From UFO's Northwest, July 30, 2011, 40 Miles Northwest of Boston, in Lowell, Massachusetts.
The witness stated: "It was in the sky for 2 hours while I watched. I am not sure of the total time. It made no sound and just went from left to right and back and changed colors. At one point it put a light on the ground like a helicopter at 3 different times, but this was before I was filming."
This is not a Chinese lantern. This is something Unidentified.
