Witnessed a metallic disc or sphere traveling East to West.

On the above date, while hanging our Christmas lights and looking up into a clear, blue sky, I witnessed a solid, round and metallic object fly over our neighborhood traveling East to West. The object clearly reflected sunlight. Unsure if the object was a sphere or a disc, but if I had to pick one, I would choose sphere. I only sighted the object for roughly 2 seconds, but was able to discern its shape and reflectivity. The object flew at a level flight level. Having experienced conventional aircraft flying at above the speed of sound, this object was moving much faster. It made no sound. Completely silent. The object flew almost directly above our home. I would estimate the object to have flown approximately 500 feet above my head, again, at a very high rate of speed. It continued West towards the Wasatch Mountains in the direction of Utah County just south of Macdonald Field. Upon witnessing the object, I ran into our home to inform my family. My wife informed me that our cable tv had also briefly cut out. There were no aircraft in the vicinity that I could visually identify. I had a brief but clear view of the object.
