Silvery Daylight OrbI was outside at work about 6 pm. It was still daylight and a mostly sunny sky. I noticed the sun reflecting off the surface of the object. As I observed it, it was moving towards me and in a somewhat westerly direction. It seemed fairly high but it's hard to say without knowing how big it was. The speed was moderate, I didn't notice it moving particularly fast or slow.It was an orb shaped object, obviously silvery or chrome metallic, and as I said before strongly reflecting the sunlight. I didn't see any wings and it did not look like a plane or helicopter. I didn't hear any noise, but then again it was very high.I looked away for just a second, and when I looked back up, it had disappeared. I waited for a few minutes to see if it reappeared and it never did.
