost Billy Buchanan with research during the wave of UFO sightings in Bonnybridge in the 1990s, is looking for anyone else who has witnessed strange objects above Grangemouth.
