Juno captured this brown barge at about 40 degrees south latitude, in the "South Tropical Zone" (STrZ), during its sixth perijove flyby on May 19, 2017 from an approximate distance of 12858 km. The image has been color and contrast enhanced and sharpened. The effects of global illumination have also been removed to increase the visibility of dimly lit features not far from the day-night terminator. Nadir resolution is ~8.5 km/pixel.
