2001-03-01 - New York, NY - Oval

small black oval, moving extremely slowly in broad daylight, about 6 or 7 stories off ground

When I looked out of my window, in the morning - sun shining on the top of the building across the street, I noticed what I thought was a black plastic bag floating over a six-story building. But then I noticed it was moving very very slowly, and it wasn't being whipped around. It was hovering over the building about 6 feet or so, and ever so slowly moving north, staying the exact same distace up in the air. Then I also noticed that there was no reflection coming off of it, which was also strange, since the sun was shining right on it. And it was jet-black. It continued along the top of those two building, and then went across a rather large football field - all the while moving extremely slowly and at the same height off the ground - never once being whipped by the wind or changing its oval shape. I watch it for some time as it went into the distance. To this day I can't think of any know object that fits that description.
