UFO during July 4th, 2011 in Cache Valley, Utah

This UFO video from YouTube shows an object that continuously grows brighter and then dies out, seemingly hovering high in the sky.  It moves occasionally, but not by much.  It might be a bit out of focus, but I’m not entirely sure if that’s just how it looks in general.

As you can see, there are fireworks in the background, but they are much lower than the UFO, plus there aren’t any firecrackers I know of that can do this (not that I’m a firecracker expert…)

The description of the video on YouTube says that the video was originally 7 (seven) minutes long but was edited to cut out blurry parts.  It proceeds to say that no other editing was done on the video.
