Eyewitness states: From the SLC avenues mid September 2022 at sundown, I noticed a fairly large triangular object hovering in the sky. It was first floating stationary but moving kind of wavy. It then proceeded to slowly move North. I captured a total of 4 videos of approximately 1 minute 30 seconds each. The object kept floating North and then seemed to dissapear from view. The object was definitely triangle and guessing the size could have been around 60-75 ft in length. The location when first spotted was just above the high rise buildings in downtown Salt Lake. It appeared to be about 1250-1500 ft in the sky.
