Shape: Changing shape | Duration: 1 hour

We spotted a very shiny object in the sky, at a pretty high altitude, hovering over the area where the air force base is located. We thought it might be a weather balloon reflecting the sun, but when we looked at it through binoculars we realized that it was a sphere, with two small spheres that seemed to be rotating around it, and what we originally thought were reflections was a light originating from the central sphere. it was very bright, but the edges of the light looked prismatic, in that the light was diffracted into colors at the edges. it hovered for at least half and hour, then drifted a little, which made us decide that it might be some sort of balloon after all. But then, it started moving toward the west at an increasing rate of speed. As we watched, it literally started to change shape, elongating and taking on a triangular shape. At first the light and reflectivity of the object were intense, but then it faded to a dark grey and essentially looked like a flying grey triangle, flying upright, so we could see the complete shape. We followed it until it disappeared from sight. About twenty minutes later, it was back but at a much higher altitude, hovering where it was previously. It stayed there for about another fifteen minutes, then it changed back into the triangle. A small puff of what looked like smoke appeared suddenly, and then the shape shrank rapidly and disappeared.
