This Voyager 2 high-resolution color image, taken 2 hours before closest approach, provides obvious evidence of vertical relief in Neptune's bright cloud streaks. These clouds were observed at 29 degrees North latitude near Neptune's east terminator . The linear clouds are stretched approximately along lines of constant latitude and the sun is toward the upper left. The sides of the clouds facing the sun are brighter than the surrounding cloud deck because they are more directly exposed to the sun.
Shadows are visible on the side opposite the sun.
