Weather Forecast

The location of clouds in Neptune's atmosphere was used for testing the accuracy of Neptunian weather forecasts to aid in the selection of targets for the narrow-angle camera. Three of the four targeted features are visible here, and all three are close to their predicted locations. The Great Dark Spot with its bright white companion is slightly to the left of center. The small vivid Scooter is below and to the left, and Dark Spot 2 with its shiny core is below Scooter. Strong eastward winds, up to 644 kph (400 mph), caused the smaller dark spot to overtake and pass the larger one every five days.
