Working on my back porch at noon, I spied a white/silver object moving SSE just past a neighbor's tree. It was round, slightly elliptical to the naked eye, like a fat blimp or pinched orb, but completely silent and moving very quickly. It seemed solid. It hovered for a second and changed direction from its slight ascent SSE, to a steady altitude heading SSW. My first thought was a border drone, but it was far too big and round to be such, also silent for how close it was. I live in a town where air traffic is very rare, and the jets and helicopters that do fly over town are loud loud loud. I retrieved my phone and took a few hurried pictures before it went behind the tree. I ran around to the other side of the tree and glimpsed it briefly before it disappeared, heading west again. When I looked at the pictures, there was also a triangular object captured in one photo, but I did not see or notice it during the sighting.
