A bright light that hovered and then disappeared below the treeline.I was a few miles outside of Warsaw, Poland in a summer home in a desolate part of the country right next to wooded lands with my mom, sister, and family friends. One evening, I believe the 15th of July, we were sitting outside. It was about 10:00 p.m. I was getting back from the horse stable right outside the fenced property of the house with the man who owned the summer home, a family friend. As we were getting back and approaching the house, I noticed my mom was holding our camera and recording something. Her, the family friend, and I were the only ones outside at the time. I asked my mom what she was recording. She then pointed I believe Southward right over the treeline of the nearby woods. As the family friend and I proceeded to look in that direction, i suddenly noticed a diamond shaped white light. It was completely silent. It was positioned in one location, without moving even the slightest bit in any direction. I only saw the light, and no other structure around it, making it impossible to be a helicopter or any other type or air vehicle or structure. We proceeded to watch the light for about 3 minutes. It remained unchanged. Then, it became a little brighter, and I noticed the color of the object was changing to a sort of bluish light. It then proceeded to move downword toward the treeline at an unusually slow, but constant speed. It seemed to move straight down without any other movement. Then, it disappeared below the treeline. After that, we went our ways, but I kept looking in that direction every few minutes. Unfortunaltely, nothing else happened that I noticed.((NUFORC Note: Date is approximate. PD))
