The Great Dark Spot is a term used to describe a large, dark, storm system observed in the atmosphere of Neptune. It was first discovered by the Voyager 2 spacecraft during its flyby of Neptune in 1989. The Great Dark Spot is similar in appearance to the Great Red Spot on Jupiter but is smaller and more transient.
