Upon coming home one evening in the early spring, I saw in the eastern horizon three circular objects that looked like three full mooons. They were placed in a straight horizontal line in the sky. They stood still for several minutes. I called for my Mother to come and see what I was witnessing. she saw them too. There was no sound, They were up in the sky several miles away. (we lived at the tallest point on a street and could see across to the other hills.)The two outside "moons" then moved into the center "moon". It did not grow any brighter or larger. Suddenly, the "moon" disappeared entirely.
