Toggle friends constantly. The ufo appears in a town, and stay there until you tap it or you get out of the friend's town. Staying in a single town when the UFO didn't appear when you came will never spawn an ufo there (well, if you quit and restart the same town will finally spawn one, of course).

PD: Usually UFOs only spawn once in a town: when you go and do the Daily Actions.
