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.
This is in my opinion one of JunoCam's more spectacular observations of Jupiter because of the brown barge. The barge is located at ~40 degrees south latitude, in Jupiter's South Tropical Zone (StrZ). The color reminds me of when I saw Jupiter through a telescope during Christmas back in 2002 in exquisite seeing—by far the best I have ever experienced. There was almost no turbulence, the image was very steady, and the colors deeper and stronger than I have ever seen since—an unforgettable sight. One of the features visible was something looking like a brown barge. It had a deep and strong reddish-brownish color. The color of the barge in these JunoCam images remind me of the colors I saw back in 2002. One caveat though: Human 'color memory' is notoriously unreliable.
