I was on break at work when I noticed a light in the sky that looked like it didn’t belong. I had never seen lights like that on any aircraft before. It was decently bright and would slightly dim and then return to normal on a perfect cycle. The object didn’t move very much at all; it probably stayed within the size of a quarter at arm-length away. Then all of a sudden the object appeared to move straight up until I lost sight of it as I was under an awning.
