Dublin, Ireland. I don’t know if you could describe this as a “UFO” sighting as what I saw appeared to be with the stars (and same size) in the night sky. As far as I remember I was around 15 years old and was looking up at the sky. It was a very clear night and all the stars were visible. I notice 2 stars about a finger apart as you hold out your hand from your face, one star would shoot a white object to the other and the other would in turn shoot it back. This went on for about one minute when one of the stars went out. The other star remained. Neither star moved during this event.
