It looked like a white sphere but cannot be sure, it whas the whitest white I can think of , no pulsing of lights or sound, it was going from west to east, and from when I saw saw it until it went to the horizon was about twenty seconds. It looked like it wobbled but I can't be sure of this either. It didn't look real somehow ,very very strange. Could it have been a satellite, although I have seen satellites before and this was about the height of normal air planes that do come over quite frequently but not in this direction.
