Top British UFO hunter Philip Mantle, former director of investigations for the British UFO Research Association, receives reports on a daily basis - some dating back decades.
Philip, 60, of Pontefract, West Yorks, said: “UFO reports in the UK have been coming in at a steady rate compared to other years.
“The peak in UFO sightings is usually at the end of autumn.
"Why this is no one knows.
“The witnesses to these events are usually encouraged to report an old UFO sighting when they see something else.
“I personally have received, this year, a mixture of old and new UFO reports.
“Most of the reports that have landed in my office have come from the north-east of England during February and March. Why these are, again, no one knows.
“The oldest report that I've personally received dates back to 1955 from Batley in West Yorkshire."
Cheryl reckons the best time to see a UFO is on a Saturday - by the seaside or a lake.
She added: “People ask me all the time how they can see UFOs, I tell them to turn off their phones and stop yakking.
“Five per cent of people filing a UFO report neglect to enter the city where it was seen.
Another thing we discovered is the vast amount of UFO sightings are around great lakes and sea coasts.
“Saturday is the top day of the week for sightings. And drugged and drunk people don’t fill out UFO reports."
Eastenders hardman Danny Dyer once made a documentary on BBC3 called 'Danny Dyer: I believe in UFOs' in which he referred to aliens as "that mob up there”.

He travelled around the UK, America and South America in his quest for the truth.
