Cylindrical UFO over Utah? Looks very much like sunlited cloud

Description from the original uploader:
"This UFO was spotted in the sky tonight at 7:19pm the sunset was at 7:10pm this is not the sun or a cloud 4 people witnessed it and could not identify what it was it looked like the top of the sun going behind the mountains but the mountains are far below as you can see and the sun was already down. At approximately 7:43 the object disappeared slowly in the same spot.

The sun or cloud would have moved since 7:19pm the object was seen even before that it took 3 to 4 minutes before that to get the video camera to film it once it was spotted.

It was the brightest thing in the sky easily seen."
