Small Dark Spot

This image was obtained when the infrared spectrograph was mapping Neptune. It is the highest-resolution view of the small dark spot (D2) taken during the flyby. Banding around D2 indicates unseen strong winds, while structures within the dark spot suggest both active upwelling of clouds and rotation about the center. The V-shaped structure near the right edge of the bright area indicates that the spot rotates clockwise.
