P-34630 Range: 10.5 million kilometers (6.5 million miles) This cylindrical projection view of Neptune uses five narrow-angle images equally spaced around the planet. They were taken by Voyager 2 over the course of a Neptunian day, an interval of about 18 hours. Latitude lines are horizontal in the image, and range from 80 degrees south to 30 degrees north of the equator. Near the center, the Great Dark Spot leaves a disturbed wave-like pattern that stretches around Neptune. Features further south move eastward at speeds up to 400 mph relative to the Great Dark Spot. The features are storms--moving cloud systems that persist for months or longer. The weather forecast for Neptune is therefore continued high winds and cold with little change in temperature.
