Object with lighted sphere in center and red/blue/green triangles on either sideI was approaching Braddock Road from Sequoia Farms, about to make a right and something over my head caught my eye . Living so close to IAD I'm used to constant air traffic over my head but this was very different.The center of the object was a spherical shape that lit up for a few seconds then went dark, lit up again slowly then would go dark, in a seemingly random order. There were two triangular shaped pieces on either side, kind of flanking the center sphere. The triangles on either side had red/blue/green lights that kind of "chased" and went around quickly. It seemed very close, almost just above the trees. I watched for a few minutes but soon cars were behind me and I had to move, so I don't know how long it was there.
