Video released for the first time shows the UFO which appeared in the sky around 3am on January 3, 2012 in Denbigh, North Wales.
Brothers Nathan and Alex Thomas saw several lights rotating in a circular formation out of the window of their home.
Nathan, then aged 14, was watching TV when he heard a loud bang from a bin being knocked over in a storm so decided to investigate.
To his bemusement, he saw the bright lights flashing in the distance over a farmer’s field.
“Upon my analysis of this fascinating footage in more detail I confirmed what the witnesses had seen and described also confirming the lights to be rotating in a circular uniformed formation, giving the impression of being fixed to a much larger circular b”

After watching them or some time he decided to wake his brother Alex, who described the lights as “amazing”.
They couldn’t hear any noise from the lights and so decided it could not be fireworks.
Nathan grabbed his Toshiba Camilo S30 hand-held camera which he’d got for Christmas and filmed the lights from his bedroom window.
After trying to work out what they had been looking at Alex then decided to wake their mum Linda and cousin Kiera who also saw the unexplained lights.
Former RAF worker Jason Gleaves studied the film using the latest computer technology.
He said: “During the video footage Nathan remarkably keep a steady focus on the objects in the distance for most of the duration, also focusing and zooming in and out on occasions capturing local housing, street lamps and foliage, which is ideal for perspective in relation to the witnesses sighting location and the unknown light sources in the distance.
“Upon my analysis of this fascinating footage in more detail I confirmed what the witnesses had seen and described also confirming the lights to be rotating in a circular uniformed formation, giving the impression of being fixed to a much larger circular base structure.
“Also frames were obtained revealing an unusual unknown shaped object, multicoloured in appearance exhibiting a full visual spectrum range.
“Near the end of the footage the lights appear to change angle to a 45 degrees angle but continuing to rotate as they did in the horizontal position before blinking out of sight for good.”
Jason managed to obtain a daytime photograph from fellow UFO researcher Gari Jones taken from the exact location and direction of the night time footage.
He overlaid a frame taken from the original footage with the daytime image which placed the lights just above the tree line on a distant hill, approximately one and a half to two miles away.
Jason, author of UFO Photo and The Ufology Umbrella, added: “At the sighting location the only landmarks are a golf course and quarry, but both set off to the left and right of the sighting location by some considerable distance (in my opinion, enough not to impede or interfere with regards to a mistaken identification) the rest of the surrounding area is farmland and beyond the sighting location for many miles.
“At one point in the footage the family pet dog is heard getting agitated and unnerved, in other similar UFO cases animals and local wildlife are often heard getting excited, but on this occasion the pet dog could be just upset because of the strange early hours commotion.
“Other possible factors and identification of the unknown light sources could be drones, but during 2012 drone technology had not been widely available to the public as they are today, so I don’t believe the lights to be drones.”
