was outside on patio grilling, observing unusually clear sky when noticed very shiny round object about the size of a quarter appear in the sky. It moved slightly up and diagonally. The entire time it did this is got smaller in the sky (same shiny reflective appearance) I went in the house to get binoculars to view object better. Upon my returning to the patio object was no longer in view. Occurred in under 3 minutes. I scanned for object with binoculars but saw nothing. As a side note, I did see several planes right before and after seeing object. The object DWARFED them in the sky.
