Looking over the images and movie again, I have found a few more minute details that could have something to do with uncovering the object's origin. Here's a list of what's been mentioned so far (plus my new discoveries), listed from most likely to most outlandish, starting with most likely.
Click here to look at the movie for reference to the list.
1)The object is most likely a shadow or something on or nearly on the lens, or it wouldn't be moving the way it is. In other words, it's probably not an actual object looming over the camera lens.
2)The object could be something blowing in the wind (like a piece of insulation mentioned by RJN). Notice that the shadow or whatever it is starts to move quicker when the sun starts to rise. If you've ever noticed, the wind usually starts to pick up during the daytime.
3)If you watch the movie closely, you can see that the very bottom right end of the object moves up and over, suggesting that maybe the object is rotating. Also, the top portion moves down and to the left instead of just to the left, which would also suggest a rotating object.
4)The object has a couple of small notches in it on the right side. I don't know why this would contribute to the mystery of this topic, but I listed it anyway.
5)It could be the shadow of a rotating portable solar panel

. This is very unlikely, but it would explain why it started to move faster when the sun came up.
Any other ideas, theories, hypotheses?
