UFO Hovering Over Long Island New York?

I shot this video on December 18th, 2010, of what seems to be a very mysterious light hovering in the sky, right above where the ocean meets the shoreline, in Long Beach, New York.

I'm not trying to hoax anyone or waste anyone's time, and you'll clearly be able to see that this footage is not doctored or manipulated in any way.

The only editing I did do was stated at the end, where I zoomed in.
