Had this UFO Sighting for less than 10 seconds while walking home from the store. UFO was a Large Boomerang shape, clearly defined and illuminated. UFO didn't look like it was moving and it quickly appeared to evaporate while going under cloud cover. This UFO was in an opposite direction of the moon (which is one day past full) so it's possible that it could be a reflection. I don't know but I don't think so. The way it evaporated in front of me made it appear like it was composed of some kind of luminous plasma. it evaporated in wisps of light. I would be interested to know if anyone else saw this? mufon cms# 120412 Park City Utah U.S 01/18/22. This region has had 886 reported UFO UAP Sightings reports to date.
