My sister and I were staying with relatives on the Inter-Coastal Waterway. We were observing the planet Mars, which was very bright that night. Very near to where we were looking, 3 star-like lights appeared out of nowhere, forming an elongated triangle shape. We watched them hover in the sky at what appeared to be a high altitude, and over the ocean. We watched them for a couple minutes. We both saw the same objects, and commented about them to each other as to what they were. I thought at first they had to be aircraft. But there were absolutely no running lights observed (I am a private pilot)...No anti-collision, strobe, nav, or landing lights. They were a solid white-yellow color. They did not twinkle like stars, and looked more like very bright satellites, but at comparatively low altitude to satellites. After a couple minutes not moving, they began to move in different directions simultaneously, silently. The two lights forming the base just seemed to disappear, while the top light forming the highest point of the triangle moved quickly straight up into space. My sister and I were stunned. It didn't frighten us, but we were amazed that what we observed was something neither of us could explain.
