Disk with blue lights sequencing with white light emanating in spray in Boston MA 8/19/14 330 AMI was outside smoking holding my cat, looked up, there was a round object in the sky. Blue lights on the bottom and the lights appeared to be rotating. A white light emanated from the craft in a spray around the object. It was just hovering above Copley Square in Boston MA. It stayed there long enough for me to go outside again and take a photo, though it was too distant and too dark for my camera to catch. All it looks like on the photo is a pulsing star but this was no star and no stars have circulating blue lights on the outside on the bottom that go in sequence. Clearly this was some other kind of craft. One if many I have seen this summer in Boston MA. Though the others were spheres and multicolored.
