Ash Ellis, 34, is a retail supervisor who runs UFOIdentified.co.uk - which in October held the biggest UFO conference in the UK in 2021 in Preston.
The group also holds the biggest database of current-day UFO sightings reported in the UK, of which we have details of 412 sightings reported in 2021.
Speaking to the YEP, Ash revealed Yorkshire as a region accounted for 63 reports, the second highest in the UK behind the North West.
Their data is taken from UFO reports made to various organisations including UFOIdentified, MUFON (Mutual UFO Network) and BUFORA (British UFO Network).
In Leeds, seven sightings were made in 2021 according to the group.
These include one sighting in June where two thin, black curved elongated triangles, flying above nearby houses and then stopping in mid-air were reported.
In November, a dark craft with nine lights in a V shape flying silently and slowly overhead was also spotted by a Leeds resident.
The Royal Air Force was responsible for handling and recording all reports regarding UFOs until 2009 - due to 'no evidence of a threat'.
