A man who filmed an unidentified flying object from his back garden has been left scratching his head over what it could be.
Simon Carrison, 47, spotted the object in the sky from his home in College Close, Lincoln just after 6.30pm on May 23.
But he is still none the wiser as to what he actually photographed.
Mr Carrison, a courier who always takes his camera with him on his travels and posts photos of pets and landscapes, wrote on Facebook: "Usual cat stuff plus possible UFO.
"Is it a weather balloon? Was going at quite a speed hence the blur. Vanished towards the south east. No abduction noted."
He told Lincolnshire Live: "I was looking for any aircraft that I could photograph when I saw this object in he sky.
"It came from the direction of Nettleham and then headed south east.
"It glinted in the sun and it was going quite quickly. I'd say it was travelling at the height of a light aircraft, maybe 3,000 to 4,000 ft.
"I assumed it might be some sort of weather balloon but after blowing the image up I can't make out what it was."
Mr Carrison added: "I have seen lights moving across the night sky before but nothing like this in daylight."
Then on May 31 he spotted a full-sized replica Second World War Messerschmitt fighter plane being towed along the motorway.
Mr Carrison said: "I was heading to Colne in Lancashire when I got stuck in traffic on the M6 and saw the Messerschmitt on a trailer up ahead.
"It turns out it's a full-size replica owned by a Battle of Britain experience group which they take round to schools."
The truth is out there?
There have been many sightings of strange objects in the skies over Lincolnshire.
Back in 2017, Zoe Fletcher took to Facebook at about 9pm on Monday, September 4 and wrote that she'd seen something burning through the night sky.
She wrote: "Me and Nathan were in the garden and heard a strange whirring noise in the sky like an aircraft but ranging from low pitch to high pitch.
"We looked at the sky and took this picture on the right of the screen....zoom in on it if you can and shed some light.
"No, it's not a fly....it looks like something burning through the atmosphere."
In May 2017, a video of a shiny round silver object in the sky which appeared and disappeared over Boston was posted on You Tube.
Multi-coloured lights were spotted off the coast of Boston in February 2010 and five strange lights were seen over Lincoln Cathedral in broad daylight in April 2014.
And a green "fireball" flashed across the sky in Horncastle in February 2013
Astronomer Paul Money caught a glimpse of the spectacle out the corner of his eye as it disappeared to the north.
"It is difficult to say whether this was a chunk of man-made space debris or a piece of asteroid," he said.
Red, white and blue lights were seen over the coast of Skegness for up to seven hours on October 5, 1996 and radar readings were also recorded.
Nigel Watson, who has written the Haynes UFO Investigations Manual, previously told Lincolnshire Live that he believes there may be an explanation for the incident.
He said: "It looks like a combination of factors where there has been radar returns and sightings, but the two don't match up together.
"There are three separate locations where the light had been seen and this didn't match with radar data and that's the problem with the case.
"What seems to have occurred is the lights in the sky were probably Venus.
"A bright planet can look quite stunning in the sky.
"Radar returns were probably a return from a local church spire which may have caused the signals."
Mr Watson added that the RAF justified not scrambling to the incident.
He said: "The RAF concluded they were right not to scramble jets that night and that 'research has not revealed evidence that alarming or extraordinary events were being witnessed'."
He added that psychology also has a role to play within sightings of UFOs.
He said: "I think over the years there is a lack of solid evidence - there are eyewitness accounts but no one has come across a flying saucer, or it has been retrieved by the government and taken away.
"So you begin to think it's more to do with psychology and social setting.
"There was a fear of enemy invasion when people started talking about UFOs.
"The Skegness incident sounds like an important one as it has the relatively rare element of simultaneous visual and radar sightings.
"Like many such incidents, the situation can be very confusing at the time and a combination of factors can make people think we are on the verge of an alien invasion.
"In the cold light of day the nation was not at risk, but it does show that when people are looking out for UFOs, an innocent star or planet will fill their imaginations."
