**Some people think the [|Great Dark Spot of Neptune] is a storm, others think it is a hole in Neptune's Atmosphere layer of methane. The Great Dark Spot was discovered by the //Voyager// in 1989, than disappeared in 1994, than reappeared soon after. Instead of reappearing in the South where the spot originally was, it reappeared in the North. The cause of the spot moving to the North was probably when Neptune rotates, the spot moves the opposite direction Neptune spins.**
