Bright lights followed by dimmer lights. After lights came a glow. No noise hovered. Lasted about 2 mins.took dog out for a walk, looked towards hills,saw an unusual light and thought it was the moon behind some clouds. Then saw the light source move and got lighter. As the lights were getting brighter the following light dimmed. This took place for est. 1.5 mins. After lights stopped a dullish glow came from under object. Could not see any objects in the sky. It was a clear night where the stars were shinning, but in the direction of where the lights came from I could not see any stars at all. These light came from a source that had no noise and kept its position for the duration of time. As stated could not see any object but where the loights were there are no buildings as it was sighted above a hill over looking the Towy Valley
