Unknown craft observed hovering near nuclear power plantMy wife, daughter and I were staying at a bed and breakfast in Glen Rose, TX. Our room was on the 2nd floor and had a balcony. My wife couldn't sleep and went out on the balcony at approximately 4AM. She woke me up saying she was observing a UFO. I went out and observed the object. Circular, stationary in the sky, estimated altitude 1000 - 2000 feet, approximately 5 miles away. There were alternating red and green blinking lights coming from the object. There was no sound. Every couple of minutes it appeared to emit a ring of white vapor. My wife also woke my daughter, The three of us watched the object until it could no longer be seen in the morning light. The next morning I realized that from where I had seen the object, it would have been near a nuclear power plant located near Glen Rose.((NUFORC Note: Based on the description provided, we believe that a twinkling star is the first possibility that would have to be ruled out. PD))
