White ball-shaped light heading East along the Potomac River toward Washington, DC (not a plane or helicopter)

Travelling East along the Potomac River the object appeared to come to a stop over the Mall area over Washington, DC and hover at about 3,000 feet. The light appeared to travel along the approach path to Reagan National Airport but much higher than planes usually fly and had no blinking navigational aids. The object also did not descend as if it was going to land at National. Instead it maintained its altitude until it slowed down over the Mall area and began to make a slow but sharp turn back in the direction it came from. It did this twice and came to a stop. It remained stationary for the next fifteen minutes or so. While holding its position it continuously made small moves in a left-right motion and occasionally up and down. As the sun rose, the light slowly became less visible and then just disappeared.

It appeared initially to be a white light (ball shaped) when we first noticed it then with binoculars noticed that it had subtle blue and yellow overtones.
