My uncle and I were standing outside on a warm summer evening. We were talking about unions and looking up at the stars. It was about 1 in the morning and the sky was very clear. We were facing south. There was a garrage in fron of us and a pear tree behind. North to South we had about 60 degrees of sky visable. To the West and East most of the sky was visable. Suddenly the stars disappeared. There was no noise. The hair on my neck stood up. All I could yell was "Did you see that?" My uncle and I compared observations, we had the same impressions. What appeared to be a trianglar shaped, unlit, solid object had block out the stars, all of the stars. The duration of the blockage was very short. The object had to be large and very close to completely block out the stars (there was no noise) or massive! I was about 12. My uncle was about 30 years older. We often spent hours night after night during the summer talking outside. Never before or after seen such an object. My uncle was unemployeed at the time but had previously worked as a surveyor for the city. I was, of course a student.
