I was looking through binoculars on the roof and I saw a silver orb.

My father was visiting and I went up with him on the roof to try out my new binoculars. I was looking at downtown and other parts of the city. At one point I looked up with the binoculars facing NW and saw a metallic sphere flying from left to right. I call out to my dad that I see a metal sphere and I watch it for several seconds. I put down the binoculars and try to observe the orb without them. I wasn’t wearing my glasses so I couldn’t see very well but my dad points at the sky and says he sees. I look back with the binoculars and see the sphere again. It appeared to be floating without changing direction. The appearance was shiny metallic and completely spherical. Soon after seeing it the second time I lose sight of it. I ask my dad what he thinks it was and he says it’s was a drone.
