Heavily enhanced still image of PJ-10 flyby movie. The image is reprojected from image #24 , with a simulated time diffrent from the image time of the raw. In his recent PJ-10 report, John Rogers suggested, that these darkish patches might be colored by soot as a result of lightning activity in thunderstorms.
