HI-TECH computer imagery will be used to dissect video footage of the moment UFOs were captured on film above Bolton.

Experts will examine pictures, taken last summer, which show unexplained bright lights.

In a special conference to be staged at Bolton Town Hall this weekend, organisers say exclusive footage - showing UFOs recorded across the globe as well as around Bolton - will be examined on screen.

Guest speakers will be Graham Birdsall and Russel Callaghan of UFO Magazine and Granada Television's new series 'Origin Unknown'.

Caroline Ashworth, from Bolton Museum and Art Gallery, said: "We are expecting more than 100 people at the conference which is being staged in the lecture theatre under the museum.

"It is the first time that we have held such an event, but it promises to be out of this world!"

Saturday's conference follows the new science-fiction series on television which featured the alleged Bolton UFO, which several people not only saw but captured on film in the direction of Winter Hill. Caroline said: "This was an exciting event spotted by people across the North-west.

"The latest computer equipment will give an in-depth analysis of the event, re-enacting the moment when UFOs embraced the Bolton skyline."

The conference is also being staged to promote the Bolton Museum and Art gallery exhibition "The Unexplained: Photographs of the Paranormal", which runs until April 24.

Caroline said: "Bolton seems to be going UFO mad. We've had a lot of interest in the exhibition."

Tickets for the conference are available at the town hall, priced £6 or £3.50 concessionary.
