Round object that moved from side to side and in a straight motion, disappeared and would reappear during a crystal clear nightWhile in our backyard admiring the clear night and all the stars and planets that were so bright and brilliant my husband and I both noticed (since we were pointing and looking at the same area) what looked like a star (small, less bright, round in shape) but was moving fairly quickly and smoothly in a straight motion. After a few seconds it would disappear and would reappear to the side of where it just disappeared and would move in another quick, smooth straight motion, then slowly disappear and reappear again to the opposite side. We both realized it couldn’t be a plane b/c there were no flashing lights, no noise and planes can only move in a straight forward motion, not move over to the left or right. We weren’t sure what to think but wanted to report it so it was documented.
