I was in my back yard which is in the water and faces downtown Miami. It's was a clear night with scattered clouds and a quarter moon. I noticed a transparent object with a jelly fish like type movement. It also had a beam of light. There were also 7 other people with me. It was real close when I noticed it and then it moved in the distance looked like wings. Then it moved through the clouds and had a small light beam. It disappeared into the night after around 7 minutes.
