For one south Norfolk dog walker, what he saw at the weekend could not be explained.
It was not an aircraft and it was not a strange weather phenomenon – he was quite clear – it was a UFO.
Jeremy le Poer Power, 66, of Smallworth Common, was walking his dog on Garboldisham's playing fields at 12.30am on Saturday, when he saw a yellow beam of light darting around above him.
He said: "It shot across the sky repeatedly for about ten minutes and was darting about in all directions above the playing fields.
"The light wasn't meeting with the ground – it finished in the skyline. It wasn't a plane or anything, it was definitely a UFO. It all went on for about ten minutes – I was very scared."
Mr le Poer Power, who walks his dog frequently at that time of night, said he had not seen anything of its kind before and was open minded about the possibility of it originating from beyond our planet.
Norfolk UFO Society committee member John Sayer, who has been researching UFOs for nearly 40 years, said it sounded an unusual sighting: "That is not a very common description. People usually talk about a ball of light or a visible craft of some kind so this is quite unique."
Mr Sayer said sightings in rural areas were common because of the lack of light pollution at night time. Sightings are often not directly up but at a low angle, and that is why rural sightings are common.
"There always seems to be an increase in UFO reports in the summer months, but it is not clear why."
Since the news broke on this website earlier this week, there have been reports of two other sightings as well as other feedback.
Mrs P Cooper from East Harling reported a similar sighting to Mr le Poer Power earlier that evening.
She said in a message posted below: "I saw a light going across the sky from left to right repeatedly. It was kind of spooky as the sky ahead of me was very dark so this showed up like a white spot of light. My son also saw it from the recreation ground across the fields."
Meanwhile, former Diss resident Tony Sandy wrote to say he had seen a UFO, described as a long black needle shape, as he was walking between Uplands Way and Willbye Avenue in 1966.
Garboldisham is midway between Diss and Thetford on the Norfolk-Suffolk border and the sighting is not the first in the area, with Suffolk named a UFO hotspot earlier this year.
