When Voyager 2 did a flyby of Neptune in 1989, a Great Dark Spot was discovered. The spot was an anticyclonic storm very similar to the Great Red Spot on Jupiter.
However later Neptune's spot disappeared. It was concluded that the spot was only a temporary storm, unlike Jupiter which has been raging for hundreds of years before it was even discovered.
Occasionally new spots appear on Neptune and vanish again hours later. Again, these are anticyclonic storms. Neptune is so far the stormiest planet discovered.
