The time was just before sunset, and the first object was a red ball. While I was watching it, it turned around, went behind itself, and was gone. I stopped in the middle of the bridge I was crossing, near MIT, and tried to find it again, but could not. I turned around, looking to see if it had moved to another part of the sky, only to see a second strange object. This one I first thought was a plane reflecting the sunset; it was long and orange. But it wasn't moving either, at first. Then it got longer, then shorter again, and then began to move in a small circular pattern. Then it stopped and began to get longer and shorter again. When I got to the end of the bridge, it was hidden behind a building. I walked further to see if I could catch it again, but it was gone. By this time the sun was beginning to set and the stars were coming out. I saw one bright light, which I at first assumed to be a planet. But then, I noticed a small red light attached to its right side. The red light went out, and a blue one appeared in its place; this one too soon faded away. Shortly thereafter, I lost sight of it and did not see it again.
