While standing outside my house with my dog, I noticed this rather large sphere object coming towards my direction from the west northwest direction towards an east southeast direction, I would calculate around 8 thousand feet judging from comercial flights passing over 10 thousand feet. It moved rather gracefully, NO sound, NO anti-collision lights of any type. I called my wife out to see it and as she came out of the house the object made a smooth curve turn towards the east, then it turned again smoothing towards the south. We both stared at it for a couple of seconds till it dissappeared or better yet dimmed out. There is no way it would have dimmed out so quickly. It would have been visible for another minute or so since it was brighter than any object in the sky including the visible planets to the east and west and any star in Orions Constellation at the moment. This thing was huge in brightness. Yellowish in appearance. Just dimmed out as it moved south.
